ios - 从 UITabBarController 和 UINavigationController 访问 UIViewController

Question

我正在开发一个基于 UITabbar 和 View 层次结构的应用程序，如下所示。

UITabBarController ----> UINavigationController ----> UIViewController

我有将打开特定 UIViewController 的推送通知负载，我可以使用 View Controller Storyboard ID 直接显式打开 UIViewController，但不会显示 tabBar 和 Navbar。我怎样才能转到特定的 View Controller 并显示来自 AppDelegate didReceiveRemoteNotifications 的 TabBar 和 NavController。

谢谢!

你必须实例化你所有的 VC 并将它们全部设置为他的前任的根:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    let mainStoryboard : UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
    let yourVC = mainStoryboard.instantiateViewControllerWithIdentifier("YourVC_Identifier");
    let yourNavController = mainStoryboard.instantiateViewControllerWithIdentifier("YourNAV_Identifier") as! UINavigationController
    let yourTabController = mainStoryboard.instantiateViewControllerWithIdentifier("YourTAB_Identifier") as! UITabBarController

    yourNavController.setViewControllers([yourVC], animated: false)
    yourTabController.setViewControllers([yourNavController], animated: false)


    self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
    self.window?.rootViewController = yourTabController
    self.window?.makeKeyAndVisible()



    return true
}
