# Creating a UIBarButtonItem

let barButtonItem = UIBarButtonItem(title: "Greetings!", style: .Plain, target: self, action: #selector(barButtonTapped))
self.navigationItem.rightBarButtonItem = barButtonItem

UIBarButtonItem *barButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Greetings!" style:UIBarButtonItemStylePlain target:self action:@selector(barButtonTaped)];
self.navigationItem.rightBarButtonItem = barButtonItem;

# Creating a UIBarButtonItem in the Interface Builder

The example below shows how to add a navigation bar button (called a UIBarButtonItem) in the Interface Builder.

# Add a Navigation Controller to your Storyboard

Select your View Controller and then in the Xcode menu choose Editor > Embed In > Navigation Controller.

Alternatively, you could add a UINavigationBar from the Object Library.

# Add a Bar Button Item

Drag a UIBarButtonItem from the Object Library to the top navigation bar.

It should look like this:

# Set the Attributes

You could double-click "Item" to change the text to something like "Refresh", but there is an actual icon for Refresh that you can use. Just select the Attributes Inspector for the UIBarButtonItem and for System Item choose Refresh.

That will give you the default Refresh icon.

# Add an IB Action

Control drag from the UIBarButtonItem to the View Controller to add an @IBAction.

class ViewController: UIViewController {

    @IBAction func refreshBarButtonItemTap(sender: UIBarButtonItem) {
        print("How refreshing!")

That's it.

# Notes

# Bar Button Item Original Image with no Tint Color

Provided that barButtonItem has a non-null image property (e.g. set in the Interface Builder).


  barButtonItem.image = [barButtonItem.image imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

# Parameters

Parameter Description
title The UIBarButtonItem title
style The style of the UIBarButtonItem
target The object to receive the UIBarButtonItem action
action The selector (method) to be performed when the UIBarButtonItem is pressed

# Remarks

Referencing self.navigationItem assumes that the UIViewController is embedded inside a UINavigationController.
