Improvements Part III• Smooth Layer Animation (CAKeyframeAnimation)

if( currentPosition.x != currentAnimatedPosition.x || currentPosition.y != currentAnimatedPosition.y ){

[animationLayer setPosition: currentAnimatedPosition];[animationLayer removeAnimationForKey:@__FILE__];

[animationArray insertObject: [NSValue valueWithCGPoint:currentAnimatedPosition] atIndex: 0];[animationArray insertObject: [NSValue valueWithCGPoint:currentPosition] atIndex: 1];

}else{

[animationArray insertObject: [NSValue valueWithCGPoint:currentPosition] atIndex: 0];

}...theAnimation.values = animationArray;theAnimation.duration = duration;theAnimation.delegate = self;[animationLayer addAnimation:theAnimation forKey:@__FILE__];
