iphone - Will sending -removeAllAnimations to a layer also propagate to all it's sublayers?

Question

I wonder if sublayer animations would continue to play if I send -removeAllAnimations to a parent layer.

Answer 1

As per the documentation for removeAllAnimations:

Remove all animations attached to the receiver.

You'll need to iterate through the sublayers and remove animations from them as well:

for (CALayer* layer in [containerLayer sublayers]) {
  [layer removeAllAnimations];
}
