Edit:
Did you try to call `[myView setNeedsDisplay];`?

Maybe there is one confusion: `viewDidLoad` is called right before you are presenting the view. Therefore in the code you have shown here `incrementaProgres:` is called before `viewDidLoad`. |

] | There might be a big problem with any checked-in bag. If this is all with the same airline, your bag might be checked through to destination C, with no opportunity to retrieve it at the intermediate stop B. | 1. It's unlikely but not impossible that you will get problems at check in. This can be interpreted as you cancelling the "B-C" leg, which incurs a change fee (as stated in the contract of carriage). It sounds insane, but airlines want you to pay for not taking a flight that you have already paid for. They can enforce ... |

] | No, there is no way to display a Flash file (SWF) in the iPhone browser.
If you have access to the source of the Flash files in the application, it may be possible to export them as HTML5 from the Flash builder. There's no way to do this conversion just from the SWFs, though.
