Nothing different from what's been explained but in code, these are the available transitions:

typedef enum {
        UIViewAnimationTransitionNone,
        UIViewAnimationTransitionFlipFromLeft,
        UIViewAnimationTransitionFlipFromRight,
        UIViewAnimationTransitionCurlUp,
        UIViewAnimationTransitionCurlDown,
    } UIViewAnimationTransition;

Code (Put this in a callback like touchesEnded):

CGContextRef context = UIGraphicsGetCurrentContext();
[UIView beginAnimations:nil context:context];

[UIView setAnimationTransition: UIViewAnimationTransitionFlipFromLeft forView:[self superview] cache:YES];

// -- These don't work on the simulator and the curl up will turn into a fade -- //
//[UIView setAnimationTransition: UIViewAnimationTransitionCurlUp forView:[self superview] cache:YES];
//[UIView setAnimationTransition: UIViewAnimationTransitionCurlDown forView:[self superview] cache:YES];

[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationDuration:1.0];

// Below assumes you have two subviews that you're trying to transition between
[[self superview] exchangeSubviewAtIndex:0 withSubviewAtIndex:1];
[UIView commitAnimations];
