How do I compare objects in Objective-C?

Question

How do I compare two objects of a custom class? My idea was to add an additional method to the class in which I can compare the current object with another object of the sam

The standard way is to override - (BOOL)isEqual:(id)anObject and - (NSUInteger)hash.

You should read the documentation for NSObject protocol and this SO question has some interesting answers on how to write your hash method.
