ios uiimageview 点击手势在动画期间不起作用

Question

我有一个 UIImageView 是动画的并且接收一个 UITapGestureRecognizer。问题是在动画时，点击手势区域不会随 View 移动。我可以点击 View 的原始位置并识别点击手势。任何人都知道如何在 View 移动而不是在其原始位置时识别水龙头？

编辑 1:这就是我设置点击手势识别器的方式:

UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(viewTapped:)];
    tapRecognizer.cancelsTouchesInView = YES;
    tapRecognizer.numberOfTapsRequired = 1;
    tapRecognizer.delegate = (id)self;
    [imageView addGestureRecognizer:tapRecognizer];
    imageView.userInteractionEnabled = YES;

自从我的动画持续几秒钟后，有没有办法让手势识别器在其路径上跟随我的 View ？我错过了设置吗？

编辑 2:这是我设置动画的代码:

    double width = backgroundImageView.frame.size.width;
    double height = backgroundImageView.frame.size.height;

    CGMutablePathRef path = CGPathCreateMutable();
    double startX = -imageView.frame.size.width;
    double startY = height/4;
    double endX = 3*width;
    double endY = 0;
    double duration = 40;
    CGPathMoveToPoint(path, NULL, startX, startY);
    CGPathAddLineToPoint(path, NULL, endX, endY);
    CAKeyframeAnimation *animation = [CAKeyframeAnimation animationWithKeyPath:@"position"];
    animation.duration = duration;
    animation.path = path;
    animation.repeatCount = HUGE_VALF;
    [imageView.layer addAnimation:animation forKey:@"theAnimation"];

Answer 1

对于任何感兴趣的人，我解决了我的问题。只需使用 NSTimer，检查并更新 UIImageView 的 frame 来自 presentation layer 通过:

CGRect viewLocation = [[[imageView layer] presentationLayer] frame];    
imageView.frame = CGRectMake(viewLocation.origin.x, viewLocation.origin.y, viewLocation.size.width, viewLocation.size.height);

在那之后，无论我的 ImageView 在哪里，触摸都会起作用:-)
