FWIW: UIView sets the delegate of its CALayer to itself - one of the things
that it appears to do is to disable any implicit animations. If you add your
own CALayer to a UIView's CALayer, then you're in full control. As already
pointed out, it's easier using one of the UIView animation class methods to
animate UIView stuff... :)
> I use this code (iOS 5.1):
> CGAffineTransform m = { c, +s, -s, c, 0, 0 }; // rotation, s =
sin(angle), c = cos(angle)
> CALayer *layer = self.view.layer; // view is UIView, self is
subclass of UIViewController
> [ CATransaction begin];
> [ CATransaction setAnimationDuration: 9 ];
> [ layer setAffineTransform: m ];
> [ CATransaction commit];
