if you don't want to see the back button, use below

self.navigationItem.backBarButtonItem = nil ;

if you want to see your text instead of "Back" button. you could also define your action:.

 self.navigationItem.backBarButtonItem =
      [[[UIBarButtonItem alloc] initWithTitle:@"MyOwnBackTitle"
               style: UIBarButtonItemStyleBordered
               target:self
               action:@selector(backClicked:] autorelease];

Use below code to change the bar text,

UINavigationBar *bar = self.navigationController.navigationBar ;
bar.topItem.title = @"MY Title";

Use this in the viewDidLoad method

[self.navigationItem setHidesBackButton:YES animated:YES];

---

self.navigationController.navigationBar.topItem.title=@"Your Title";
