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.
