iOS rightBarButtonItem on UINavigationController in swift

Question

I'm trying to put a rightBarButtonItem on a second view controller of an UINavigationViewController stack.

I'm creating and setting the button in viewDidLoad of the view controller that I want to show. My actual code looks like this:

override func viewDidLoad() {     super.viewDidLoad()     menu_button_ = UIBarButtonItem(image: UIImage(named: "menu"),         style: UIBarButtonItemStyle.Plain ,         target: self, action: "OnMenuClicked:")      self.navigationController!.navigationItem.rightBarButtonItem = menu_button_ } 

What am I missing? The button doesn't appear.

Answer 1

You should set the menu_button_ as the rightBarButtonItem of your viewController rather than the navigationController.

Try

self.navigationItem.rightBarButtonItem = menu_button_ 

instead of

self.navigationController!.navigationItem.rightBarButtonItem = menu_button_
