[Solved] Difference between Object and Category? [closed]

Really short explanation. I can point you in a direction at least.

Inherit functions of a class. You want to have the same behaviour as the class you just subclassed but with some of your own custom functionality.

Add extra functionality to a class that fits your needs. In other words you could add a method to a class (NSString for example) that lets you count the characters. This can later be called on your NSString class.

You can delegate tasks to another class that has set itself as a delegate. You can force classes to implement certain methods.
