的UIButton曹景偉崩潰

我有一些UIButtons當我加載視圖控制器應用crashs，當我刪除UIbuttons應用工程和負載的UIButton曹景偉崩潰

這是發生了什麼

下面是代碼

import UIKit 

class ViewController: UIViewController { 


    @IBOutlet var live: mainbutton! 

    @IBOutlet var dt: mainbutton! 

    @IBOutlet var ms: mainbutton! 
    @IBOutlet var `as1`: mainbutton! 
    @IBOutlet var read: mainbutton! 
    @IBOutlet var pg: mainbutton! 


    override func viewDidLoad() { 
     super.viewDidLoad() 


     self.view.backgroundColor = color125 

     live.setTitle("Live", forState: UIControlState.Normal) 
     dt.setTitle("Dhamma Talk", forState: UIControlState.Normal) 
     ms.setTitle("Mediations Stream", forState: UIControlState.Normal) 
     as1.setTitle("Adavanced And Special Streams", forState: UIControlState.Normal) 
     read.setTitle("Read", forState: UIControlState.Normal) 
     pg.setTitle("Program Guide", forState: UIControlState.Normal) 


     // Do any additional setup after loading the view, typically from a nib. 
    } 

    override func didReceiveMemoryWarning() { 
     super.didReceiveMemoryWarning() 
     // Dispose of any resources that can be recreated. 
    } 


}

應用代表

import UIKit 

@UIApplicationMain 
class AppDelegate: UIResponder, UIApplicationDelegate { 

    var window: UIWindow? 

    func grabStoryboard() -> UIStoryboard { 
     var storyboard = UIStoryboard() 
     let height = UIScreen.mainScreen().bounds.size.height 

     if height == 480 { 
      storyboard = UIStoryboard(name: "main3.5", bundle: nil) 
     } else if height == 568 { 
      storyboard = UIStoryboard(name: "main4", bundle: nil) 
     } else if height == 667 { 
      storyboard = UIStoryboard(name: "main6", bundle: nil) 
     } else if height == 736 { 
      storyboard = UIStoryboard(name: "main6plus", bundle: nil) 
     } else { 
      storyboard = UIStoryboard(name: "Main", bundle: nil) 
     } 

     return storyboard 
    } 

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { 
     // Override point for customization after application launch. 


    UINavigationBar.appearance().barTintColor = color125 


     let storyboard: UIStoryboard = self.grabStoryboard() 

     self.window?.rootViewController = 
      storyboard.instantiateInitialViewController()! as UIViewController 
     self.window?.makeKeyAndVisible() 
     return true 
    }

分

海關類代碼

override func awakeFromNib() { 
     self.backgroundColor = color125 
     self.layer.cornerRadius = 5 
     self.setTitleColor(UIColor.blackColor(), forState: .Normal) 
}

我覺得這行是罪魁禍首 -

@IBOutlet var `as1`: mainbutton!

刪除這些報價

@IBOutlet var as1: mainbutton!

該錯誤消息表示，他們是一個缺失的環節以獲得出口其名稱是「one」（「關鍵之一」）。

2016年1月17日16：27：51.151 HHKNBK [36147：32655609] ***終止應用程序由於未捕獲的異常 'NSUnknownKeyException'，原因：「[setValue方法：forUndefinedKey：]：這個類不是關鍵的編碼密鑰值。「

發生了什麼事情是「one」最初創建（ctrl鍵拖放）的出口，但變量名已在代碼中更改。

作爲一個例子，我已經創建了一個出口名稱爲「一個」以及：

@IBOutlet weak var one: UIButton! // Initially working

然後改名爲一個到改變

@IBOutlet weak var changed: UIButton! // <- Now broken outlet

現在我得到的同樣的錯誤信息：

2016-01-17 18:56：14.059 InvalidOutlet [10158：5713712] ***終止應用程序由於未捕獲異常'NSUnknownKeyException'，原因： '[ setValue：forUndefinedKey：]：此類不是鍵值編碼符合關鍵之一'。

要解決該問題，請通過

打開定義出口故事板擺脫無效的出口參考。
選擇定義出口的組件。
打開「顯示連接督察」（圓圈與箭頭右上方）
刪除無效的口，因爲展現在屏幕捕獲
