我要做“猜对牌”游戏，即：窗口中有24张卡片（UIImageView），隐藏在视图显示表面，它们是12组数字，你触摸一个，然后它会在里面打开显示，找到如果打开了同一张卡，如果不匹配，则两张打开的卡将隐藏。

只是这个。

打开卡片和隐藏卡片动作使用 UIView 动画。但是现在我有一个问题。当我触摸卡片时，它会尝试查找是否有匹配项。但是开卡和关卡动作动画是同时执行的。连我看清楚的卡片内容都看不清楚。

我想在触摸后打开一张卡片，然后（甚至等待 0.5 秒）同时关闭打开的不匹配的卡片。不能同时开卡和关卡。但是在下面的代码中，我确实先打开了一张卡，然后计算，然后关闭了两张打开的卡。

@interface Card : UIImageView

@property BOOL expanded;
@property BOOL found;
@property (retain)NSString * nameTitle;
@property (retain) UIImage * expandedImage;

@end

更新：我关注了 Kashiv，这个更新的代码：

- (void)openCard{
    NSLog(@"open card");
    if(cardAnimationIsActive) return;
    cardAnimationIsActive = YES;


    if (self.expanded){return;}
    self.expanded = YES;


    [UIView animateWithDuration:2.0f animations:^{


        [UIView beginAnimations:@"animation1" context:nil]; 
        [UIView setAnimationDuration:0.8];
        [UIView setAnimationDelegate:self];

        [UIView setAnimationBeginsFromCurrentState:YES];
        [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self cache:YES];
        [self setTransform:CGAffineTransformMakeScale(3.0, 3.0)];
        [self setImage:self.expandedImage];
        [UIView commitAnimations];

        [UIView beginAnimations:@"animation1_open" context:nil]; 
        [UIView setAnimationDuration:1.2];
        [UIView setAnimationDelegate:self];

        [UIView setAnimationBeginsFromCurrentState:NO];
        [self setTransform:CGAffineTransformMakeScale(1, 1)];
        [UIView commitAnimations];



    } completion:^(BOOL finished){
        cardAnimationIsActive = NO;
    }];




}

- (void)closeCard{

    if(cardAnimationIsActive) return;
    cardAnimationIsActive = YES;

    if (!self.expanded){return;}
    self.expanded = NO;

    [UIView animateWithDuration:5.0f animations:^{
        [UIView beginAnimations:@"animation1_close" context:nil]; 
        [UIView setAnimationDuration:0.8];
        [UIView setAnimationDelegate:self];


        [UIView setAnimationBeginsFromCurrentState:YES];
        [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self cache:YES];
        [self setTransform:CGAffineTransformMakeScale(3.0, 3.0)];
        [self setImage:[UIImage imageNamed:@"android_48.png"]];
        [UIView commitAnimations];

        [UIView beginAnimations:@"animation2_close" context:nil]; 
        [UIView setAnimationDuration:1.2];
        [UIView setAnimationDelegate:self];


        [UIView setAnimationBeginsFromCurrentState:NO];
        [self setTransform:CGAffineTransformMakeScale(1, 1)];
        [UIView commitAnimations];
        [self setUserInteractionEnabled:YES];
    } completion:^(BOOL finished){
        cardAnimationIsActive = NO;
    }];




}

但是 opencard 和 closecard 动画仍然同时执行。

你可以使用：

[UIView setAnimationDelay:delay];

将所有动画延迟到适当的时间，以便它们按顺序运行。

[UIView animateWithDuration:0.2 动画：^{view.alpha = 0.0;} 完成：^(BOOL 完成){ [view removeFromSuperview]; }];

您可以在完成块中创建第二个动画。

您可以通过使用基于块的动画来实现这一点：

+ (void)animateWithDuration:(NSTimeInterval)duration animations:(void (^)(void))animations completion:(void (^)(BOOL finished))completion

BOOL然后您可以使用iVar（例如）检查动画是否仍在执行或已完成cardAnimationIsActive。

例子：

- (void)openCard {
    if(cardAnimationIsActive) return;
    cardAnimationIsActive = YES;
    [UIView animateWithDuration:duration animations:^{
        --- your open animations ---
    } completion:^(BOOL finished){
        cardAnimationIsActive = NO;
    }];
}

- (void)closeCard {
    if(cardAnimationIsActive) return;
    cardAnimationIsActive = YES;
    [UIView animateWithDuration:duration animations:^{
        --- your close animations ---
    } completion:^(BOOL finished){
        cardAnimationIsActive = NO;
    }];
}
