使用滑动手势更改视图控制器

Question

我想使用滑动手势使用正确的方向移动到另一个视图控制器。你能救我吗？

@IBAction func right(_ sender: UISwipeGestureRecognizer) {

    // what I must write here

}

Answer 1

只需编写一行代码 -

@IBAction func right(_ sender: UISwipeGestureRecognizer) {

     if let swipeGesture = gesture as? UISwipeGestureRecognizer {
        switch swipeGesture.direction {
        case UISwipeGestureRecognizerDirection.right:

          self.performSegueWithIdentifier("nextView", sender: self)

          break
        default:
            break
        }
    }


}
