/**
`AFHTTPRequestOperationManager` encapsulates the common patterns of communicating with a web application over HTTP, including request creation, response serialization, network reachability monitoring, and security, as well as request operation management.
## Subclassing Notes
Developers targeting iOS 7 or Mac OS X 10.9 or later that deal extensively with a web service are encouraged to subclass `AFHTTPSessionManager`, providing a class method that returns a shared singleton object on which authentication and other configuration can be shared across the application.
For developers targeting iOS 6 or Mac OS X 10.8 or earlier, `AFHTTPRequestOperationManager` may be used to similar effect.
## Methods to Override
To change the behavior of all request operation construction for an `AFHTTPRequestOperationManager` subclass, override `HTTPRequestOperationWithRequest:success:failure`.
## Serialization
Requests created by an HTTP client will contain default headers and encode parameters according to the `requestSerializer` property, which is an object conforming to `<AFURLRequestSerialization>`.
Responses received from the server are automatically validated and serialized by the `responseSerializers` property, which is an object conforming to `<AFURLResponseSerialization>`
## URL Construction Using Relative Paths
For HTTP convenience methods, the request serializer constructs URLs from the path relative to the `-baseURL`, using `NSURL +URLWithString:relativeToURL:`, when provided. If `baseURL` is `nil`, `path` needs to resolve to a valid `NSURL` object using `NSURL +URLWithString:`.
Below are a few examples of how `baseURL` and relative paths interact:
NSURL *baseURL = [NSURL URLWithString:@"http://example.com/v1/"];
[NSURL URLWithString:@"foo" relativeToURL:baseURL]; // http://example.com/v1/foo
[NSURL URLWithString:@"foo?bar=baz" relativeToURL:baseURL]; // http://example.com/v1/foo?bar=baz
[NSURL URLWithString:@"/foo" relativeToURL:baseURL]; // http://example.com/foo
[NSURL URLWithString:@"foo/" relativeToURL:baseURL]; // http://example.com/v1/foo
[NSURL URLWithString:@"/foo/" relativeToURL:baseURL]; // http://example.com/foo/
[NSURL URLWithString:@"http://example2.com/" relativeToURL:baseURL]; // http://example2.com/
Also important to note is that a trailing slash will be added to any `baseURL` without one. This would otherwise cause unexpected behavior when constructing URLs using paths without a leading slash.
## Network Reachability Monitoring
Network reachability status and change monitoring is available through the `reachabilityManager` property. Applications may choose to monitor network reachability conditions in order to prevent or suspend any outbound requests. See `AFNetworkReachabilityManager` for more details.
## NSSecureCoding & NSCopying Caveats
`AFHTTPRequestOperationManager` conforms to the `NSSecureCoding` and `NSCopying` protocols, allowing operations to be archived to disk, and copied in memory, respectively. There are a few minor caveats to keep in mind, however:
- Archives and copies of HTTP clients will be initialized with an empty operation queue.
- NSSecureCoding cannot serialize / deserialize block properties, so an archive of an HTTP client will not include any reachability callback block that may be set.

/**
`AFHTTPSessionManager` is a subclass of `AFURLSessionManager` with convenience methods for making HTTP requests. When a `baseURL` is provided, requests made with the `GET` / `POST` / et al. convenience methods can be made with relative paths.
## Subclassing Notes
Developers targeting iOS 7 or Mac OS X 10.9 or later that deal extensively with a web service are encouraged to subclass `AFHTTPSessionManager`, providing a class method that returns a shared singleton object on which authentication and other configuration can be shared across the application.
For developers targeting iOS 6 or Mac OS X 10.8 or earlier, `AFHTTPRequestOperationManager` may be used to similar effect.
## Methods to Override
To change the behavior of all data task operation construction, which is also used in the `GET` / `POST` / et al. convenience methods, override `dataTaskWithRequest:completionHandler:`.
## Serialization
Requests created by an HTTP client will contain default headers and encode parameters according to the `requestSerializer` property, which is an object conforming to `<AFURLRequestSerialization>`.
Responses received from the server are automatically validated and serialized by the `responseSerializers` property, which is an object conforming to `<AFURLResponseSerialization>`
## URL Construction Using Relative Paths
For HTTP convenience methods, the request serializer constructs URLs from the path relative to the `-baseURL`, using `NSURL +URLWithString:relativeToURL:`, when provided. If `baseURL` is `nil`, `path` needs to resolve to a valid `NSURL` object using `NSURL +URLWithString:`.
Below are a few examples of how `baseURL` and relative paths interact:
NSURL *baseURL = [NSURL URLWithString:@"http://example.com/v1/"];
[NSURL URLWithString:@"foo" relativeToURL:baseURL]; // http://example.com/v1/foo
[NSURL URLWithString:@"foo?bar=baz" relativeToURL:baseURL]; // http://example.com/v1/foo?bar=baz
[NSURL URLWithString:@"/foo" relativeToURL:baseURL]; // http://example.com/foo
[NSURL URLWithString:@"foo/" relativeToURL:baseURL]; // http://example.com/v1/foo
[NSURL URLWithString:@"/foo/" relativeToURL:baseURL]; // http://example.com/foo/
[NSURL URLWithString:@"http://example2.com/" relativeToURL:baseURL]; // http://example2.com/
Also important to note is that a trailing slash will be added to any `baseURL` without one. This would otherwise cause unexpected behavior when constructing URLs using paths without a leading slash.
@warning Managers for background sessions must be owned for the duration of their use. This can be accomplished by creating an application-wide or shared singleton instance.

