Switch between views with UINavigationBar

I've went back to hello world tutorials trying to do this. I can't seem to figure this out for some reason, and yet it should be so simple.

I want to have a UINavigationBar with a button on the right side. When the user presses this button, it takes them to a second view through the slide-to-the-side animation, and on this new view the navigationbar shows a back button to the previous view.

How can i get this to happen? I can't for the life of me figure it out. Is there a tutorial somewhere which goes over it? I can't find one.

On the button action (the selector) use the following message on self.navigationController

 pushViewController:secondViewController animated:YES

EDIT: Create the UINavigationController as follows:

UINavigationController* navController = [[UINavigationController alloc] initWithRootViewController:rootViewController];

And then set the right button as required suggested by Sorin in his answer. And use pushViewController:animated: message on self.navigationController as I have already posted in my original answer. Hope it helps. rootViewController is the view controller you want to have pushed as the first view on your navigation stack.

You should create an UINavigationController with an UIViewController as a root. in the UIViewController you should setup the bar right button. you should have something similar to this:

self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] 
                        initWithTitle: @"Next"
                        style:UIBarButtonItemStyleDone 
                        target:self 
                        action:@selector(nextPage:)] 
                        autorelease];

when you touch the button the method nextPage: will be called and will execute the push of the new view.

-(void)nextPage:(id)sender
{
   UIViewController *secondViewController = [[UIViewController alloc] init];
   [self.navigationController pushViewController:secondViewController animated:YES];
   [secondViewController release];
}

here is a tutorial in two parts for using an UINavigationController and here is the official documentation for the UINavigationController(really useful).
