cancel a UIView animateWithDuration before completion

I have this code in my project: ``` - (void) fadeImageView { [UIView animateWithDuration:1.0f delay:0 options:UIViewAnimationCurveEaseInOut animations:^{ self.imageView.alpha = 0.0f; } completion:^(BOOL finished) { //make the image view un-tappable. //if the fade was canceled, set the alpha to 1.0 }]; } ``` however, there are circumstance where i would like to cancel this operation before the imageview has become invisible. Is there a way to cancel this animation mid animation?
