Fixing animation snapback without setDisableActions:YES
View gist:11214298
// Implements the solution for solving "snapback" found in
// Chapter 8 of "iOS Core Animation Advanced Techniques" by Nick Lockwood
// without the need to use setDisableActions: to override the implicit animation,
// instead passing in the implicit animation key in addAnimation:forKey:
// With setDisableActions
- (void)applyBasicAnimation:(CABasicAnimation *)animation toLayer:(CALayer *)layer
//set the from value (using presentation layer if available)
animation.fromValue = [layer.presentationLayer ?: layer valueForKeyPath:animation.keyPath];
