    Hey Nathan, playing with your FTAnimation code – good stuff, thanks! Seeing something strange and can’t figure it out. I was hoping you my have a thought. Using the Popin animation, popin and popout work find first time, then each following invocation fails to show the popin animation (also, the view isn’t displayed). But, I can click in the view (triggering the Popout), and the popout animation is shown. Any thoughts? Thanks in advance Nathan.

    Mike: Interesting behavior. I’m not sure exactly what’s happening. The animations all take over the hidden attribute on UIView to hide or show the view based on the type of animation. This is because the animations were originally designed as transitions. For example, after popOut is finished, the hidden attribute is set to YES right before your delegate selector (if there is one) is called. There might be some kind of race condition going on, but it’s hard to say.

    I can take a look at it if you can give me a small example.

    Thanks for taking the time to respond Nathan. It was user error; I was passing in a different key on the addAnimation: call. This led to the problems noted above. Great stuff Nathan – I appreciate you making this available to us.
