Implementation.m

UIBarButtonItem* firstButtonItem = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:@selector(someSelector:)] autorelease];
secondButtonItem.style = UIBarButtonItemStyleBordered; // must be set manually
      
UIBarButtonItem* secondButtonItem = [[[UIBarButtonItem alloc] initWithTitle:@"Title" style:UIBarButtonItemStyleBordered target:self action:@selector(someSelector:)] autorelease];

UIToolbar* toolbar = [[[UIToolbar alloc] initWithFrame:CGRectMake( 0.0, 0.0, 100.0, 44.0 )] autorelease];
      
toolbar.barStyle = -1; // removes background, undocumented, make break one day
toolbar.tintColor = self.navigationController.navigationBar.tintColor;
      
[toolbar setItems:[NSArray arrayWithObjects:firstButtonItem, secondButtonItem, nil] animated:NO];
      
UIBarButtonItem* toolbarButtonItem = [[[UIBarButtonItem alloc] initWithCustomView:toolbar] autorelease];
      
self.navigationItem.leftBarButtonItem = toolbarButtonItem;
