AnimationDidStop不被称为

Question

我的animationDidStop方法没有被调用，出于某种原因，最初我以为是因为代理没有设置，但补救说，我仍然有同样的问题。有任何想法吗？在此先感谢:)

- (void)hideInterfaceButtonClicked : (id) sender 
{ 

[UIView setAnimationDelegate:self]; 
[UIView setAnimationDidStopSelector:@selector(animationDidStop)]; 

[UIView beginAnimations:@"MoveView" context:nil]; 
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn]; 
[UIView setAnimationDuration:0.5]; 

// Move to the right 
CGAffineTransform translateInterface = CGAffineTransformMakeTranslation(454,288); 
// Scale 
CGAffineTransform scale = CGAffineTransformMakeScale(0.20,0.20); 

// Apply them to the view 
self.transform = CGAffineTransformConcat(scale, translateInterface); 

self.alpha = 0.0; 

[UIView commitAnimations]; 

} 

- (void)animationDidStop { 

NSLog(@"Animation Has Stopped"); 
[[NSNotificationCenter defaultCenter] postNotificationName:@"hiddenInteraceViewNeeded" object:self]; //after MoveView finishes 

}

你可以实现你想要的使用the new (iOS4+) block syntax：

[UIView animateWithDuration:0.5 
         delay:0.0 
        options:UIViewAnimationCurveEaseIn 
       animations:^{ 
        // Move to the right 
        CGAffineTransform translateInterface = CGAffineTransformMakeTranslation(454,288); 
        // Scale 
        CGAffineTransform scale = CGAffineTransformMakeScale(0.20,0.20); 

        // Apply them to the view 
        self.transform = CGAffineTransformConcat(scale, translateInterface); 

        self.alpha = 0.0; 
       } completion:^(BOOL finished) { 
        NSLog(@"Animation Has Stopped"); 
        [[NSNotificationCenter defaultCenter] postNotificationName:@"hiddenInteraceViewNeeded" object:self]; //after MoveView finishes 
       }];
