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