UINavigationController and presenting a modal controller

If got a rootViewController which display's a UIScrollView full screen. When I tap the UIScrollview, I want to flip the screen and display a settings screen (which also has a second screen, the reason for the navigationController).

I am able to display the settings screen by using the following code in my rootViewController: self.navController = [[UINavigationController alloc] initWithRootViewController:self.settingsViewController];

and than: [self.navController pushViewController:self.settingsViewController animated:YES];

My question is: When I'm done in my settings view, how do I return back to the rootViewController, so the controller class in which I have created the navigation Controller and is therefore not on the stack.

I've adopted Apple's solution which they use in the Metronome example.

I'm setting the settingsViewController as the rootViewController for a navigationController. Than I display the navigationController using:

[self presentModalViewController:navController animated:YES];

As per apple's example, I've created a settingsViewControllerDelegate interface which the rootViewController adopts. The interface is not complicated, just a delegate instance var and a callback method (settingsViewControllerDidFinish) which needs to be implemented by rootViewController. In that methode you call:

[self dismissModalViewControllerAnimated:YES];

This way I'm able to have a couple of settings-screens using a navigationController and I'm able to return out of the navigationController back to the rootViewController.
