With Apple recommending block-based animation of UIImageViews, I'm not quite grasping how to take older frame-by-frame animation code like this:
NSArray *playerImagesRight = [NSArray arrayWithObjects: [UIImage imageNamed:@"p1.png"], [UIImage imageNamed:@"p2.png"],[UIImage imageNamed:@"p3.png"],[UIImage imageNamed:@"p4.png"],nil];
[playerImage setAnimationImages:playerImagesRight];
[playerImage setAnimationDuration:.5];
[playerImage setAnimationRepeatCount:-1];
[playerImage startAnimating];
and turn it into a block animation with the whole "[UIImageView beginAnimations:nil context:NULL]" routine?
I've been able to get basic transforms to happen (changing the location of the NSImage, for example), but can't figure out how to flip automatically between multiple image frames using this technique. The best I've been able to do so far is to use a counter and my animation timer to keep calling setImage. Surely there is a better way to do this that I'm just not getting?
Thanks.
