ios - 动画期间的 UITapGestureRecongnizer 失败

Question

我正在使用以下代码生成可触摸的图像。

我在这里看到一些帖子说 UIButton 不能在动画期间使用，所以我改为使用点击手势。我还在选项中添加了 UIViewAnimationOptionAllowUserInteraction。但我仍然无法让它发挥作用。我可以知道原因和任何解决方案吗？

hit1 = [[UIImageView alloc]initWithFrame:CGRectMake(539,227,50,50)];
hit1.image=[UIImage imageNamed:@"roles.png"];

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hitenermy:)];
[hit1 addGestureRecognizer:singleTap];
[hit1 setMultipleTouchEnabled:YES];
[hit1 setUserInteractionEnabled:YES];
hit1.userInteractionEnabled=YES;


[self.view addSubview:hit1];
[hit1 addGestureRecognizer:singleTap];
UIViewAnimationOptions options = UIViewAnimationCurveEaseInOut | UIViewAnimationOptionAllowUserInteraction;

[UIView animateWithDuration:15.0
                      delay:1.0
                    options:options
                 animations:^{
                     hit1.center = CGPointMake(hit1.center.x-210, hit1.center.y-60);

                 }
                 completion:^(BOOL finished){

                 }];

您可以使用 - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event 获取触摸事件。我已经展示了单个 imageView，但如果存在多个 imageView，那么您可以使用标签来区分它们。

您可以从:UIButton can't be touched while animated with UIView animateWithDuration 获得更多信息

- (void)viewDidLoad
    {
        [super viewDidLoad];

        hit1 = [[UIImageView alloc]initWithFrame:CGRectMake(539,227,50,50)];
        hit1.image=[UIImage imageNamed:@"roles.png"];

        [self.view addSubview:hit1];

        UIViewAnimationOptions options = UIViewAnimationCurveEaseInOut | UIViewAnimationOptionAllowUserInteraction;

        [UIView animateWithDuration:15.0
                              delay:1.0
                            options:options
                         animations:^{
                              hit1.center = CGPointMake(hit1.center.x-210, hit1.center.y-60);
                         }
                         completion:^(BOOL finished){

                         }];
    }



     - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
        {
            UITouch *touch = [touches anyObject];
            CGPoint touchLocation = [touch locationInView:self.view];
            for (UIImageView *imageView in self.view.subviews)
            {
                if ([imageView.layer.presentationLayer hitTest:touchLocation])
                {
                    NSLog(@"Clicked");
                    break;
                }
            }
        }