/**
`AFURLConnectionOperation` is a subclass of `NSOperation` that implements `NSURLConnection` delegate methods.
## Subclassing Notes
This is the base class of all network request operations. You may wish to create your own subclass in order to implement additional `NSURLConnection` delegate methods (see "`NSURLConnection` Delegate Methods" below), or to provide additional properties and/or class constructors.
If you are creating a subclass that communicates over the HTTP or HTTPS protocols, you may want to consider subclassing `AFHTTPRequestOperation` instead, as it supports specifying acceptable content types or status codes.
## NSURLConnection Delegate Methods
`AFURLConnectionOperation` implements the following `NSURLConnection` delegate methods:
- `connection:didReceiveResponse:`
- `connection:didReceiveData:`
- `connectionDidFinishLoading:`
- `connection:didFailWithError:`
- `connection:didSendBodyData:totalBytesWritten:totalBytesExpectedToWrite:`
- `connection:willCacheResponse:`
- `connectionShouldUseCredentialStorage:`
- `connection:needNewBodyStream:`
- `connection:willSendRequestForAuthenticationChallenge:`
If any of these methods are overridden in a subclass, they _must_ call the `super` implementation first.
## Callbacks and Completion Blocks
The built-in `completionBlock` provided by `NSOperation` allows for custom behavior to be executed after the request finishes. It is a common pattern for class constructors in subclasses to take callback block parameters, and execute them conditionally in the body of its `completionBlock`. Make sure to handle cancelled operations appropriately when setting a `completionBlock` (i.e. returning early before parsing response data). See the implementation of any of the `AFHTTPRequestOperation` subclasses for an example of this.
Subclasses are strongly discouraged from overriding `setCompletionBlock:`, as `AFURLConnectionOperation`'s implementation includes a workaround to mitigate retain cycles, and what Apple rather ominously refers to as ["The Deallocation Problem"](http://developer.apple.com/library/ios/#technotes/tn2109/).
## SSL Pinning
Relying on the CA trust model to validate SSL certificates exposes your app to security vulnerabilities, such as man-in-the-middle attacks. For applications that connect to known servers, SSL certificate pinning provides an increased level of security, by checking server certificate validity against those specified in the app bundle.
SSL with certificate pinning is strongly recommended for any application that transmits sensitive information to an external webservice.
Connections will be validated on all matching certificates with a `.cer` extension in the bundle root.
## NSCoding & NSCopying Conformance
`AFURLConnectionOperation` conforms to the `NSCoding` and `NSCopying` protocols, allowing operations to be archived to disk, and copied in memory, respectively. However, because of the intrinsic limitations of capturing the exact state of an operation at a particular moment, there are some important caveats to keep in mind:
### NSCoding Caveats
- Encoded operations do not include any block or stream properties. Be sure to set `completionBlock`, `outputStream`, and any callback blocks as necessary when using `-initWithCoder:` or `NSKeyedUnarchiver`.
- Operations are paused on `encodeWithCoder:`. If the operation was encoded while paused or still executing, its archived state will return `YES` for `isReady`. Otherwise, the state of an operation when encoding will remain unchanged.
### NSCopying Caveats
- `-copy` and `-copyWithZone:` return a new operation with the `NSURLRequest` of the original. So rather than an exact copy of the operation at that particular instant, the copying mechanism returns a completely new instance, which can be useful for retrying operations.
- A copy of an operation will not include the `outputStream` of the original.
- Operation copies do not include `completionBlock`, as it often strongly captures a reference to `self`, which would otherwise have the unintuitive side-effect of pointing to the _original_ operation when copied.

@discussion There is a bug in `NSURLSessionTask` that causes requests to not send a `Content-Length` header when streaming contents from an HTTP body, which is notably problematic when interacting with the Amazon S3 webservice. As a workaround, this method takes a request constructed with `multipartFormRequestWithMethod:URLString:parameters:constructingBodyWithBlock:error:`, or any other request with an `HTTPBodyStream`, writes the contents to the specified file and returns a copy of the original request with the `HTTPBodyStream` property set to `nil`.

Throttles request bandwidth by limiting the packet size and adding a delay for each chunk read from the upload stream.
When uploading over a 3G or EDGE connection, requests may fail with "request body stream exhausted". Setting a maximum packet size and delay according to the recommended values (`kAFUploadStream3GSuggestedPacketSize` and `kAFUploadStream3GSuggestedDelay`) lowers the risk of the input stream exceeding its allocated bandwidth. Unfortunately, there is no definite way to distinguish between a 3G, EDGE, or LTE connection over `NSURLConnection`. As such, it is not recommended that you throttle bandwidth based solely on network reachability. Instead, you should consider checking for the "request body stream exhausted" in a failure block, and then retrying the request with throttled bandwidth.

