How to add right button in the navigation bar?

Question

I have a question to add a right button in navigation bar..

I have two views: View A and View B

I add a navigation bar to view A, after I used self.navigat

Answer 1

Swift code to add a navigation bar button item:

Method 1 (When you wanna use bar button system item)

navigationItem.leftBarButtonItem = UIBarButtonItem(barButtonSystemItem: .add, target: self, action: #selector(addTapped))

Method 2 (When you wanna give your own title to button)

navigationItem.rightBarButtonItem = UIBarButtonItem(title: "Add", style: .plain, target: self, action: #selector(addTapped))

From iOS 5 onwards, it allows you to add more than 1 button on either side of a navigation bar. Something like this:

let add = UIBarButtonItem(barButtonSystemItem: .add, target: self, action: #selector(addTapped))
let display = UIBarButtonItem(title: "Display", style: .plain, target: self, action: #selector(playTapped))

navigationItem.rightBarButtonItems = [add, display]
