标题: ios - 如何在表格 View 中访问手指位置/移动信息？

所以我想要做的是让我的表格 View 中的每个单元格都能够向左或向右滑动。如果我可以捕获手指位置/翻译，我可以更改内容的 x anchor 和 bingo bango，但我很难弄清楚。如果有人可以提供帮助，那就太好了

您可以查看有关 UISwipeGestureRecognizer 的苹果文档，默认方向是右，也可以探索此功能 UISwipeGestureRecognizerDirection 它返回您的方向是右，左，上，或底部。这里是演示

var swipeRight = UISwipeGestureRecognizer(target: self, action: "respondToSwipeGesture:")
swipeRight.direction = UISwipeGestureRecognizerDirection.Right
self.view.addGestureRecognizer(swipeRight)

var swipeDown = UISwipeGestureRecognizer(target: self, action: "respondToSwipeGesture:")
swipeDown.direction = UISwipeGestureRecognizerDirection.Down
self.view.addGestureRecognizer(swipeDown)

func respondToSwipeGesture(gesture: UIGestureRecognizer) {

if let swipeGesture = gesture as? UISwipeGestureRecognizer {


    switch swipeGesture.direction {
        case UISwipeGestureRecognizerDirection.Right:
            print("Swiped right")
        case UISwipeGestureRecognizerDirection.Down:
            print("Swiped down")
        case UISwipeGestureRecognizerDirection.Left:
            print("Swiped left")
        case UISwipeGestureRecognizerDirection.Up:
            print("Swiped up")
        default:
            break
    }
}

}
