No. It is a CABasicAnimation, but it also works with a
CAKeyframeAnimation.
I modified the example project from this blog post: http://www.cimgf.com/2008/11/05/core-animation-tutorial-interrupting-animation-progress/
to demonstrate this. The modified project is here: http://www.cimgf.com/files/FollowMe.zip
.
The sample code does not actually call -removeFromSuperlayer as the
layer gets referenced again which would cause it to crash. Make sure
you're not accessing the layer again after you've removed it from it's
parent. Unless you've explicitly retained it, it's been autoreleased
at that point.

Hey,
Is the animation your own subclass of CAAnimation? I am justing using
CAKeyframeAnimation.

Bridger,
As far as I can tell there is nothing inherent in the CA API to do
what you
want, however, KVC is available to you. When you create your
animation, do
this:
[animation setValue:objectLayer forKey:@"parentLayer"];
Where objectLayer is the layer the animation is going to be run on.
Then,
in your -animationDidStop, you can grab the layer like this:
- (void)animationDidStop:(CAAnimation *)theAnimation finished:
(BOOL)flag
{
CALayer *layer = [theAnimation valueForKey:@"parentLayer"];
if( layer )
{
NSLog(@"The layer object was: %@ (%@)", layer, [layer name]);
[layer removeFromSuperlayer];
}
}
I named my layer when I created it with a call to [objectLayer
setName:@"parentLayer"]
in this code, so the NSLog in -animationDidStop won't display the
name
unless you've done the same.
Best regards,
-Matt
