I’m pretty sure I can create a page flip effect using a series of PNGs to simulate the animation but is there a way to do it programmatically? Tried googling it and looking at Apple sample code but didn’t see anything addressing that particular animation.

    I’m assuming you mean for an iPhone, right?

    From the Apple API docs for UIView:

    + (void)setAnimationTransition:(UIViewAnimationTransition)transition forView:(UIView *)view cache:(BOOL)cache

    where UIViewAnimationTransition is defined as:

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

    UIViewAnimationTransitionCurlUp is what you are looking for. See those docs for information on how to start, set, and commit animations to views as well.
