Question

我有办法处理我在别处宣布的双轮wi:

-(void)handleDoubleSwipe:(UISwipeGestureRecognizer *)recognizer
{
    NSLog(@"double swiped");
    if(recognizer.direction==UISwipeGestureRecognizerDirectionLeft) {
        NSLog(@"swiped left");
     }
     if(recognizer.direction==UISwipeGestureRecognizerDirectionRight) {
         NSLog(@"swiped right");
     }

}

我宣布:

    UISwipeGestureRecognizer *doubleSwipe=[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleDoubleSwipe:)];
    doubleSwipe.numberOfTouchesRequired=2;
    doubleSwipe.delegate=self;
    doubleSwipe.direction=UISwipeGestureRecognizerDirectionRight | UISwipeGestureRecognizerDirectionLeft;

问题是,Im无法向甄选者提供任何参数。这只是让我去做,使我能够完成零件工作。我将如何在选择人的参数上添加双Swipe的姿态? 如今,操作的DoubleSwipe方法确实被叫去,国家行车监督记录仪显示的是“双血清”但确实显示左或右.。

Answer 1

The direction property of the recognitionr notess about the guidance (s) the recognitionr Hands (just as You configued it), not the guidance of the actual swipe.

您可使用<代码>所在地点在意见中: 方法与state 财产相结合,以确定 s草何时开始和结束。

通过为每一方向使用一台识别器可能比较容易。