/**
`AFURLSessionManager` creates and manages an `NSURLSession` object based on a specified `NSURLSessionConfiguration` object, which conforms to `<NSURLSessionTaskDelegate>`, `<NSURLSessionDataDelegate>`, `<NSURLSessionDownloadDelegate>`, and `<NSURLSessionDelegate>`.
## Subclassing Notes
This is the base class for `AFHTTPSessionManager`, which adds functionality specific to making HTTP requests. If you are looking to extend `AFURLSessionManager` specifically for HTTP, consider subclassing `AFHTTPSessionManager` instead.
## NSURLSession & NSURLSessionTask Delegate Methods
`AFURLSessionManager` implements the following delegate methods:
### `NSURLSessionDelegate`
- `URLSession:didBecomeInvalidWithError:`
- `URLSession:didReceiveChallenge:completionHandler:`
- `URLSessionDidFinishEventsForBackgroundURLSession:`
### `NSURLSessionTaskDelegate`
- `URLSession:willPerformHTTPRedirection:newRequest:completionHandler:`
- `URLSession:task:didReceiveChallenge:completionHandler:`
- `URLSession:task:didSendBodyData:totalBytesSent:totalBytesExpectedToSend:`
- `URLSession:task:didCompleteWithError:`
### `NSURLSessionDataDelegate`
- `URLSession:dataTask:didReceiveResponse:completionHandler:`
- `URLSession:dataTask:didBecomeDownloadTask:`
- `URLSession:dataTask:didReceiveData:`
- `URLSession:dataTask:willCacheResponse:completionHandler:`
### `NSURLSessionDownloadDelegate`
- `URLSession:downloadTask:didFinishDownloadingToURL:`
- `URLSession:downloadTask:didWriteData:totalBytesWritten:totalBytesWritten:totalBytesExpectedToWrite:`
- `URLSession:downloadTask:didResumeAtOffset:expectedTotalBytes:`
If any of these methods are overridden in a subclass, they _must_ call the `super` implementation first.
## Network Reachability Monitoring
Network reachability status and change monitoring is available through the `reachabilityManager` property. Applications may choose to monitor network reachability conditions in order to prevent or suspend any outbound requests. See `AFNetworkReachabilityManager` for more details.
## NSCoding Caveats
- Encoded managers do not include any block properties. Be sure to set delegate callback blocks when using `-initWithCoder:` or `NSKeyedUnarchiver`.
## NSCopying Caveats
- `-copy` and `-copyWithZone:` return a new manager with a new `NSURLSession` created from the configuration of the original.
- Operation copies do not include any delegate callback blocks, as they often strongly captures a reference to `self`, which would otherwise have the unintuitive side-effect of pointing to the _original_ session manager when copied.
@warning Managers for background sessions must be owned for the duration of their use. This can be accomplished by creating an application-wide or shared singleton instance.

iOS 7 and iOS 8 differ in NSURLSessionTask implementation, which makes the next bit of code a bit tricky.
Many Unit Tests have been built to validate as much of this behavior has possible.
Here is what we know:
- NSURLSessionTasks are implemented with class clusters, meaning the class you request from the API isn't actually the type of class you will get back.
- Simply referencing `[NSURLSessionTask class]` will not work. You need to ask an `NSURLSession` to actually create an object, and grab the class from there.
- On iOS 7, `localDataTask` is a `__NSCFLocalDataTask`, which inherits from `__NSCFLocalSessionTask`, which inherits from `__NSCFURLSessionTask`.
- On iOS 8, `localDataTask` is a `__NSCFLocalDataTask`, which inherits from `__NSCFLocalSessionTask`, which inherits from `NSURLSessionTask`.
- On iOS 7, `__NSCFLocalSessionTask` and `__NSCFURLSessionTask` are the only two classes that have their own implementations of `resume` and `suspend`, and `__NSCFLocalSessionTask` DOES NOT CALL SUPER. This means both classes need to be swizzled.
- On iOS 8, `NSURLSessionTask` is the only class that implements `resume` and `suspend`. This means this is the only class that needs to be swizzled.
- Because `NSURLSessionTask` is not involved in the class hierarchy for every version of iOS, its easier to add the swizzled methods to a dummy class and manage them there.
Some Assumptions:
- No implementations of `resume` or `suspend` call super. If this were to change in a future version of iOS, we'd need to handle it.
- No background task classes override `resume` or `suspend`
The current solution:
1) Grab an instance of `__NSCFLocalDataTask` by asking an instance of `NSURLSession` for a data task.
2) Grab a pointer to the original implementation of `af_resume`
3) Check to see if the current class has an implementation of resume. If so, continue to step 4.
4) Grab the super class of the current class.
5) Grab a pointer for the current class to the current implementation of `resume`.
6) Grab a pointer for the super class to the current implementation of `resume`.
7) If the current class implementation of `resume` is not equal to the super class implementation of `resume` AND the current implementation of `resume` is not equal to the original implementation of `af_resume`, THEN swizzle the methods
8) Set the current class to the super class, and repeat steps 3-8

