How to make animation animation UIBarButtonItem?

Question

The iPod app on iPhone has a UIBarButtonItem element in the upper right toolbar that scrolls through songs and track lists for an album. When you select a button, the button itself performs flip animation.

Is there any 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 create a UIBarButtonItem with initWithCustomView and initWithImage to achieve this?
