Question

I’m just wondering if its at all possible to add a UIButton or and icon to a UINavigationControllers title bar?

I’m asking because I’m seeking a consistent position to display an “about” button.

You can do that via the viewDidLoad method of the view controller:

- (void)viewDidLoad {
    [super viewDidLoad];

    UIBarButtonItem* infoButton = [[UIBarButtonItem alloc] initWithTitle:@"Info" 
                                                                   style:UIBarButtonItemStylePlain 
                                                                  target:self 
                                                                  action:@selector(infoButtonSelected:)];
    self.navigationItem.rightBarButtonItem = infoButton;
    [infoButton release];
}

In the example about when the button is tapped, you should also have the method:

- (void)infoButtonSelected:(id)sender {
        NSLog(@"button tapped");
        // whatever needs to happen when button is tapped
}
