UINavigationController initiWithNibName not loading the design from the .xib file

Question

In app delegate, inside didFinishLaunchingWithOptions function, I have the following code to load a view that is a UINavigationController:

 UINavigationController *navcon=[[UINavigationController alloc] initWithNibName:@"ThirdView" bundle:[NSBundle mainBundle]];

FirstView *fv=[[FirstView alloc] init];

[navcon pushViewController:fv animated:NO];

[fv release];


[self.window addSubview:navcon.view];


[self.window makeKeyAndVisible];
return YES;

The .xib "ThirdView", that is a UINavigationController View, actually looks like this in the Interface Builder:

But when I run the app, the app looks like this:

Why is the application not loading the Navigation Bar design of "ThirdView.xib" UINavigationController as I have designed it in the Interface Builder?

Update: Here is how "FirstView" looks like in IB:

Answer 1

I don't believe that what you are trying to do is valid. UINavigationController is intended to be a container for other views. You create the UINavigationController and then add your content to it by pushing view controllers onto it with pushViewController:animated:. It is the pushed view controllers that are created with .xib files.

Answer 2

Each UIViewController in a Navigation controller is responsible for providing content to be display on the navigation bar.

In your view didLoad method of your FirstView do the following

self.navigationItem.title = @"your title";

But can you also post how your FirstView look in IB?

Personally I never setup the navigation bar in IB. Here how you can set 2 button in code for your Navigation bar

self.navigationItem.leftBarButtonItem = self.editButtonItem;

UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(insertNewObject)];
self.navigationItem.rightBarButtonItem = addButton;
[addButton release];

This code come from a UITableViewController subclass.
