NavigationItem in Master/Detail application

Question

I wrote a Master/Detail Application by using the Master/Detail template of XCode. After starting the app, the title of the navigation button for the master view is just "Master". Now I waant tio rename that button, but unfortunately I don't know how to access this button. In appdelegate.m there is the following code to initialize the views:

MasterViewController *masterViewController = [[MasterViewController alloc] init];
UINavigationController *masterNavigationController = [[UINavigationController alloc] initWithRootViewController:masterViewController];

DetailViewController *detailViewController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil];
UINavigationController *detailNavigationController = [[UINavigationController alloc] initWithRootViewController:detailViewController]

I tried these ways without success:

masterViewController.navigationItem.title = @"newTitle";

or

masterNavigationController.navigationItem.title = @"newTitle";

As I wasn't sure, if the name of the button is just the title of the view behind idt, I also tried that:

masterViewController.title = @"newTitle";

Nothing worked. But as the title of the button is "Master" and I definitely didn't set it, I believe there must be some way to set it. Does anyone know how to do it?

Just to show the button:

If you would have created Master/Detail application using Master/Detail Template, then go to your "MasterViewController.m" file and change the string "Master" as you wanted. See the below image it would be like this in your MasterViewController.m.

UPDATE: and also change the barButtonItem name in the DetailViewController.m as like below. This will do the trick.
