ios - 如何从应用程序委托(delegate)导航内部 View Controller

Question

在我的应用程序委托(delegate)中，这就是我导航到 SWRevealViewController

的方式

let revealViewController = mainStoryboard.instantiateViewControllerWithIdentifier("RevealView") as? SWRevealViewController


        self.window!.rootViewController = revealViewController
        self.window?.makeKeyAndVisible()

我从 SWRevealViewController 的 FrontViewcontroller 导航到该内部 View Controller ，如下所示。

let secondViewController = self.storyboard?.instantiateViewControllerWithIdentifier("Read") as! ReadViewController
        secondViewController.title = self.selectedTitle
        self.navigationController?.pushViewController(secondViewController, animated: true)

现在在 AppDelegate 中，当收到推送通知时，我想导航此 ReadViewController。当我单击后退按钮时，它应该返回到 FrontViewController ，就像正常情况一样。如何在 AppDelegate 的通知委托(delegate)中执行此操作请帮我。谢谢

试试这个:

let yourVC = mainStoryboard.instantiateViewControllerWithIdentifier("Read") as! ReadViewController

let frontViewController = mainStoryboard.instantiateViewControllerWithIdentifier("frontViewController") as! FrontViewController

let navController = UINavigationController()
navController.viewControllers  = [yourVC,frontViewController]

self.window!.rootViewController = navController
self.window?.makeKeyAndVisible()
