如何向右滑动以在Swift 3中显示新的View Controller？

我想能够在我的ViewController ，将显示另一个视图控制器， CommunitiesViewController 。

我已经看了其他线程，发现了一些这样做，虽然我相信他们是斯威夫特2。

这是我在我的ViewController使用的代码：

 override func viewDidLoad() { super.viewDidLoad() let swipeRight = UISwipeGestureRecognizer(target: self, action: Selector(("respondToSwipeGesture"))) swipeRight.direction = UISwipeGestureRecognizerDirection.right self.view.addGestureRecognizer(swipeRight) } func respondToSwipeGesture(gesture: UIGestureRecognizer) { print ("Swiped right") if let swipeGesture = gesture as? UISwipeGestureRecognizer { switch swipeGesture.direction { case UISwipeGestureRecognizerDirection.right: //change view controllers let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil) let resultViewController = storyBoard.instantiateViewController(withIdentifier: "CommunitiesID") as! CommunitiesViewController self.present(resultViewController, animated:true, completion:nil) default: break } } } 

我给了CommunitiesViewController ID的故事板ID。

但是，这不起作用，当我刷一下以下错误的应用程序崩溃：

错误的select器格式，更改为：

 action: #selector(respondToSwipeGesture) func respondToSwipeGesture(gesture: UIGestureRecognizer) 

要么

 action: #selector(respondToSwipeGesture(_:)) func respondToSwipeGesture(_ gesture: UIGestureRecognizer) 

Answer 2

试试：

 override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view, typically from a nib. // Gesture Recognizer let swipeRight = UISwipeGestureRecognizer(target: self, action: #selector(self.respondToSwipeGesture)) swipeRight.direction = UISwipeGestureRecognizerDirection.right self.view.addGestureRecognizer(swipeRight) let swipeLeft = UISwipeGestureRecognizer(target: self, action: #selector(self.respondToSwipeGesture)) swipeLeft.direction = UISwipeGestureRecognizerDirection.left self.view.addGestureRecognizer(swipeLeft) } 

然后添加function：

 func respondToSwipeGesture(gesture: UIGestureRecognizer) { if let swipeGesture = gesture as? UISwipeGestureRecognizer { switch swipeGesture.direction { case UISwipeGestureRecognizerDirection.right: //right view controller let newViewController = firstViewController() self.navigationController?.pushViewController(newViewController, animated: true) case UISwipeGestureRecognizerDirection.left: //left view controller let newViewController = secondViewController() self.navigationController?.pushViewController(newViewController, animated: true) default: break } } }
