我已经安装了的NSLog,但它并不像它完成,然后调用loadingViewDisappear:
方法:(
谢谢。
...
[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];
}
}
答
您需要设置动画的委托:
[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];
