Animation groups

[naftaly]

Simple implementation of animation groups.

Use it as follows:

CALayer *layer = [CALayer layer];
POPGroupAnimation *group = [POPGroupAnimation animation];

POPBasicAnimation* anim1 = [POPBasicAnimation animationWithPropertyNamed:kPOPLayerBorderWidth];
anim1.toValue = @(5);
anim1.duration = 5;

POPBasicAnimation* anim2 = [POPBasicAnimation animationWithPropertyNamed:kPOPLayerCornerRadius];
anim2.toValue = @(20.0);
anim2.duration = 2;

group.animations = @[ anim1, anim2 ];

[layer pop_addAnimation:group forKey:@"group"];

Animations will run following the rules of the group ( pause, repeat, etc, ... ). Blocks and delegates will continue to function as they always have for the animations that are part of the group as well as the animation group.

The animation group completes only after all it's child animations are completed.
