2016-01-19 23:21：15.132 Test2 [86049：25427867] ***由於未捕獲異常'NSInvalidArgumentException'，原因：'Receiver（）沒有標識符'gameSegue'

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 
    if segue.identifier == "gameSegue"{ 
     let gameViewController = segue.destinationViewController as! GameViewController 
     gameViewController.performSegueWithIdentifier("gameSegue", sender: gameViewController) 
    } 
} 

    viewController = MainMenuViewController() 
    let segue = UIStoryboardSegue(identifier: "gameSegue", source: MainMenuViewController(), destination: GameViewController()) 
    viewController.prepareForSegue(segue, sender: self) 

我得到上面每當我打電話prepareForSegue功能

Answer 1

的錯誤更換

let gameViewController = segue.destinationViewController as! GameViewController 
gameViewController.performSegueWithIdentifier("gameSegue", sender: gameViewController) 


viewController = MainMenuViewController() 
let segue = UIStoryboardSegue(identifier: "gameSegue", source: MainMenuViewController(), destination: GameViewController()) 
viewController.prepareForSegue(segue, sender: self) 

隨着

let detailedView = GameViewController() 
    if let detailedView = segue.destinationViewController as? GameViewController { 
     // Do whatever passing of parameters here.   
    } 

將segue代碼添加到您要調用的位置。

performSegueWithIdentifier("gameSegue", sender: nil) 

Answer 2

的代碼似乎表明，你想要麼兩個級聯塞格斯（與兩個控制器相同的名稱），或者你正試圖重定向到一個不同的控制器。

這真的是你想要做的嗎？

currentController - >「gameSegue」 - > gameViewController - >「gameSegue」 - > ???

當觸發segue時（例如從故事板），prepareForSegue和performSegueWithIdentifier都會自動調用。你不必自己調用performSegueWithIdentifier。
