FFBadgedBarButtonItem

FFBadgedBarButtonItem is a UIBarButtonItem subclass that allows you to create a button with a custom image that supports badging for the Navigation Bar.

Overview

Icon badges and tab badges are used commonly to convey information to the user that there is something that needs their attention. A bit surprisingly, there is no support for badging UIBarButtonItem's, however. Enter FFBadgedBarButtonItem.

Utilizing the UIBarButtonItem's customView attribute, FFBadgedBarButtonItem allows you to create a button with a custom image that supports badging.

Usage

Using FFBadgedBarButtonItem is easy:

Add FFBadgedBarButtonItem.{h,m} to your project, and include the .h file where you need it.

Create the button:

UIImage *image = /* ... */
self.navigationItem.leftBarButtonItem = [[FFBadgedBarButtonItem alloc] initWithImage:image target:self action:@selector(doSomething:)];

Update the badge:

FFBadgedBarButtonItem *button = (FFBadgedBarButtonItem *)self.navigationItem.leftBarButtonItem;
button.badge = @"3";
