UIView Block Animation Update Interval

Question

Is there some kind of update event when a block animation is animating? I'd like to check the frame bounds on every animation update to check if my uiview reached a certain position.

You can accomplish this by using animation blocks. Instead of updates, though, you'll have an "instructions block" that runs when an animation completes . Take a look at this SOF question: Multistage animation using blocks
