滑动手势无法在IOS中使用UIView

Question

    UISwipeGestureRecognizer *rightRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(rightSwipeHandle:)];
rightRecognizer.direction = UISwipeGestureRecognizerDirectionRight;
[rightRecognizer setNumberOfTouchesRequired:1];
[self.view addGestureRecognizer:rightRecognizer];

UISwipeGestureRecognizer *leftRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(leftSwipeHandle:)];
leftRecognizer.direction = UISwipeGestureRecognizerDirectionLeft;
[leftRecognizer setNumberOfTouchesRequired:1];
[self.view addGestureRecognizer:leftRecognizer];

我在viewDidLoad方法上添加了滑动手势,我有多个视图左右滑动,视图包含表格,当表格有数据时,左右手势工作正常,但是在空表格手势不起作用的情况下.

有什么建议..？

注意:它在模拟器中工作,但在设备上不工作.

问题可能是因为我添加了两个手势,最后一位代表帮助了我.现在代码正在运行.

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
     { 
        return YES; 
     }
