Thanks for the response

A CALayer does not respond to gesture events. If I want to display an image that responds to user interaction and also animate it is UIView animation my only option?

Thanks

Correct. And that difference is the reason. You cannot use implicit
property animation on a view's primary layer.

Correct. Think of a UIView as a CALayer plus touch handling.

No. You can't use implicit property animation. But you can use explicit Core Animation.

I've explained the whole thing here:
