我想在UIView动画完成时执行动作。在UIView开始动画后完成动作完成

if (flipStateHav1 == 1 && btnFrontHav1.tag == 1) { 
    [UIView beginAnimations:nil context:nil]; 
    [UIView setAnimationDuration:0.8]; 
    [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:buttonContainerHav1 cache:YES]; 
    [self.buttonContainerHav1 bringSubviewToFront:btnBackHav1]; 
    [UIView commitAnimations]; 
    //It is this code below I want to run after the animation is finish. 
    buttonContainerHav1.userInteractionEnabled = YES; 
    flipTurns = 0; 
    flipStateHav2 = 0; 
    par = 0; 
}

我一直在使用

completion:^(BOOL finished){ 
    // your code 
}];

尝试，但没有得到它的工作，可能是我做错了什么。

更新代码 该按钮连接到两个操作。

- (IBAction) buttonPressedFlipHav1 { 
if (flipTurns == 0 || flipTurns == 1) { 
    flipTurns += 1; 
    [UIView beginAnimations:nil context:nil]; 
    [UIView setAnimationDuration:0.8]; 
     [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:buttonContainerHav1 cache:YES]; 
     [self.buttonContainerHav1 bringSubviewToFront:btnFrontHav1]; 
     buttonContainerHav1.userInteractionEnabled = NO; 
     flipStateHav1 = 1; 
     btnFrontHav1.tag = 1; 
     autoFlipCount += 1; 
     if (flipStateHav1 == 1 && flipStateHav2 == 1) { 
      par = 1; 
      parHav = 1; 
      btnFrontHav1.tag = 0; 
      btnFrontHav2.tag = 0; 
      flipTurns = 0; 
      autoFlipCount = 0; 
      if (parHav == 1 && parRiddare == 1 && parSkold == 1) { 
       autoFlipTimer = [NSTimer scheduledTimerWithTimeInterval:3.0f target:self selector:@selector(autoFlipAll) userInfo:nil repeats:NO]; 
      } 
     } 
    } completion:^(BOOL finished) { 
    NSLog(@"autoFlipCount = %d",autoFlipCount); 
    NSLog(@"Flipturns = %d",flipTurns); 
    }]; 
    } 
}

而且它也连接到这个动作。

- (IBAction) autoFlip { 
     autoFlipTimer = [NSTimer scheduledTimerWithTimeInterval:1.0f target:self selector:@selector(callAfterFiveSecond) userInfo:nil repeats:NO]; 
}

5秒后它跳到这个if语句。 更新

if (flipStateHav1 == 1 && btnFrontHav1.tag == 1) { 
    [UIView animateWithDuration:0.8 animations:^{ 
     [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:buttonContainerHav1 cache:YES]; 
     [self.buttonContainerHav1 bringSubviewToFront:btnBackHav1]; 
    } completion:^(BOOL finished) { 
     buttonContainerHav1.userInteractionEnabled = YES; 
     flipTurns = 0; 
     flipStateHav1 = 0; 
     par = 0; 
    }]; 
}

回答：

此代码可以帮助你

[UIView animateWithDuration:0.4 animations:^{ 
    //animation code here` 
} completion:^(BOOL finished) { 
     //code after animation here 
}];
