Question

I am trying to have a simple Navigation in my iOS-Project but nothing worked. I am trying since hours and I just don’t get it why it so difficult (I have Windows 8, Windows Phone 8 and Android Apps in the Store).

I have a View which is connected to my Class MainMenu. In the header, I refere to the header of mainmenu.h. And i create a object MainMenuView which is based on the Class MainMenu. In the m-File, I initialize the MainMenuView:

MainMenuView = [[MainMenu alloc] init];

Just for test purpose, I set a Title and this is the only thing which works:

[MainMenuView.navigationItem setTitle:@"Main View"];

I tried a lot of different lines but no lines does the job (simply show the MainMenuView…)

[window addSubview:[navController view]];
UINavigationController *newnav = [[UINavigationController alloc] initWithRootViewController:MainMenuView];
[self setNavController:newnav];
[window addSubview:[navController view]];
[self.navController pushViewController: MainMenuView animated:YES];
self.window.rootViewController = self.navController;
[self.window makeKeyAndVisible];

I added this to the first line, because I read it in some tutorial, but did not help:

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

So, simply I just wwant to display my MainMenu using UINavigationController. Later on, I want to use UINavigationController to navigate to specific Views by pressing specific buttons…

This line would actually crash my app:

[self.navController pushViewController: MainMenuView animated:YES];

Answer 1

I had to use instantiateviewcontrollerwithidentifier, nothing else worked… But this is not written in any documentation or something else, I found it after hours of googling… 🙁
