#GONCategories Objective-C categories, used for years in my projects.
Some categories were not written by me, is so I've added the original source in header comment, but I may have missed some.
If so, do not hesitate to tell me, I will update headers to add the original source.

##Usage Simply call method you want to use with appropriate parameters.

##Installation CocoaPods: pod 'GONCategories'
Manual: Copy the Classes folder in your project

Import wanted headers in your project. .pch is a good place ;)
You can also import GON_Categories_All.h to add all categories in your project.

Main headers

GON_Categories_All.h : Import all categories
GON_CoreData_All.h : Import all core data related categories
GON_FoundationExtensions_All.h : Import all foundation related categories
GON_UIKitExtensions_All.h : Import all UIKit related categories
GON_StoreKitExtensions_All.h : Import all StoreKit related categories
