What is the best or recommended technique for animating PNG Sequences.
Heres what I've learned:

Do it Manually
Using MutableArrays containing Strings, you can animate a UIImageView with a timer which increments an index number

UIImage - animation methods
This works, the only problem is to find if an image has completed its animation, you have to check the isAnimating BOOL, and to do that you need a timer.

What is the best and recommended?

Looking to do Oldschool game sprite animations, ie:

Idle Animation
Attack Animation
Walk Animation
ect...

Let me know if any one has something.
