How do I change the Labels on all three buttons on a UINavigationBar

Question

So, I have the below UINavigationBar :

[ (<- Back)        Info        (Cancel) ]

Now, what I need to do is change the Titles for all the Buttons / Title to One, Two and Three. I tried doing :

self.navigationController.navigationBar.topItem.title = @"One";

But this only updated the button on the left. How do I change all three?

Answer 1

self.navigationItem.title will change the center title, and setting a button with title to self.navigationItem.rightBarButtonItem will change the right button title.

And here's how I've changed the back button title. Note: this code must be used on the previous view controller (the one you'd be hitting the back button to return to), not the presently viewed controller:

- (void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];
    self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Back" style:UIBarButtonItemStylePlain target:nil action:nil];
}
