Animate UIButton state change

Question

I\'m using a UIButton with images for normal and highlighted states. They work as expected but I want to have some fading/merging transition and not just a sudden swap.

Answer 1

UIButton inherits from UIView

So then you get its view and call beginAnimations:context:

Then all the appropriate setAnimation methods from there.

The following properties of the UIView class are animatable:

• @property frame
• @property bounds
• @property center
• @property transform
• @property alpha
• @property backgroundColor
• @property contentStretch