/**
`AFNetworkActivityIndicatorManager` manages the state of the network activity indicator in the status bar. When enabled, it will listen for notifications indicating that a network request operation has started or finished, and start or stop animating the indicator accordingly. The number of active requests is incremented and decremented much like a stack or a semaphore, and the activity indicator will animate so long as that number is greater than zero.
You should enable the shared instance of `AFNetworkActivityIndicatorManager` when your application finishes launching. In `AppDelegate application:didFinishLaunchingWithOptions:` you can do so with the following code:
[[AFNetworkActivityIndicatorManager sharedManager] setEnabled:YES];
By setting `enabled` to `YES` for `sharedManager`, the network activity indicator will show and hide automatically as requests start and finish. You should not ever need to call `incrementActivityCount` or `decrementActivityCount` yourself.
See the Apple Human Interface Guidelines section about the Network Activity Indicator for more information:
http://developer.apple.com/library/iOS/#documentation/UserExperience/Conceptual/MobileHIG/UIElementGuidelines/UIElementGuidelines.html#//apple_ref/doc/uid/TP40006556-CH13-SW44

* The NIAttributedLabel class provides support for displaying rich text with selectable links and

*
* Differences between UILabel and NIAttributedLabel:
*
* - @c NSLineBreakByTruncatingHead and @c NSLineBreakByTruncatingMiddle only apply to single
* lines and will not wrap the label regardless of the @c numberOfLines property. To wrap lines
* with any of these line break modes you must explicitly add newline characters to the string.
* - When you assign an NSString to the text property the attributed label will create an
* attributed string that inherits all of the label's current styles.
* - Text is aligned vertically to the top of the bounds by default rather than centered. You can
* change this behavior using @link NIAttributedLabel::verticalTextAlignment verticalTextAlignment@endlink.
* - CoreText fills the frame with glyphs until they no longer fit. This is an important difference
* from UILabel because it means that CoreText will not add any glyphs that won't fit in the
* frame, while UILabel does. This can result in empty NIAttributedLabels if your frame is too
* small where UILabel would draw clipped text. It is recommended that you use sizeToFit to get
* the correct dimensions of the attributed label before setting the frame.
*
* NIAttributedLabel implements the UIAccessibilityContainer methods to expose each link as an
* accessibility item.

/**
* @defgroup NimbusAttributedLabel Nimbus Attributed Label
* @{
*
* <div id="github" feature="attributedlabel"></div>
*
* The Nimbus Attributed Label is a UILabel that uses NSAttributedString to render rich text labels
* with links using CoreText.
*
* @image html NIAttributedLabelExample1.png "A mashup of possible label styles"
*
* <h2>Minimum Requirements</h2>
*
* Required frameworks:
*
* - Foundation.framework
* - UIKit.framework
* - CoreText.framework
* - QuartzCore.framework
*
* Minimum Operating System: <b>iOS 6.0</b>
*
* Source located in <code>src/attributedlabel/src</code>
*
@code
#import "NimbusAttributedLabel.h"
@endcode
*
* <h2>Basic Use</h2>
*
* NIAttributedLabel is a subclass of UILabel. The attributed label maintains an <a href="http://developer.apple.com/library/ios/#documentation/Cocoa/Reference/Foundation/Classes/NSAttributedString_Class/Reference/Reference.html">NSAttributedString</a>
* object internally which is used in conjunction with CoreText to draw rich-text labels. A number
* of helper methods for modifying the text style are provided. If you need to directly modify the
* internal NSAttributedString you may do so by accessing the @c attributedText property.
*
@code
NIAttributedLabel* label = [[NIAttributedLabel alloc] initWithFrame:CGRectZero];
// The internal NSAttributedString will inherit all of UILabel's text attributes when we assign
// text.
label.text = @"Nimbus";
@endcode
*
*
* <h2>Interface Builder</h2>
*
* You can use an attributed label within Interface Builder by creating a UILabel and changing its
* class to NIAttributedLabel. This will allow you to set styles that apply to
* the entire string. If you want to style specific parts of the string then you will
* need to do this in code.
*
* @image html NIAttributedLabelIB.png "Configuring an attributed label in Interface Builder"
*
*
* <h2>Feature Overview</h2>
*
* - Automatic link detection using data detectors
* - Link attributes
* - Explicit links
* - Underlining
* - Justifying paragraphs
* - Stroking
* - Kerning
* - Setting rich text styles at specific ranges
*
*
* <h3>Automatic Link Detection</h3>
*
* Automatic link detection is provided using <a href="https://developer.apple.com/library/mac/#documentation/Foundation/Reference/NSDataDetector_Class/Reference/Reference.html">NSDataDetector</a>.
* Link detection is off by default and can be enabled by setting
* @link NIAttributedLabel::autoDetectLinks autoDetectLinks@endlink to YES. You may configure
* the types of data that are detected by modifying the
* @link NIAttributedLabel::dataDetectorTypes dataDetectorTypes@endlink property. By default only
* urls will be detected.
*
* @attention NIAttributedLabel is not designed to detect html anchor tags (i.e. <a>). If
* you want to attach a URL to a given range of text you must use
* @link NIAttributedLabel::addLink:range: addLink:range:@endlink.
* You can add links to the attributed string using the attribute
* NIAttributedLabelLinkAttributeName. The NIAttributedLabelLinkAttributeName value
* must be a NSTextCheckingResult.
*
* @image html NIAttributedLabel_autoDetectLinksOff.png "Before enabling autoDetectLinks"
*
@code
// Enable link detection on the label.
myLabel.autoDetectLinks = YES;
@endcode
*
* @image html NIAttributedLabel_autoDetectLinksOn.png "After enabling autoDetectLinks"
*
* Enabling automatic link detection will automatically enable user interation with the label view
* so that the user can tap the detected links.
*
* <h3>Link Attributes</h3>
*
* Detected links will use @link NIAttributedLabel::linkColor linkColor@endlink and
* @link NIAttributedLabel::highlightedLinkColor highlightedLinkColor@endlink to differentiate
* themselves from standard text. highlightedLinkColor is the color of the highlighting frame
* around the text. You can easily add underlines to links by enabling
* @link NIAttributedLabel::linksHaveUnderlines linksHaveUnderlines@endlink. You can customize link
* attributes in more detail by directly modifying the
* @link NIAttributedLabel::attributesForLinks attributesForLinks@endlink property.
*
* @image html NIAttributedLabelLinkAttributes.png "Link attributes"
*
* <h4>A note on performance</h4>
*
* Automatic link detection is expensive. You can choose to defer automatic link detection by
* enabling @link NIAttributedLabel::deferLinkDetection deferLinkDetection@endlink. This will move
* the link detection to a separate background thread. Once the links have been detected the label
* will be redrawn.
*
*
* <h3>Handling Taps on Links</h3>
*
* The NIAttributedLabelDelegate protocol allows you to handle when the user taps on a given link.
* The protocol methods provide the tap point as well as the data pertaining to the tapped link.
*
@code
- (void)attributedLabel:(NIAttributedLabel *)attributedLabel didSelectTextCheckingResult:(NSTextCheckingResult *)result atPoint:(CGPoint)point {
[[UIApplication sharedApplication] openURL:result.URL];
}
@endcode
*
* <h3>Explicit Links</h3>
*
* Links can be added explicitly using
* @link NIAttributedLabel::addLink:range: addLink:range:@endlink.
*
@code
// Add a link to the string 'nimbus' in myLabel.
[myLabel addLink:[NSURL URLWithString:@"nimbus://custom/url"]
range:[myLabel.text rangeOfString:@"nimbus"]];
@endcode
*
*
* <h3>Underlining Text</h3>
*
* To underline an entire label:
*
@code
// Underline the whole label with a single line.
myLabel.underlineStyle = kCTUnderlineStyleSingle;
@endcode
*
* Underline modifiers can also be added:
*
@code
// Underline the whole label with a dash dot single line.
myLabel.underlineStyle = kCTUnderlineStyleSingle;
myLabel.underlineStyleModifier = kCTUnderlinePatternDashDot;
@endcode
*
* Underline styles and modifiers can be mixed to create the desired effect, which is shown in
* the following screenshot:
*
* @image html NIAttributedLabelExample2.png "Underline styles"
*
* @remarks Underline style kCTUnderlineStyleThick only over renders a single line.
*
*
* <h3>Justifying Paragraphs</h3>
*
* NIAttributedLabel supports justified text using UITextAlignmentJustify.
*
@code
myLabel.textAlignment = UITextAlignmentJustify;
@endcode
*
*
* <h3>Stroking Text</h3>
*
@code
myLabel.strokeWidth = 3.0;
myLabel.strokeColor = [UIColor blackColor];
@endcode
*
* A positive stroke width will render only the stroke.
*
* @image html NIAttributedLabelExample3.png "Black stroke of 3.0"
*
* A negative number will fill the stroke with textColor:
*
@code
myLabel.strokeWidth = -3.0;
myLabel.strokeColor = [UIColor blackColor];
@endcode
*
* @image html NIAttributedLabelExample4.png "Black stroke of -3.0"
*
*
* <h3>Kerning Text</h3>
*
* Kerning is the space between characters in points. A positive kern will increase the space
* between letters. Correspondingly a negative number will decrease the space.
*
@code
myLabel.textKern = -6.0;
@endcode
*
* @image html NIAttributedLabelExample5.png "Text kern of -6.0"
*
*
* <h3>Setting Rich Text styles at specific ranges</h3>
*
* All styles that can be added to the whole label (as well as default UILabel styles like font and
* text color) can be added to just a range of text.
*
@code
[myLabel setTextColor:[UIColor orangeColor] range:[myLabel.text rangeOfString:@"Nimbus"]];
[myLabel setFont:[UIFont boldSystemFontOfSize:22] range:[myLabel.text rangeOfString:@"iOS"]];
@endcode

