objective-c - AnimationDidStop 未被调用

Question

由于某种原因，我的animationDidStop方法没有被调用，最初我认为这是因为未设置委托(delegate)，但经过补救后我仍然遇到同样的问题。有任何想法吗？预先感谢:)

- (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

}

您可以通过使用the new (iOS4+) block syntax来实现您想要的:

[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
                 }];
