In the iPod app on the iPhone there is a UIBarButtonItem in the upper right toolbar that flips between the song and track listings for the album. When you select the button, the button itself does a flip animation.

Is there a way to do this with:

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

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

Do I need to make a UIBarButtonItem with initWithCustomView vs. initWithImage to achieve this?
