Re: Custom CALayer Action as animation key?

Patrick, I believe the only animatable properties are the ones explicitly labeled "animatable" in the documentation. That is why (I believe) there is a section labeled "Animatable Properties" in the Core Animation Programming guide. I think the reason is that you can't guarantee that your
