使用滑动手势更改视图控制器

Question

我想使用滑动手势移动到使用正确方向的另一个视图控制器。你可以帮我吗？

@IBAction func right(_ sender: UISwipeGestureRecognizer) { 

    // what I must write here 

} 

Answer 1

只写一行代码 -

@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 
     } 
    } 


}
