Swift不使用storyboard 之 添加navigation

storyboard虽然非常强大，但是作为一个自由的开发者我们不应该被鼠标键盘束缚。最好的设计软件就是我们强大的内心。

添加Navigationcontroller

 func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        
        let navigation = UINavigationController(rootViewController: ViewController())
        window = UIWindow()
        window?.makeKeyAndVisible()
        window?.rootViewController = navigation
        return true
    }

修改title

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
        view.backgroundColor = .yellow
        navigationItem.title = "sport"
    }


}
