JBTabBarController

+

JBTabBarController aims to be a drop-in replacement of UITabBarController, but with the intention of letting developers easily customise its appearance. JBTabBar uses images for all UI elements except for the labels on TabBar items. This gives the Developer/Designer the freedom to customise all aspects of the TabBar.

In particular, the images for selected and unselected states can be specified and are colour images not clipping masks. UITabBarItem+JBAdditions.h adds an additional property (selectedImage) to UITabBarItem which specifies the image to show in the selected state. 30 pixel squared images (60 pixels for Retina displays) are recommended for this purpose.

Installation Notes

To use, import all the files in the JBTabBarController folder into your project and include "JBTabBarController.h" where ever it is needed or in your precompiled header.

Also, include "JBTabBarController+ConvenienceMethods.h" if you want to use the convenience property added to UIViewController. This property works the same as the tabBarController property on UIViewController and gives you access to the relevant JBTabBarController from any of the UIViewControllers contained in it. Using this property currently requires JRSwizzle.

The project uses ARC and targets iOS 4.0+ devices.

Todo

Make JBTabBar titles more configurable (font, colour, shadow)
Make JBTabBar more dynamic (swizzle UIViewController title property)
More example TabBars (i.e replicate Apple Trailers and Twitter app tabbars)
Adopt more UITabBarController conventions and behaviours
Make the example compile without JRSwizzle
Automatic resize of tabBar with new backgroundImage (KVO)
Option to hide labels

Example Resources

The included example attempts to emulate the standard UITabBar design provided by Apple. The layer styles used to create the TabBar images in Photoshop are in the Extras folder.

The example JBTabBar uses the following icons from the following authors (all from The Noun Project)
