uiview 애니메이션 didendselector : 메소드가 호출되지 않습니까?

Question

시야로 이동하는 uiview가 있습니다. 2 초 후에는 UIView를 다시 시야로 옮기고 싶습니다. 어떻게해야합니까? 나는 아래를 시도했지만 작동하지 않습니다 :(

NSLOG를 설정했지만 마무리하는 것처럼 보이지는 않습니다. loadingViewDisappear: 방법 :(

고맙습니다.

...
    [UIView beginAnimations:@"AnimateIn" context:nil];
    [UIView setAnimationCurve: UIViewAnimationCurveEaseOut];
    [UIView setAnimationDuration: 0.7f];
    [UIView setAnimationDidStopSelector:@selector(loadingViewDisappear:finished:context:)];
    loadingView.frame = CGRectMake(rect.origin.x, rect.origin.y - 80, rect.size.width, rect.size.height);
    [UIView commitAnimations];
}

- (void)loadingViewDisappear:(NSString *)animationID finished:(NSNumber *) finished context:(void *) context {
    NSLog( (finished ? @"YES!" : @"NO!" ) );
    if ([animationID isEqualToString:@"AnimateIn"] && finished) {
        [UIView beginAnimations:@"AnimateOut" context:nil];
        [UIView setAnimationCurve: UIViewAnimationCurveEaseIn];
        [UIView setAnimationDelay:2.0f];
        [UIView setAnimationDuration: 0.7f];
        loadingView.frame = CGRectMake(0, 480, 320, 80);
        [UIView commitAnimations];
        [loadingView removeFromSuperview];
    }
}

애니메이션 대의원을 설정해야합니다.

[UIView beginAnimations:@"AnimateIn" context:nil];
[UIView setAnimationCurve: UIViewAnimationCurveEaseOut];
[UIView setAnimationDuration: 0.7f];

//Add this
[UIView setAnimationDelegate:self];

[UIView setAnimationDidStopSelector:@selector(loadingViewDisappear:finished:context:)];
loadingView.frame = CGRectMake(rect.origin.x, rect.origin.y - 80, rect.size.width, rect.size.height);
[UIView commitAnimations];
