Category is an objective-c feature which allows to add additional methods to a class for which we don't have source code.We can add additional methods to classes like NSString,NSArray etc.
Any methods that you declare in a category will be available to all instances of the original class, as well as any subclasses of the original class. At runtime, there’s no difference between a method added by a category and one that is implemented by the original class.
