How do you explicitly animate a CALayer's backgroundColor?

Question

I\'m trying to construct a CABasicAnimation to animate the backgroundColor property of a Core Animation CALayer, but I can\'t figure out how to properly wrap a CGColorRef va

Answer 1

I was struggling with this problem until I experimentally found the roadblock. Setting the backgroundColor property of the layer, either directly or via the animation, will have no effect if you change the background color from the default (of unspecified) in Interface Builder, in the context of course of an item (such as UILabel) that's been placed in IB. So leave the background color unspecified and the above should work.
