You can change the title of the back button and put a rightBarButton on the screen using the following code.
In the – (void)viewDidLoad method, just after [super viewDidLoad]; put this code.
UIBarButtonItem *backButton =
UIBarButtonItem *backButton =
[[UIBarButtonItem alloc] initWithTitle: @"Main"
style: UIBarButtonItemStyleBordered
target: nil
action: nil];
self.navigationItem.backBarButtonItem = backButton;
UIBarButtonItem *helpButton =
[[UIBarButtonItem alloc] initWithTitle: @"Help"
style: UIBarButtonItemStylePlain
target: self
action: @selector(goToHelp)];
self.navigationItem.rightBarButtonItem = helpButton;
self.navigationItem.rightBarButtonItem.enabled = YES;
If you don’t want a back button use this
[self.navigationItem setHidesBackButton:YES];
