更新自定义导航栏trasparent Image autolayout Iphone X?

告诉我怎么做自定义导航栏trasparent Iphone X?这是我想要的照片。这是我做的代码。但当我修复图片时,这些变化并没有发生。透明的导航栏和状态栏变得普通。我所有的数据都被我固定的移位了。 告诉我你还需要添加什么,以便我也有它?

我的代码:ViewController

override func viewDidLoad() {
    super.viewDidLoad()

    UIApplication.shared.statusBarStyle = .default


    // Do any additional setup after loading the view.
}

AppDelegate。敏捷的

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {


        UINavigationBar.appearance().setBackgroundImage(UIImage(), for: .default)
        // Sets shadow (line below the bar) to a blank image
        UINavigationBar.appearance().shadowImage = UIImage()
        // Sets the translucent background color
        UINavigationBar.appearance().backgroundColor = UIColor(red: 0.0, green: 0.0, blue: 0.0, alpha: 0.0)
        // Set translucent. (Default value is already true, so this can be removed if desired.)

        UINavigationBar.appearance().isTranslucent = true

        // Override point for customization after application launch.

        UITabBar.appearance().tintColor = UIColor(red:1.00, green:0.88, blue:0.00, alpha:1.0)
        UITabBar.appearance().barTintColor = UIColor.black

        UIApplication.shared.statusBarStyle = .lightContent        

}
