iOS animation experts! What are the pros and cons of each method? I know Apple recommends blocks instead of the old UIView animation methods (UIView beginAnimations, etc), but what about CAAnimation? When would you use one method vs the other? Is there a tradeoff in terms of performance?
1) There is not much difference in terms of memory expenses between UIView's animation blocks and CALayers's CAAnimation nor in terms of the objects themselves.
2) There are limitations to the type of animations you can achieve with UIView's animation, so you might be forced to use CAAnimation anyway.
3) For those types of simpler animations that UIView can handle, it is usually a simpler API to use than that of CAAnimation.
