Custom view that sits on top of a UIImageView? Implement -drawRect: and a progress property and you're done.

I'd like to dynamically fill this button in an arc to show "progress" much like how when you are on iTunes Store on an iOS and its playing the preview its animating filling the circle in a sweep of an arc. Mine doesn't need to animate however.

That seems like it would get slow if I needed to do that a lot. Any suggestions? I also wouldn't mind any links that might show similar code. This is for iOS. I tried searching Google, but my GoogleFu is not showing anything, probably due to me not using the right terms.
