AppDelegate Touch3D Xcode - TabBar

Question

我想在swift 2中第一次在xcode 7.3.1中實現3D Touch。我在info.plist中插入信息，直到這裏工作，你可以從代碼中看到打開視圖的作品，問題是我沒有查看TabBar ...所以我決定改變一切，打開tab控制器，然後從那裏移動selectindex = 2的部分類型，但不知道該怎麼辦...選擇索引函數AppDelegate與工作，有人可以幫助我？

這是我的AppDelegate代碼來管理3D觸摸

func application(application: UIApplication, performActionForShortcutItem shortcutItem: UIApplicationShortcutItem, completionHandler: Bool -> Void) { 
     //questo codice verrà eseguito ogni volta che le Quick Actions verranno eseguite 
     if (shortcutItem.type == "com.tuu.openSearch") { 
      //section search THIS WORK without TabBar!! 
      let viewcontroller = UIStoryboard.init(name: "Main", bundle: nil).instantiateViewControllerWithIdentifier("searchID") 
      dispatch_async(dispatch_get_main_queue(), { 
       self.window!.rootViewController?.presentViewController(viewcontroller, animated: false, completion: nil) 
      }) 

     } 
     if (shortcutItem.type == "com.tuu.openFavorite"){ 
      //section tabbar favorite, self.tabBarcontroller.selectedIndex = 2 not work!! 
      let viewcontroller = UIStoryboard.init(name: "Main", bundle: nil).instantiateViewControllerWithIdentifier("favoritesID") 
      viewcontroller.tabBarController?.selectedIndex = 2 
      dispatch_async(dispatch_get_main_queue(), { 
       self.window!.rootViewController?.presentViewController(viewcontroller, animated: false, completion: nil) 

      }) 
     } 
    }

if (shortcutItem.type == "com.tuu.openFavorite"){ 
      let tabBarController = UIStoryboard.init(name: "Main", bundle: nil).instantiateViewControllerWithIdentifier("favoritesID") as! UITabBarController 
      tabBarController.selectedIndex = 2 
      self.window?.rootViewController = tabBarController 

     }
