斯威夫特：終止應用程序由於未捕獲的異常「NSInvalidArgumentException」，原因是：無法識別的選擇發送到實例0x7fb179f12260'

-2

我正在開發一個簡單的應用程序，但問題卡住了我一個長長久久！斯威夫特：終止應用程序由於未捕獲的異常「NSInvalidArgumentException」，原因是：無法識別的選擇發送到實例0x7fb179f12260'

我嘗試過境模型SEGUE！

上面的一個功能是作爲UITextField行動，但是當我用它打開。崩潰！

另外一個可以打開的模型。沒有崩潰！

class showVerifyViewController: UIViewController { 


    @IBOutlet weak var verifyText: UITextField! 

    @IBAction func setNewPinText(sender: AnyObject) { 
     if verifyText.text == "zzz" { 
      let viewController:UIViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewControllerWithIdentifier("SetupPinViewController") as UIViewController 
      let navigationView = UINavigationController(rootViewController: viewController) 
      self.presentViewController(navigationView, animated: true, completion: nil) 
     } 
    } 

    @IBAction func showTest(sender: AnyObject) { 
     let viewController:UIViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewControllerWithIdentifier("SetupPinViewController") as UIViewController 
     let navigationView = UINavigationController(rootViewController: viewController) 
     self.presentViewController(navigationView, animated: true, completion: nil) 
    } 
}

謝謝您的意見！ – HungCLo

showVerifyViewController中沒有名爲「setNewPintext」的函數。 –

@Eiko不管正確的格式是什麼，你的編輯做出的堆棧跟蹤不可讀 –

該錯誤告訴您，您在SoftPin.showVerifyViewController上調用setNewPintext:，但該方法不存在。也許是一個錯字？也許這應該是setNewPinText（使用大寫T）?:

你的答案不是很理解。我設置了名爲verifyText的出口和一個名爲setNewPinText的函數。爲什麼該方法不存在？ – HungCLo

您可以使用與定義方式不同的名稱調用該方法。它似乎被稱爲'setNewPintext'（如'SoftPin.showVerifyViewController.setNewPintext（「something」）'，小寫't'）。但是如你所看到的那樣，它被定義爲'setNewPinText'（帶有一個大寫的'T'） – Daniel
