【问题描述】：

在我的项目中，我需要一个左右移动的滑动手势动作，我需要一个上下方向的平移手势动作。当我同时使用两个手势时，只有平移手势在调用。有人对此有解决方案吗？

 UISwipeGestureRecognizer *rightSwipe = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(goToPreviosSong)];
rightSwipe.direction = UISwipeGestureRecognizerDirectionRight;
[self.view addGestureRecognizer:rightSwipe];

UISwipeGestureRecognizer *leftSwipe = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(goToNextSong)];
rightSwipe.direction = UISwipeGestureRecognizerDirectionLeft;
[self.view addGestureRecognizer:leftSwipe];

对于 pan 我正在使用此代码

UIPanGestureRecognizer *panGesture = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(panAction:)];
[self.view addGestureRecognizer:edgePanGesture];

【参考方案1】：

[panGesture requireGestureRecognizerToFail:rightSwipe];
[panGesture requireGestureRecognizerToFail:leftSwipe];

【参考方案2】：

如果其他手势识别器没有执行，请使用requireGestureRecognizerToFail: 来识别手势。

[rightSwipe requireGestureRecognizerToFail: panGesture];
[leftSwipe requireGestureRecognizerToFail: panGesture];
