ios - uilongpressgesturerecognizer 只触发一次

Question

我想添加一个手势，只有当一个人按下一秒钟左右时才会触发。不是轻按，而是长按。如果我使用 uilongpressgesturerecognizer，它会一直发射，直到我松开手指。我该如何解决这个问题。

Answer 1

在创建和添加手势时设置minimumPressDuration，如下所示:

UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizer alloc]
                                                      initWithTarget:self action:@selector(handleLongPress:)];
longPress.minimumPressDuration = 1.0;

在 UIGestureRecognizerStateEnded 状态下编写代码，如下所示:

-(void)handleLongPress:(UILongPressGestureRecognizer *)Gesture{

    if (Gesture.state == UIGestureRecognizerStateEnded) {


       //Do any thing after long press ended,which will be 1.0 second as set above


    }
    else if (Gesture.state == UIGestureRecognizerStateBegan){



    }
}
