UISwipeGestureRecognizer -使用2个手指和3个手指滑动执行操作- iOS

Question

如何在同一视图上检测UISwipeGestureRecognizer 2或3手指轻扫- iOS

有谁知道吗？

Answer 1

这里的"setMinimumNumberOfTouches“取决于你的手指(例如:2/3/4/5)。一旦..it对您有所帮助，请立即尝试

  UIPanGestureRecognizer *pan;
 pan = [[UIPanGestureRecognizer alloc] initWithTarget:self     action:@selector(Swipe4ScrollViews:)];
[pan setMinimumNumberOfTouches:2];
 [_scroll1 addGestureRecognizer:pan];
  [pan release];

Answer 2

我已经创建了一个用于2和3个手指滑动的手势。

       func addTwoFingerSwipeGesture() {
            let gesture = UISwipeGestureRecognizer(target: self, action: "handleTwoFingerSwipe")
            gesture.direction = .Left
            gesture.numberOfTouchesRequired = 2 // 2 finger swipe
            self.view.addGestureRecognizer(gesture)
        }

       func addThreeFingerSwipeGesture() {
            let gesture = UISwipeGestureRecognizer(target: self, action: "handleThreeFingerSwipe")
            gesture.direction = .Left
            gesture.numberOfTouchesRequired = 3 // 3 finger swipe
            self.view.addGestureRecognizer(gesture)
        }


    // Handle Swipe
        func handleTwoFingerSwipe() {
            print("2 finger swipe recognized")
        }

        func handleThreeFingerSwipe() {
            print("3 finger swipe recognized")
        }
