滑动手势，touchMove同时被调用？

Question

我想在SwipeGesture和TouchMoved中执行不同的操作。但两者都被调用 当我们刷卡时，请帮忙吗？

 Drecoginizer  = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(handleSwipeFromD:)];
Drecoginizer.direction = UISwipeGestureRecognizerDirectionDown;
[self.view addGestureRecognizer:Drecoginizer];

据我了解，如果此滑动位于圆圈之外，则不希望选择器对滑动手势作出反应。在这种情况下，在滑动选择器的开头，您应该检查滑动是否在圆圈上方是这样的：

CGPoint lClick = [recognizer locationOfTouch:0 inView:self.view];

    //Distance from the center of the circle to the taped point
    int lDistance = sqrt(pow(lClick.x - lCircleCenter.x, 2) + pow(lClick.y - lCircleCenter.y, 2));

    if ((int)lDistance > (int)lCircleRadius) {
        return;
    }

希望它可以帮到你
