I believe that what you’re looking for is UIViewAnimationTransitionCurlUp and UIViewAnimationTransitionCurlDown, two transition effects that can be applied when switching views. To produce the effect, you could use code like the following:

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:CURLANIMATIONDURATIONFORSWITCHINGVIEWS];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.view cache:YES];

[newlyVisibleController viewWillAppear:YES];
[previouslyVisibleController viewWillDisappear:YES];
[previouslyVisibleController.view removeFromSuperview];
[self.view addSubview:newlyVisibleController.view];
[previouslyVisibleController viewDidDisappear:YES];
[newlyVisibleController viewDidAppear:YES];

[UIView commitAnimations];
