        self.window = UIWindow(frame: CGRect(x: 10, y: 100, width: 200, height: 300));
        self.window?.layer.masksToBounds  = true;
        self.window?.layer.borderColor  = UIColor.brown.cgColor;
        self.window?.layer.borderWidth  = 5;
        //默认加载的视图
        let nav1 = UINavigationController(rootViewController: Page1(nibName: nil, bundle: nil));
        self.window!.rootViewController = nav1
        self.window?.makeKeyAndVisible()
        //self.window 也可以被其他view.addSubview(self.window) 放入到 指定容器中
        
     
        
    }

    {
   
        // 定义一个控制器
        let tow_vc = Page2();
