如何在允许下一个用户输入之前让动画完成答案

【问题标题】：How to let an animation finish before the next userinput is allowed如何在允许下一个用户输入之前让动画完成

【问题描述】：

我有一些 UIImageViews，当用户触摸时，会启动一段持续时间的动画。触发器计数 ++，下一次触摸开始播放另一个动画。但是，如果用户快速触摸或进行双击，第一个动画直到最后一帧才会结束。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:

                                             [UIImage imageNamed:@"ani_Henne03.png"],

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

                trigHenne++;

                break;

            case 2:
                [self.view bringSubviewToFront:ani_Henne];

                ani_Henne.animationImages = [NSArray arrayWithObjects:

【解决方案1】：

当您开始设置动画时禁用用户交互，完成后重新启用它，如下所示：

yourImageView.userInteractionEnabled = NO;

yourImageView.userInteractionEnabled = YES;

你也可以延迟启用

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


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

谢谢！我今晚试试。
谢谢，它就像我想要的那样工作！它比 beginIgnoringInteractionEvents 解决方案更好更简单，因为只有选择的 View 被禁用输入！

【解决方案2】：

使用 UIApplications beginIgnoringInteractionEvents 和 endIgnoringInteractionEvents 可能会对您有所帮助，当调用 begin 时，来自用户的 UI 交互事件将被忽略，这是一个参考 UIApplication ref

【讨论】：

非常感谢您的提示！
我已经这样做了：案例0：[[UIApplication sharedApplication] beginIgnoringInteractionEvents]; [UIView beginAnimations:nil context:nil]; { [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; //geschmeidige Bewegeung [UIView setAnimationDuration:10.0f]; [UIView setAnimationDelegate: self]; ani_schwein_gross.transform = CGAffineTransformMakeTranslation (-200, 10); [UIView setAnimationDidStopSelector:@selector(doneSwappingViewsAnimation:finished:context:)]; } [UIView 提交动画];等动画结束 - 任何输入都被禁用。
在 ViewDIdLoad 我插入之前： - (void) doneSwappingViewsAnimation: (NSString*) id finished: (BOOL) finished context: (id) context { [[UIApplication sharedApplication] endIgnoringInteractionEvents]; }
