Add a button to a navigation toolbar

How can a button be added to a navigation toolbar in an application which is navigation based?

The rootController is a tableView by default, and this is perfect. I would like to add a "share" button to the navigation controller so that I can attach it to my own method.

How is this done if the navigation bar is added in the code somewhere?

To do it in code, go to your views viewDidLoad method and create a UIBarButtonItem

This code will create a button that says share like you wanted and put it on the right hand side of the navigation bar.

- (void)viewDidLoad {
     [super viewDidLoad];
     UIBarButtonItem *shareButton = [[UIBarButtonItem alloc] initWithTitle:@"Share"     style:UIBarButtonItemStyleBordered target:self action:@selector(share)];

    self.navigationItem.rightBarButtonItem = shareButton;
    [shareButton release];
}

You can create an UIBarButtonItem and attach it to a root view controller's navigation item. You add a target-action pair when you initialize the UIBarButtonItem object and that action message will be sent to the target on a user tapping on the button.

So if you want the button when the table view is shown, set the UIBarButtonItem to your table view controller's navigationItem.rightBarButtomItem property.

This makes an add button, but you get the idea.

self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc]
  initWithBarButtonSystemItem:UIBarButtonSystemItemAdd 
  target: 
  self action:@selector(buttonPressed:)] 
  autorelease];

UIBarButtonItem *shareButton = [[[UIBarButtonItem alloc] initWithTitle:@"Share" style:UIBarButtonItemStylePlain target:self action:@selector(yourShareAction)] autorelease];


self.navigationItem.rightBarButtonItem = shareButton;
