How to make a Spinning animation in facebook/pop?

Question

I have been searching for the whole internet about how to make a Spinning animation with facebook POP animation.

With no luck that kPOPLayerRotation only supports "Flip X/Y" animation, but not "Spin" (like the rotate property in front-end CSS), can anybody know how to do this?

Answer 1

Try this:

Objective-C

POPSpringAnimation *rotateAnimation = [POPSpringAnimation animation];
rotateAnimation.property = [POPAnimatableProperty propertyWithName: kPOPLayerRotation];
rotateAnimation.toValue= @(M_PI/4); 

Swift

let rotateAnimation = POPSpringAnimation(propertyName: kPOPLayerRotation)
rotateAnimation?.toValue = Double.pi / 4
