Question

i got the following code:

test.image = [testArray lastObject];
test.animationImages = testArray;
test.animationDuration = 1;
test.animationRepeatCount = 1;
[test startAnimating];

I am sure that one day i read that it is possible to “rewind” an animation but i can’t find that solution any more – is there a better solution than ordering (DESC) the array?

Thanks!

You can reverse the animation by accessing the reverseObjectEnumerator’s objects:

testArray = [[testArray reverseObjectEnumerator] allObjects];

You can then pass that into the animation:

test.image = [testArray lastObject];
test.animationImages = [[testArray reverseObjectEnumerator] allObjects];
test.animationDuration = 1;
test.animationRepeatCount = 1;
[test startAnimating];

Or you could look into UIViewAnimationOptionAutoreverse, but i’m not sure that it’s entirely what you’re looking for.
