I'm hoping that all of the asterisks are just artifacts from a copy/
paste maneuver or something, however, if they are not then you're
missing some serious fundamentals. This code will never compile.
Let's just assume a copy/paste issue. If you are wanting to animate
the size of the frame, use the bounds property instead of frame.

Hi everyone.I am trying to create some animation when to change the
size of
a CALayer object.
My code looks like this:
CABasicAnimation * _animation =[CABasicAnimation animation].
[_animation setKeyPath:@"frame.size"];
NSSize _size;
*_size.**width** = 400**;*
*_size.**height** = 300**;*
*_animation.fromValue = [NSValue valueWithSize:_size];*
*_size.**width** = 200**;*
*_size.**height** = 150**;*
*_animation.toValue = [**NSValue** **valueWithSize**:_size];*
*[_layer **addAnimation**:_animation*
* **forKey**:_animationKey];*
However, the above code doesn't work at all. Can anyone tell me what
is
wrong with that? Or did I miss anything?
Thank you very much for any help or guidance.
Good luck.