*
* This Nimbus badge view is a UIView that draws a customizable notification badge-like view.
*
* @image html badge-iphone-example1.png "Screenshot of a Nimbus badge on the iPhone"
*
* <h2>Minimum Requirements</h2>
*
* Required frameworks:
*
* - Foundation.framework
* - UIKit.framework
*
* Minimum Operating System: <b>iOS 4.0</b>
*
* Source located in <code>src/badge/src</code>
*
@code
#import "NimbusBadge.h"
@endcode
*
* <h2>Basic Use</h2>
*
* The badge view works much like UILabel. Once you've assigned text and configured the attributes
* you should call sizeToFit to have the badge determine its ideal size.
*
@code
NIBadgeView* badgeView = [[NIBadgeView alloc] initWithFrame:CGRectZero];
badgeView.text = @"7";
[badgeView sizeToFit];
[self.view addSubview:badgeView];

/**
* The NICollectionViewActions class provides an interface for attaching actions to objects in a
* NICollectionViewModel.
*
* <h2>Basic Use</h2>
*
* NICollectionViewModel and NICollectionViewActions cooperate to solve two related tasks: data
* representation and user actions, respectively. A NICollectionViewModel is composed of objects and
* NICollectionViewActions maintains a mapping of actions to these objects. The object's attached
* actions are executed when the user interacts with the cell representing an object.
*
* <h2>Delegate Forwarding</h2>
*
* Your delegate implementation can call the listed collectionView: methods in order for the
* collection view to respond to user actions. Notably shouldHighlightItemAtIndexPath: allows
* cells to be highlighted only if the cell's object has an attached action.
* didSelectItemAtIndexPath: will execute the object's attached tap actions.
*
* If you use the delegate forwarders your collection view's data source must be an instance of
* NICollectionViewModel.

* A simple factory for creating collection view cells from objects.

* conforms to the NICollectionViewCellObject protocol. The created cell should ideally conform to
* the NICollectionViewCell protocol. If it does, the object will be passed to it via
* @link NICollectionViewCell::shouldUpdateCellWithObject: shouldUpdateCellWithObject:@endlink
* before the factory method returns.
*
* This factory is designed to be used with NICollectionViewModel, though one could easily use
* it with other collection view data source implementations simply by providing nil for the
* collection view model argument.
*
* If you instantiate an NICollectionViewCellFactory then you can provide explicit mappings from
* objects to cells. This is helpful if the effort required to implement the NICollectionViewCell
* protocol on an object outweighs the benefit of using the factory, i.e. when you want to map

/**
* The NIMutableCollectionViewModel class is a mutable collection view model.
*
* When modifications are made to the model there are two ways to reflect the changes in the
* collection view.
*
* - Call reloadData on the collection view. This is the most destructive way to update the
* collection view.
* - Call insert/delete/reload methods on the collection view with the retuned index path arrays.
*
* The latter option is the recommended approach to adding new cells to a collection view. Each
* method in the mutable collection view model returns a data structure that can be used to inform
* the collection view of the exact modifications that have been made to the model.
*
* Example of adding a new section:
@code
// Appends a new section to the end of the model.
NSIndexSet* indexSet = [self.model addSectionWithTitle:@"New section"];
// Appends a cell to the last section in the model (in this case, the new section we just created).
[self.model addObject:[TestTextCollectionViewCellObject objectWithTitle:@"A cell"]];
// Inform the collection view that we've modified the model.

* All attachment methods return the object that was provided. This makes it simple to attach
* actions within an array creation statement.
*
* Actions come in two forms: blocks and selector invocations. Both can be attached to an object
* for each type of action and both will be executed, with the block being executed first. Blocks
* should be used for simple executions while selectors should be used when the action is complex.
*
* The following is an example of using NITableViewActions:
*
@code
NSArray *objects = @[
[NITitleCellObject objectWithTitle:@"Implicit tap handler"],
[self.actions attachToObject:[NITitleCellObject objectWithTitle:@"Explicit tap handler"]
tapBlock:
^BOOL(id object, id target) {
NSLog(@"Object was tapped with an explicit action: %@", object);
}]
];
[self.actions attachToClass:[NITitleCellObject class]
tapBlock:
^BOOL(id object, id target) {
NSLog(@"Object was tapped: %@", object);
}];
@endcode

