I'm no core animation expert, but.
This...
// self is an NSWindow instance
CAAnimation *anim = [CABasicAnimation animation];
[anim setDelegate:self];
[self setAnimations:[NSDictionary dictionaryWithObject:anim
forKey:@"frame"]];
[[self animator] setFrame:NSMakeRect(0,0,0,0) display:YES];
... works perfectly in my app, calling the delegate methods and all.
All other things being equal, the only difference I see is that you
use [window animationForKey:@"frame"] whereas I create a new animation
and then add it to the window with [window setAnimations:...].
My *guess* would be that maybe windows don't instantiate default
animations until they're needed, whereas frames instantiate them at
init. So when you call [window animationForKey:@"frame"] you're
getting nil back. But that's just a guess. I really don't know
enough about it.
Bug? Feature? I don't know. But this could be a workaround, anyway.

Hi all,
I've been playing with CA and I tried to set up one my objects as
the delegate for the frame change animation for an NSWindow by using
the following code:
CABasicAnimation* anim = [window animationForKey:@"frame"];
anim.delegate = self;
[[window animator] setFrame:NSMakeRect(400, 500, 500, 500)
display:YES];
Using this, the window correctly animates but the delegate methods
(namely animationDidStop:finished: and animationDidStart:) for the
CAAnimation do not get called. When I use the exact same piece of
code for setting the delegate of view animations, the delegates do
get called.
Thanks,
