在UISplitViewController中使用UINavigationController的UITabBarController打破状态栏

Question

将UINavigationController添加到UISplitViewController中的UITabBarController时，在运行iOS 11的iPad上，状态栏现在会显示导航栏。

示例代码：

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

    self.window = UIWindow.init(frame: UIScreen.main.bounds)

    let t1 = Test2ViewController.init(nibName: "Test2ViewController", bundle: nil)
    t1.view.backgroundColor = UIColor.green

    let t1nvc = UINavigationController.init(rootViewController: t1)

    let tbc = UITabBarController.init()
    tbc.viewControllers = [t1nvc]

    let t2 = Test2ViewController.init(nibName: "Test2ViewController", bundle: nil)
    t2.view.backgroundColor = UIColor.red

    let splitView = UISplitViewController()
    splitView.viewControllers = [tbc, t2]
    self.window!.rootViewController = splitView;
    self.window!.makeKeyAndVisible()

    return true
}
