CABasicAnimation get value steps for 30
I've got a CABasicAnimation that is operating on the transform property of a CALayer. The animation looks fairly cool and it all works fine, but now I want to know through which values the transform of the layer is going to go through for a perfect 30/60 FPS animation.
I don't want to run the aniamtion and measure the values, I want to know beforehand.
The timingFunction has to be taken into account for this calculation.
How can I find out these transform values?
That's the animation code:
CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath: @"transform"];
animation.fromValue = [NSValue valueWithCATransform3D: _myLayer.transform];
animation.toValue = valueTransform;
animation.duration = 0.7;
animation.timingFunction = [CAMediaTimingFunction functionWithName: kCAMediaTimingFunctionEaseInEaseOut];
[_myLayer addAnimation: animation forKey:@"transformAnimation"];
