CategoryData Description

Allows Objective-C developers to attach arbitrary data to any object at runtime The Objective-C categories system is a powerful tool, allowing you to extend existing classes, even those built into system frameworks, with additional methods. Unfortunately, categories can only add methods to classes, not data. If you wish to extend an existing class with extra instance data then you need to subclass.CategoryData is a free and open source NSObject category that provides Objective-C developers with the ability to add and remove data to any object instance at runtime.CategoryData can be used on its own, but the primary purpose is to allow you to write categories that extend classes with new data.Installation: To install CategoryData into your app, drag the CategoryData.h and .m files into your project. Then simply include the header wherever you want to use the CategoryData methods. Requirements: · Apple Xcode
