Question

我有一些UIImageViews，当用户触摸时，会启动具有特定持续时间的动画。触发器计数++，并且在下一次触摸时，另一个动画开始播放。但是如果用户触摸快速或进行双重触控，则第一个动画直到最后一帧才结束。我尝试了“sleep（）”命令，但它不起作用。

    #pragma mark HenneAnimation
    if([touch view] == ani_Henne){

        //trigger strats with zero
        switch (trigHenne) {
            case 0:
//firstanimation 1 sec
                ani_Henne.animationImages = [NSArray arrayWithObjects:
                                             [UIImage imageNamed:@"ani_Henne01.png"],
                                             [UIImage imageNamed:@"ani_Henne01.png"],
                                             [UIImage imageNamed:@"ani_Henne02.png"],
                                             [UIImage imageNamed:@"ani_Henne01.png"],
                                             [UIImage imageNamed:@"ani_Henne01.png"],nil];


                ani_Henne.animationDuration = 1;
                ani_Henne.animationRepeatCount = 1;
                [ani_Henne startAnimating];
                [self.view addSubview:ani_Henne];

                trigHenne++;
                break;

            case 1:
//second animation 1 sec                
                ani_Henne.animationImages = [NSArray arrayWithObjects:

Answer 1

当你开始设置动画时，禁用了userinteraction，当你完成后，重新启用它：

yourImageView.userInteractionEnabled = NO;

yourImageView.userInteractionEnabled = YES;

您还可以使用

延迟启用

...
[self performSelector:@selector(enable) withObject:yourImageView afterDelay:1.0];
...


-(void)enable
{
yourImageView.userInteractionEnabled = YES
}

Answer 2

使用UIApplications beginIgnoringInteractionEvents和endIgnoringInteractionEvents可能对您有所帮助，当调用begin时，将忽略来自用户的UI交互事件，这里是引用UIApplication ref

如何在允许下一个用户输入之前完成动画
