cancel a UIView animateWithDuration before completion

Question

I have this code in my project:

- (void) fadeImageView {
    [UIView animateWithDuration:1.0f
                          delay:0
                        options:         


        

Answer 1

From Apple docs: Use of this method is discouraged in iOS 4.0 and later. Instead, you should use the animateWithDuration:delay:options:animations:completion: method to specify your animations and the animation options.:

[UIView animateWithDuration:1.f
                      delay:0
                    options:UIViewAnimationOptionBeginFromCurrentState
                 animations:^{
                     self.imageView.alpha = 0.0f;
} completion:NULL];
