ios - 我想快速左右滑动

Question

我在 xcode 7 ( swift ) 中有一个项目，我想加载在 Storyboard 中设计的不同 View Controller ，其功能是左右滑动，然后转到下一个 View Controller 或返回。现在我有了这个，但只从右到左淡入，我想要两个淡入。

func respondToSwipeGesture(sender: UISwipeGestureRecognizer) {

    switch sender.direction {
    case UISwipeGestureRecognizerDirection.Right:
        print("SWIPED DERECHA")
       self.performSegueWithIdentifier("cambio2", sender: nil)
    case UISwipeGestureRecognizerDirection.Left:
        print("SWIPED IZQUIERDA")
        self.performSegueWithIdentifier("cambio", sender: nil)
    default:
        break
    }
}

Answer 1

您还可以通过创建它的 2 个实例来使用 UISwipeGestureRecognizer。每个方向一个。

    var swipeLeft : UISwipeGestureRecognizer = UISwipeGestureRecognizer(target: self, action: "swipe:")
    swipeLeft.direction = UISwipeGestureRecognizerDirection.Left

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

    self.view.addGestureRecognizer(swipeLeft)
    self.view.addGestureRecognizer(swipeRight)

和滑动功能

func swipe(sender: UISwipeGestureRecognizer) {

    switch sender.direction {
    case UISwipeGestureRecognizerDirection.Right:
        print("SWIPED DERECHA")
        self.performSegueWithIdentifier("first", sender: nil)
    case UISwipeGestureRecognizerDirection.Left:
        print("SWIPED IZQUIERDA")
        self.performSegueWithIdentifier("second", sender: nil)
    default:
        break
    }
}
