swipeGesture、touchMoved 被同时调用吗？

我想在 SwipeGesture 和 TouchMoved 中执行不同的操作。但是两者都被称为当我们刷卡时。有什么帮助吗？

 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，您不希望选择器对滑动手势做出反应。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，如下所示：

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;
    }

希望它对您有帮助

As I understood you do not want the selector to react on swipe gesture if this swipe is outside of the circle. In this case, in the beginning of the swipe selector you should check if the swipe is over the circle something like so:

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;
    }

Hope it helps you
