iPhone: Fade transition between two RootViewControllers

Question

Obj-C or MonoTouch C# answers are fine.

The initial UIWindow\'s RootViewController is a simple login screen.

window.RootViewCon         


        

Answer 1

You can do this:

window.RootViewController = theAppScreen;

loginScreen.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[theAppScreen presentModalViewController:loginScreen animated:NO];

loginScreen can dismiss itself when done: [self dismissModalViewControllerAnimated:YES];

The NO on the first animation will make the loginScreen appear without any visibility of the theAppScreen beneath it. The animated = YES on completion will provide the cross-dissolve.
