你可以做这样的事情。

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {

     var rootView: MyRootViewController = MyRootViewController()

     if let window = self.window{
            window.rootViewController = rootView
     }

     return true
}
