我是 Swift 的新手，我想知道如何关闭当前 View Controller 并转到另一个 View 。

我的 Storyboard 如下所示:MainMenuView -> GameViewController -> GameOverView。我想关闭 GameViewController 以转到 GameOverView，而不是 MainMenuView。

我在 MainMenuView 中使用以下代码:

@IBAction func StartButton(sender: UIButton) {
    let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)
    let nextViewController = storyBoard.instantiateViewControllerWithIdentifier("GameViewController") as! GameViewController
    self.presentViewController(nextViewController, animated:true, completion:nil)
    restGame()
}

在 GameViewController 中，我使用了这段代码，但它并没有关闭 GameViewController。

let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)
let nextViewController = storyBoard.instantiateViewControllerWithIdentifier("GameOverView") as! GameOverView
self.presentViewController(nextViewController, animated:true, completion:nil)

这是我的 GameOverView 代码:

class GameOverView: UIViewController{
    // save the presenting ViewController
    var presentingViewController :UIViewController! = self.presentViewController

    override func viewDidLoad() {
        super.viewDidLoad()

    }

    @IBAction func ReplayButton(sender: UIButton) {
        restGame()
        didPressClose()
    }
    @IBAction func ReturnMainMenu(sender: UIButton) {
        Data.GameStarted = 1
        self.dismissViewControllerAnimated(false) {
            // go back to MainMenuView as the eyes of the user
            self.presentingViewController.dismissViewControllerAnimated(false, completion: nil);
        }
       /* let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)
        let nextViewController = storyBoard.instantiateViewControllerWithIdentifier("MainScene") as! MainScene
        self.presentViewController(nextViewController, animated:true, completion:nil)*/

    }
    func restGame(){
        Data.score = 0
        Data.GameHolder = 3
        Data.GameStarted = 1
        Data.PlayerLife = 3.0
        Data.BonusHolder = 30
        Data.BonusTimer = 0
    }
    func didPressClose()
    {
        self.self.dismissViewControllerAnimated(true, completion:nil)
    }
    override func shouldAutorotate() -> Bool {
        return false
    }

    deinit{
        print("GameOverView is being deInitialized.");

    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Release any cached data, images, etc that aren't in use.
    }

    override func prefersStatusBarHidden() -> Bool {
        return true
    }


}

有什么建议吗？

最佳答案

你可以做的是让 GameOverView 呈现出来，毕竟当你呈现它时，GameViewController 在层次结构的下方，然后在你的 GameOverView 中 当您想关闭 GameOverView 时，运行以下代码关闭两者，如下所示:

@IBAction func ReturnMainMenu(sender: UIButton) {
    // save the presenting ViewController
    var presentingViewController: UIViewController! = self.presentingViewController

    self.dismissViewControllerAnimated(false) {
          // go back to MainMenuView as the eyes of the user
          presentingViewController.dismissViewControllerAnimated(false, completion: nil)
    }
}

当你想关闭GameOverView时需要调用上面的代码。
