【问题描述】：

如何在几秒钟后自动停用我的 UILongPressGestureRecognizer？

【参考方案1】：

在 -viewDidLoad 中设置时间间隔：

NSTimer *timer = [NSTimer scheduledTimerWithTimeInterval:5.0f target:self selector:@selector(removeGesture) userInfo:nil repeats:NO];

在选择器方法中：

-(void)removeGesture

    [self.view removeGestureRecognizer:longGesture1];

5 秒后，UILongPressGestureRecognizer 从视图中移除并停用

【参考方案2】：

检查一下：

[self performSelector:@selector(onTick:) withObject:nil afterDelay:2.0/*your delay time*/];


-(void)onTick:(id)sender

    for (UIGestureRecognizer *recognizer in self.view.gestureRecognizers)        

         if([recognizer isKindOfClass:[UILongPressGestureRecognizer class]])      
                  [self removeGestureRecognizer:recognizer];
          
   

希望这会有所帮助。
