hi, I am working in xcode on an ipod app in objective C, and I have a field (navigationController) in one of my classes (rootViewController). How do I reference the instantiated rootViewController's navigationController from another class? For example, how would I do this if I want to reference the navigationController from the FirstViewController.m class?

I seem to only be able to find references for this to reference the application delegate.

If I want to reference the application delegate with FirstViewController, I just say:

MyAppDelegate *delegate = [[UIApplication sharedApplication] delegate];

[delegate.navigationController pushViewController:childController animated:YES];

how do I do this for the rootViewController class instead of MyAppDelegate?
