UIView animation completion callback?

Question

Can I setup a function to be called once my animation is complete? I want to fade a UIView and then remove it from the superView.

Animation blocks were introduced in iOS4. Apple recommends you use these, and the new methods mostly ask for completion blocks which replace callbacks. For example:

[UIView animateWithDuration:0.5f
                      delay:0.0f
                    options:UIViewAnimationCurveEaseInOut
                 animations:^{
                   [myView setAlpha:0.0f];
                 }
                 completion:^(BOOL finished) {
                   [myView removeFromSuperview];
                 }];
