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

This is MT code of @Robert Ryan's technique (although I agree with his suggestion that theAppScreen is probably the "correct" RootViewController):

void DissolveIn (UIWindow window, UIViewController newController)
{
  newController.ModalTransitionStyle = UIModalTransitionStyle.CrossDissolve;
  window.RootViewController.PresentViewController (newController, true, () => 
  {
    window.RootViewController.DismissViewController (false, null);
    window.RootViewController = newController;
  });
}
