Does pop support keyframe animations?

[rsaunders100]

Apologies if I have missed something obvious.

I was wondering if there was an equivalent to CAKeyframeAnimation or if its possible to do using a custom animation?

Pop doesn't natively support keyframe animations. Since those are usually known and setup in advance, it might be a good choice to use CAKeyframeAnimation directly.

Another two options are to use multiple Pop animations (start each one after the previous finishes, or match the beginTime to the previous animation's duration) or to implement the animation curve manually with a POPCustomAnimation.

The best option depends on what you're trying to achieve, though.

Agree with @grp. Let us know if you have something in mind that prevents using CAKeyFrameAnimation.

I was looking at pop since it looked like it handled cancelling animation better than CoreAnimation. I have some existing keyframe animation code which can be canceled or redirected following user interaction, but the code is messy (query the presentation layer etc...) I was hoping to port over to pop to tidy things up. But its no big deal!

@rsaunders100 for the "redirected following user interaction" I have created something here. Where basically I query for the animation and change its toValue.

It'd worth having POPKeyframeAnimation just to have Pop's awesome completionBlocks! :)
