About the iOS category

This category is for discussion on iOS development.


Categories and augmentations permit you to broaden the usefulness of existing classes without subclassing (acquire nothing) adding usefulness to a current class, even to one for which you don’t have the source.

A category permit you to include (just) techniques to a class by proclaiming them in an interface record (.h) and characterizing them in an execution document (.m), like in an essential Objective-C class. Unfortunately a classification can’t pronounce extra occasion variable for a class.
