What is the difference between class and category?..

Answer / Sheo Kumar Gautam

"In Objective-C, a class is the blueprint for creating objects, while a category extends an existing class by adding new functionality. The main differences are that classes have their own .h and .m files, whereas categories are added to existing class definitions."
