3. 删除文件

4. 在AppDelegate文件加入：

   func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        self.window = UIWindow();
        let mainWindow:UIWindow! = self.window;
        mainWindow.rootViewController = ViewController.init();
        mainWindow.makeKeyAndVisible();
        return true
    }
