//add a right btn to the navigation bar

UIView *customView = [[UIView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 75.0f, 30.0f)];

UIButton *btn1 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[btn1 setFrame:CGRectMake(0.0f, 0.0f, 30.0f, 30.0f)];
[btn1 setTitle:@"1" forState:UIControlStateNormal];
[btn1 addTarget:self action:@selector(btn1Tap:) forControlEvents:UIControlEventTouchUpInside];
[customView addSubview:btn1];

UIButton *btn2 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[btn2 setFrame:CGRectMake(35.0f, 0.0f, 30.0f, 30.0f)];
[btn2 setTitle:@"2" forState:UIControlStateNormal];
[btn2 addTarget:self action:@selector(btn2Tap:) forControlEvents:UIControlEventTouchUpInside];
[customView addSubview:btn2];

UIBarButtonItem *rightBtn = [[UIBarButtonItem alloc] initWithCustomView:customView];
[self.navigationItem setRightBarButtonItem:rightBtn];

Since iOS 5 there are this 4 methods available

- (void)setLeftBarButtonItems:(NSArray *)items animated:(BOOL)animated;
- (void)setRightBarButtonItems:(NSArray *)items animated:(BOOL)animated;
- (void)setLeftBarButtonItems:(NSArray *)items;
- (void)setRightBarButtonItems:(NSArray *)items;

where you can set an array of UIBarButtonItem

example:

NSArray * buttons = @[button1,button2];
[self.navigationItem setRightBarButtonItems:buttons];
