Question

I have a setter method for a property on a custom UIView class. If it’s set within a UIView animation block, I’d like it to add a CABasicAnimation to the view’s layer with the same duration and easing as the UIView animation. How do I find out whether I’m inside a UIView animation block, and how do I get its duration and easing curve?

Answer 1

Based on this question I made this extension to UIView block animations: UIView+AnimatedProperty.

It allows you to run CAAnimations when the setter is called from animation block. Example with cornerRadius is included.
