A set of rootViewController storyboards from NavController to tableView, but when the application starts, displays a different view

Question

I have a basic navigation stack: NavController-> UITableViewController (like rootViewController in NavController) → menu items, the main option of which is a custom viewController. I want my application to start with the main custom view controller as the current view in the navigationController stack, and the back button to the Main menu. Is there a way to use the storyboard to set the stack this way, but when I start it shows a custom view first?

I try to do this in the storyboard as much as possible. I know that I can go to appDelegate and to appDidFinishLaunching ... click customController viewController in navController, but that just seems bad, because then in my appDelegate application I have to reference navController and customController.

Unfortunately, the UIStoryboard not able to visually manipulate the UINavigationController hierarchy. In your case, you need to establish a hierarchy programmatically in the application deletion. Fortunately, because you are storyboards, your application delegate already contains a link to this navigation controller.

In the storyboard, the so-called "initial view controller" will be connected to the rootViewController property in the UIWindow application instance by the time the -applicationDidFinishLaunchingWithOptions: message is -applicationDidFinishLaunchingWithOptions: .

 - (BOOL)application:(UIApplication *)app didFinishLaunchingWithOptions:(NSDictionary *)options { UINavigationController *navController = (UINavigationController *)self.window.rootViewController; MenuViewController *menu = [navController.storyboard instantiateViewControllerWithIdentifier:@"MenuController"]; CustomViewController *custom = [navController.storyboard instantiateViewControllerWithIdentifier:@"CustomController"]; // First item in array is bottom of stack, last item is top. navController.viewControllers = [NSArray arrayWithObjects:menu, custom, nil]; [self.window makeKeyAndVisible]; return YES; } 

I understand that this is not ideal, but if you want to stay in the country of the storyboard, I am afraid that this is the only way.

Although this is not a solution to the storyboard as such, the instance method of the UINavigationController popToViewController: animated: allows you to launch your application using a specific view controller, as displayed.

I use this a lot when testing my applications, so I don’t have to go through the whole stack to get to the VC I'm working on!

I'm not sure what you want to do, this can be done on the Storyboard.