* For common system metrics.
*
* If you work with system metrics in any way it can be a pain in the ass to figure out what the
* exact metrics are. Figuring out how long it takes the status bar to animate is not something you
* should be spending your time on. The metrics in this file are provided as a means of unifying a
* number of system metrics for use in your applications.
*
* <h2>What Qualifies as a Common Metric</h2>
*
* Common metrics are system components, such as the dimensions of a toolbar in
* a particular orientation or the duration of a standard animation. This is
* not the place to put feature-specific metrics, such as the height of a photo scrubber
* view.
*
* <h2>Examples</h2>
*
* <h3>Positioning a Toolbar</h3>
*
* The following example updates the position and height of a toolbar when the device
* orientation is changing. This ensures that, in landscape mode on the iPhone, the toolbar
* is slightly shorter to accomodate the smaller height of the screen.
*
* @code
* - (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
* duration:(NSTimeInterval)duration {
* [super willAnimateRotationToInterfaceOrientation:toInterfaceOrientation duration:duration];

/**
* For classic computer science data structures.
*
* NILinkedList has been deprecated and will soon be removed altogether. Use NSMutableOrderedSet
* instead.
*
* iOS provides most of the important data structures such as arrays, dictionaries, and sets.
* However, it is missing some lesser-used data structures such as linked lists. Nimbus makes
* use of the linked list data structure to provide an efficient, least-recently-used cache
* removal policy for its in-memory cache, NIMemoryCache.
*
*
* <h2>Comparison of Data Structures</h2>
*
*<pre>
* Requirement | NILinkedList | NSArray | NSSet | NSDictionary
* =====================================================================
* Instant arbitrary | YES | NO | YES | YES
* insertion/deletion | [1] | | |
* ---------------------------------------------------------------------
* Consistent object | YES | YES | NO | NO
* ordering | | | |
* ---------------------------------------------------------------------
* Checking for object | NO | NO | YES | NO
* existence quickly | | | |
* ---------------------------------------------------------------------
* Instant object access | YES | NO | YES | YES
* | [1] | | | [2]
* ---------------------------------------------------------------------</pre>
*
* - [1] Note that being able to instantly remove and access objects in a NILinkedList
* requires additional overhead of maintaining NILinkedListLocation objects in your
* code. If this is your only requirement, then it's likely simpler to use an NSSet.
* A linked list <i>is</i> worth using if you also need consistent ordering, seeing
* as neither NSSet nor NSDictionary provide this.
* - [2] This assumes you are accessing the object with its key.
*
*
* <h2>Why NILinkedList was Built</h2>
*
* NILinkedList was built to solve a specific need in Nimbus' in-memory caches of having
* a collection that guaranteed ordering, constant-time appending, and constant
* time removal of arbitrary objects.
* NSArray does not guarantee constant-time removal of objects, NSSet does not enforce ordering
* (though the new NSOrderedSet introduced in iOS 5 does), and NSDictionary also does not
* enforce ordering.
*
*
* @ingroup NimbusCore

@interface NILinkedListLocation : NSObject
@end
/**
* A singly linked list implementation.
*
* This data structure provides constant time insertion and deletion of objects
* in a collection.
*
* A linked list is different from an NSMutableArray solely in the runtime of adding and
* removing objects. It is always possible to remove objects from both the beginning and end of
* a linked list in constant time, contrasted with an NSMutableArray where removing an object
* from the beginning of the list could result in O(N) linear time, where
* N is the number of objects in the collection when the action is performed.
* If an object's location is known, it is possible to get O(1) constant time removal
* with a linked list, where an NSMutableArray would get at best O(N) linear time.
*
* This collection implements NSFastEnumeration which allows you to use foreach-style
* iteration on the linked list. If you would like more control over the iteration of the
* linked list you can use
* <code>-[NILinkedList @link NILinkedList::objectEnumerator objectEnumerator@endlink]</code>
*
*
* <h2>When You Should Use a Linked List</h2>
*
* Linked lists should be used when you need guaranteed constant-time performance characteristics
* for adding arbitrary objects to and removing arbitrary objects from a collection that
* also enforces consistent ordering.
*
* Linked lists are used in NIMemoryCache to implement an efficient, least-recently used
* collection for in-memory caches. It is important that these caches use a collection with
* guaranteed constant-time properties because in-memory caches must operate as fast as
* possible in order to avoid locking up the UI. Specifically, in-memory caches could
* potentially have thousands of objects. Every time we access one of these objects we move
* its lru placement to the end of the lru list. If we were to use an NSArray for this data
* structure we could easily run into an O(N^2) exponential-time operation which is
* absolutely unacceptable.

