How to add navigation controller programmatically?

Question

In my app there is requirement that..I have 6 buttons in a nib, when I press any button a new nib will be loaded into the window according to the button pressed. problem is after loading the new nib If I want to come back to the previous nib (which is having all the buttons) how to add navigation controller?

what I am doing now is while loading the new nib when I pressed the button

objNewViewController = [[NewViewController alloc] initWithNibName:@"NewViewController" bundle:nil];
[self.navigationController pushViewController:objNewViewController animated:YES];

but by this way im not able to load the nib, it's not performing any operation?

UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:[[NewViewController alloc] initWithNibName:@"NewViewController" bundle:nil]];

[self presentModalViewController:navigationController               animated:YES];
            [navigationController release];

And in NewViewController: USe this to dismiss and get back to previous view.

[[self navigationController] dismissModalViewControllerAnimated:YES];

you can add leftBarButton to navigation item. Add cancel button and in its action method, dismiss the model.

presentModalViewController is deprecated from iOS 6.0. What can be the alternative of this.

There is a template in Xcode for a navigation based app. It does everything you describe. Well, very close at least, only the AnotherViewController in -tableView:didSelectRowAtIndexPath: is commented out.

In that case, create the UINavigationController using its designated initializer (-init...) and add its view when you need it. You can the push other viewcontrollers on its stack after you've created them with -initWithNib...
