How to find the present state of a property when an animation is stopped early?

[screwtape]

Hi,

I've set of a CAKeyframeAnimation, and that's fine. However, if the user touches the screen while the animation is happening, I want it to stop where it was. I can stop it, but it then has the final value, not the present value in the property.

How do I find the present value when I stop the animation?

Concurrent Frame Number animation with it?
noob solution but hey?

OK... this seems to work. I'm grabbing the transform from the presentation layer just before stopping the animation.

		CATransform3D tmpTransform = [[rotationLayer presentationLayer] sublayerTransform];
		[rotationLayer removeAnimationForKey:kAnimation];

Anyone with a better way? There's still room for inaccuracy in this.
