I noticed iOS 5 introduced extra parameters and ways to detect when a view controller’s presentation animation is complete.
Is there any way to do this in earlier versions, such as iOS 4.x?
I have used presentModalViewController to present the controller and I noticed that you can’t call the dismiss method unless the animation has completed.
So how can I detect when the animation is complete so I can then dismiss it?
I just tried dismissing a modally presented VC, on viewDidLoad, viewWillAppear and viewDidAppear. No dice on the first two, but the dismiss works in viewDidAppear. (Kind of makes sense that that would get called after the animations are done).
And, you probably know this already, but in case you don’t: you don’t have to dismiss the modally presented VC from the VC that presented it. Your “wait for the network” VC can check the connection state in viewDidAppear, and dismiss itself if the connection is finished.
