使用ApplicationShortCut SIGTRAP時發生崩潰

當我試圖使用ApplicationshortcutItem導航到視圖控制器時，我的應用程序立即崩潰。但是，我的其他應用程序快捷方式（1 viewcontroller更多）不會顯示此行爲。導航到相同的視圖控制器不起作用，不會使其崩潰。使用ApplicationShortCut SIGTRAP時發生崩潰

我崩潰：在Appdelegate

方法來顯示視圖控制器：

if let rootViewController = window?.rootViewController, let shortcutItemType = DGShortcutItemType(shortcutItem: shortcutItem) { 
      rootViewController.dismissViewControllerAnimated(false, completion: nil) 
      switch shortcutItemType { 
      case .Message: 
       let storyboard = UIStoryboard(name: "Main", bundle: nil) 
       let rootTabbarController = self.window?.rootViewController as! UITabBarController 
       let firstNav = storyboard.instantiateViewControllerWithIdentifier("NavController") as! UINavigationController 
       rootTabbarController.viewControllers![0] = firstNav 
       let VC1 = storyboard.instantiateViewControllerWithIdentifier("PeriodeView") 
       let VC2 = storyboard.instantiateViewControllerWithIdentifier("weekViewController") 
       let VC3 = storyboard.instantiateViewControllerWithIdentifier("timesInsertViewController") 
       firstNav.viewControllers.insert(VC1, atIndex: 1) 
       firstNav.viewControllers.insert(VC2, atIndex: 2) 
       firstNav.pushViewController(VC3, animated: false) 
       break 
      case .Time: 
       let storyboard = UIStoryboard(name: "Main", bundle: nil) 
       let rootTabbarController = self.window?.rootViewController as! UITabBarController 
       let firstNav = storyboard.instantiateViewControllerWithIdentifier("NavController") as! UINavigationController 
       rootTabbarController.viewControllers![0] = firstNav 
       let VC1 = storyboard.instantiateViewControllerWithIdentifier("PeriodeView") 
       let VC2 = storyboard.instantiateViewControllerWithIdentifier("weekViewController") 
       firstNav.viewControllers.insert(VC1, atIndex: 1) 
       firstNav.pushViewController(VC2, animated: false) 

       // Display an alert indicating the shortcut selected from the home screen. 
       break 
      } 
     }

注case .Time被調用運行。

該視圖顯示一個tableview並使用全局變量'pressedYYY'，該名稱在導航到viewController之前設置。我的應用程序委託也設置這個非常相同的變量。

我該如何解決這個問題？因爲我不能清楚地看到它出錯的地方
