iphone - 点击手势 + 长按手势都不能一起工作

Question

我想在 View 中同时使用点击手势和长按手势。但我的问题是我无法在点击时运行点击手势操作。但长按手势工作正常。

这是代码片段。

            UILongPressGestureRecognizer *longPressGesture=[[UILongPressGestureRecognizer alloc]initWithTarget:self action:@selector(ontappLongPressGesture:)];
            longPressGesture.minimumPressDuration=0.6;

            longPressGesture.delegate=self;
            [cell.view addGestureRecognizer:longPressGesture];

            UITapGestureRecognizer *gesture=[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(cellSelected:)];
            //[gesture requireGestureRecognizerToFail:longPressGesture]; //I have tried with this line also but not working
            gesture.delegate=self;
            [cell.view addGestureRecognizer:gesture];

我也设置了委托(delegate)方法

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

这个方法在长按时被调用

- (void)ontappLongPressGesture:(id)sender{

    //Long press code here

}

但是这个方法不会在点击时被调用

-(void)cellSelected:(id)sender {

     //Single tap code here

}

您没有指定将这些 gestureRecognizer 放在什么类型的 View 上，但是由于您称它为“单元格”，我假设它在 UITableView 上？

如果是这样，您需要确保设置了 cancelsTouchesInView 标志:

gesture.cancelsTouchesInView=NO;
