I've looked at the methods for block based animation and noticed there is no equivalent parameter or option for [UIView setAnimationRepeatCount:].
What's the simplest way to repeat an animation a fixed number of times? Do you, for instance, chain them using the completion block?
回答1:
Set a completion callback - re-initiate the animation in it - and keep track of the counter yourself.

I just asked a similar question and then I read the 2010-11-15 release of the View Programming Guide for iOS. Page 64 caught my attention.
In the animation block, one can still use the [UIView setAnimationRepeatCount:]. I thought that I could/should not. So my ability to read Apple doc needs to improve.
So perhaps this would solve your (and my need). I'm trying it later today

As @PommeOuest mentioned. You can still user [UIView setAnimationRepeatCount:] inside the animation block. I just tried in my project and it works well.
I'm using XCode4 and iOS5.
