Unfortunately this seems not to work either: an animation returned as an
action by e.g. actionForLayer:forKey: when hiding a layer (key @"hidden") is
never performed. So the workaround would presumably involve setting the
layer's opacity to 0.
What I would do, then, is something like this:
[CATransaction setCompletionBlock: ^{
[layer removeFromSuperlayer];
}];
[CATransaction setValue:@"" forKey:@"byebye"];
layer.opacity = 0;
Now in the delegate's actionForLayer:forKey: you test for the incoming
@"opacity" key and the CATransaction @"byebye" key, and if both conditions
are met, return the desired animation.
