I want to add a right bar button item to the navigation bar, so that on click, it performs certain a function.

I have created the following code to add the right bar button item, but after it is done, the bar button item is not getting displayed in navigation bar:

-(void)viewDidload{
    self.navigationItem.rightBarButtonItem = 
    [[[UIBarButtonItem alloc] 
           initWithBarButtonSystemItem:UIBarButtonSystemItemAdd                                                                                                     
                                target:self
                                action:@selector(Add:)] autorelease];    
}

-(IBAction)Add:(id)sender
{
    TAddNewJourney *j=[[TAddNewJourney alloc]init];
    [app.navigationController pushViewController:j animated:YES];
    [j release];
}

    -(void)viewDidLoad
{ 
    [super viewDidLoad];
    app.navigationController.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(Add:)] autorelease];
}

-(IBAction)Add:(id)sender
{
    TAddNewJourney *j=[[TAddNewJourney alloc]init];
    [app.navigationController pushViewController:j animated:YES];
    [j release];
}

    Try the other answers. I posted this answer so that it will work if your viewcontroller does not have a navigation controller which i think is the problem.