/**
* @class NILinkedList
*
* <h2>Modifying a linked list</h2>
*
* To add an object to a linked list, you may use @link NILinkedList::addObject: addObject:@endlink.
*
* @code
* [ll addObject:object];
* @endcode
*
* To remove some arbitrary object in linear time (meaning we must perform a scan of the list), use
* @link NILinkedList::removeObject: removeObject:@endlink
*
* @code
* [ll removeObject:object];
* @endcode
*
* Note that using a linked list in this way is way is identical to using an
* NSMutableArray in performance time.
*
*
* <h2>Accessing a Linked List</h2>
*
* You can access the first and last objects with constant time by using
* @link NILinkedList::firstObject firstObject@endlink and
* @link NILinkedList::lastObject lastObject@endlink.
*
* @code
* id firstObject = ll.firstObject;
* id lastObject = ll.lastObject;
* @endcode
*
*
* <h2>Traversing a Linked List</h2>
*
* NILinkedList implements the NSFastEnumeration protocol, allowing you to use foreach-style
* iteration over the objects of a linked list. Note that you cannot modify a linked list
* during fast iteration and doing so will fire an assertion.
*
* @code
* for (id object in ll) {
* // perform operations on the object
* }
* @endcode
*
* If you need to modify the linked list while traversing it, an acceptable algorithm is to
* successively remove either the head or tail object, depending on the order in which you wish
* to traverse the linked list.
*
* <h3>Traversing Forward by Removing Objects from the List</h3>
*
* @code
* while (nil != ll.firstObject) {
* id object = [ll firstObject];
*
* // Remove the head of the linked list in constant time.
* [ll removeFirstObject];
* }
* @endcode
*
* <h3>Traversing Backward by Removing Objects from the List</h3>
*
* @code
* while (nil != ll.lastObject) {
* id object = [ll lastObject];
*
* // Remove the tail of the linked list in constant time.
* [ll removeLastObject];
* }
* @endcode
*
*
* <h2>Examples</h2>
*
*
* <h3>Building a first-in-first-out list of operations</h3>
*
* @code
* NILinkedList* ll = [NILinkedList linkedList];
*
* // Add the operations to the linked list like you would an array.
* [ll addObject:operation1];
*
* // Each addObject call appends the object to the end of the linked list.
* [ll addObject:operation2];
*
* while (nil != ll.firstObject) {
* NSOperation* op1 = [ll firstObject];
* // Process the operation...
*
* // Remove the head of the linked list in constant time.
* [ll removeFirstObject];
* }
* @endcode
*
*
* <h3>Removing an item from the middle of the list</h3>
*
* @code
* NILinkedList* ll = [NILinkedList linkedList];
*
* [ll addObject:obj1];
* [ll addObject:obj2];
* [ll addObject:obj3];
* [ll addObject:obj4];
*
* // Find an object in the linked list in linear time.
* NILinkedListLocation* location = [ll locationOfObject:obj3];
*
* // Remove the object in constant time.
* [ll removeObjectAtLocation:location];
*
* // Location is no longer valid at this point.
* location = nil;
*
* // Remove an object in linear time. This is simply a more concise version of the above.
* [ll removeObject:obj4];
*
* // We would use the NILinkedListLocation to remove the object if we were storing the location
* // in an external data structure and wanted constant time removal, for example. See
* // NIMemoryCache for an example of this in action.
* @endcode
*
* @sa NIMemoryCache
*
*
* <h3>Using the location object for constant time operations</h3>
*
* @code
* NILinkedList* ll = [NILinkedList linkedList];
*
* [ll addObject:obj1];
* NILinkedListLocation* location = [ll addObject:obj2];
* [ll addObject:obj3];
* [ll addObject:obj4];
*
* // Remove the second object in constant time.
* [ll removeObjectAtLocation:location];
*
* // Location is no longer valid at this point.
* location = nil;

/**
* For inspecting code and writing to logs in debug builds.
*
* Nearly all of the following macros will only do anything if the DEBUG macro is defined.
* The recommended way to enable the debug tools is to specify DEBUG in the "Preprocessor Macros"
* field in your application's Debug target settings. Be careful not to set this for your release
* or app store builds because this will enable code that may cause your app to be rejected.
*
*
* <h2>Debug Assertions</h2>
*
* Debug assertions are a lightweight "sanity check". They won't crash the app, nor will they
* be included in release builds. They <i>will</i> halt the app's execution when debugging so
* that you can inspect the values that caused the failure.
*
* @code
* NIDASSERT(statement);
* @endcode
*
* If <i>statement</i> is false, the statement will be written to the log and if a debugger is
* attached, the app will break on the assertion line.
*
*
* <h2>Debug Logging</h2>
*
* @code
* NIDPRINT(@"formatted log text %d", param1);
* @endcode
*
* Print the given formatted text to the log.
*
* @code
* NIDPRINTMETHODNAME();
* @endcode
*
* Print the current method name to the log.
*
* @code
* NIDCONDITIONLOG(statement, @"formatted log text %d", param1);
* @endcode
*
* If statement is true, then the formatted text will be written to the log.
*
* @code
* NIDINFO/NIDWARNING/NIDERROR(@"formatted log text %d", param1);
* @endcode
*
* Will only write the formatted text to the log if NIMaxLogLevel is greater than the respective
* NID* method's log level. See below for log levels.
*
* The default maximum log level is NILOGLEVEL_WARNING.
*
* <h3>Turning up the log level while the app is running</h3>
*
* NIMaxLogLevel is declared a non-const extern so that you can modify it at runtime. This can
* be helpful for turning logging on while the application is running.
*
* @code
* NIMaxLogLevel = NILOGLEVEL_INFO;
* @endcode
*
* @ingroup NimbusCore
* @defgroup Debugging-Tools Debugging Tools
* @{
