Add NavigationController programatically

[blueFLoyd8]

What is the correct way to add a navigation controller to a view controller (via the code not IB)?

Here is what I've tried. The new sub view is not being added, but the NSLog statement is being printed (in the second group of code):

- (void)loadView {
	[super loadView];
	//Initialize the navigation controller with the info view controller
	if(navController == nil)
		navController = [[UINavigationController alloc] initWithRootViewController:self];
	
	//Present the navigation controller.
	[self.navigationController presentModalViewController:navController animated:YES];

}

Then later in the code:

NSLog("Adding info view");
InfoView *infoViewController = [[InfoView alloc] init];
	//[self.view addSubview:infoViewController.view];
	[self.navigationController pushViewController:infoViewController animated:YES];
	[infoViewController release];

ps. Thanks to everyone who helped me today. I am ready to submit my app after this one little bug is removed. Ive been using addSubView instead of pushViewController and I just need to make this one last change.

The view that is calling this is one of the tab bar controller's views. Is this the reason for the problem?

From UINavigationController Class Referene:
- (id)initWithRootViewControllerUIViewController *)rootViewController
Parameters
rootViewController
The view controller that resides at the bottom of the navigation stack. This object cannot be an instance of the UITabBarController class.

You don't add a navigation controller to a view controller; it's the other way around.

Here's an example from my program:

ManageViewController *manageViewController = [[[ManageViewController alloc] init] autorelease];
UINavigationController *manageNavController = [[[UINavigationController alloc] initWithRootViewController:manageViewController] autorelease];
	
// Couple other controllers set up the same way...
	
[[self tabBarController] setViewControllers: [NSArray arrayWithObjects: tripNavController, prepareNavController, manageNavController, nil]];

I see! I used IB to set up the tab-bar controller, so I guess I cannot do it using code alone. What should I change in IB to make this same change?

In IB I have my Tab bar controller. I changed the first tab's controller class from my own view controller class to UINavigationController.

Then, in the App delegate I added this code. The view never gets shown, only a white view with a top bar (blue)

firstTabVC = [tabBarController.viewControllers objectAtIndex:0];
MyFirstViewController *FirstVC = [[MyFirstViewController alloc] init];
[firstTabVC.navigationController pushViewController:FirstVC animated:FALSE];
	
   // Add the tab bar controller's current view as a subview of the window
[window addSubview:tabBarController.view];
[window makeKeyAndVisible];

For the IB route, just drag a navigation controller directly into your tab bar. Then find the view controller inside of that and set that to be your custom view controller class.

Then you shouldn't need any code.

Yes! Thanks for the help
