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 value to pass to the animation. For example: CGColorSpaceRef rgbColorspace = CGColorSpaceCreateDeviceRGB(); CGFloat values[4] = {1.0, 0.0, 0.0, 1.0}; CGColorRef red = CGColorCreate(rgbColorspace, values); CGColorSpaceRelease(rgbColorspace); CABasicAnimation *selectionAnimation = [CABasicAnimation animationWithKeyPath:@"backgroundColor"]; [selectionAnimation setDuration:0.5f]; [selectionAnimation setToValue:[NSValue valueWithPointer:red]]; [layer addAnimation:selectionAnimation forKey:@"selectionAnimation"]; seems to do nothing to the backgroundColor property, I assume because handing it off as a pointer wrapped in an NSValue is not the way to pass it along. backgroundColor is an animatable property of CALayer, so my question is: how do you set the From or To values for this particular property (preferably in a Mac / iPhone platform-independent way)?
