Question

According to Wikipedia:

Class methods are methods that are called on a class (compare this to
class instance methods, or object methods).

Could you guys please clarify object methods to me?
And Class instance methods are Instance methods if i’m correct?

Answer 1

Trying to rephrase the above Wikipedia quote more clearly in the context of Objective C:

Class methods are methods belonging to the class, rather than to an instance of a class.

Instance methods are methods of an instance of a class; which is often referred to as an object. Sayng “class instance methods” obviously refers to this, but is confusing.
