我是Swift的新手,我想知道如何解散当前的视图控制器并转到另一个视图。
我的故事板如下:MainMenuView-> GameViewController-> GameOverView。我想关闭GameViewController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,我使用此代码,但不会关闭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?
您可以做的就是GameOverView显示,毕竟,在显示它时,它GameViewController位于层次结构中的下面,然后在GameOverView运行时,当您要关闭时,下面的代码将两者都关闭GameOverView,就像这样:
GameOverView
GameViewController
@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) } }
要关闭时需要调用上述代码GameOverView。
希望对您有所帮助。
