我目前正在製作一款遊戲,當用戶輸了第二個ViewController
時,這是我的GameOverViewController
。Swift iOS - unwind segue崩潰
我已經成功設置了第二個視圖控制器,並且一旦加載了GameOverViewController
,幾乎立即運行插頁式廣告,然後replay
按鈕僅在插頁式廣告已關閉後纔會啓用。
我的應用程序崩潰,一旦重播按鈕被按下,它好工作之前,我加入了延遲,所以我猜測它的東西與我的新代碼。重放按鈕正在執行放鬆繼續(或試圖),任何人都可以幫助解決?
class GameOverViewController: UIViewController {
@IBOutlet weak var button: UIButton!
}
override func viewDidLoad() {
super.viewDidLoad()
self.button.enabled = false
NSTimer.scheduledTimerWithTimeInterval(3, target: self, selector: "enableButton", userInfo: nil, repeats: false)
//lots of code here to bring up google interstitial advert
}
func enableButton() {
self.button.enabled = true
}
按鈕正確灰色三秒鐘,然後變成藍色,但是一旦點擊的viewController掛起然後崩潰。該錯誤引發了帶有SIGABRT錯誤的AppDelegate。這是從輸出字段提取物...

這裏是我的GameViewController代碼,目前關於退卷在此ViewController
@IBAction func replay(segue: UIStoryboardSegue) {
}
任何幫助就沒有其他代碼萬分感謝。
您可以發佈控制檯的完整輸出嗎?你展示的這些線條並不是完全有用的。 – Stuart
@Stuart我已經爲您複製了完整的輸出,謝謝。 –
你在哪裏設置了'button'動作? –
