Objective-c get object that was called selector

Is it possible to get id pointer to object which was called selector inside function with no sender argument?

- (void)didSomeThing {//delegate method may call from any object
//how to get sender = someObj?
id sender = ??
[someObj didSomeThing];

Answer Source

You can't find out who is sender.

Every time you send message to object compiler transform it to:

objc_msgSend(receiver, selector, arg1, arg2, ...)

As you can see here is no way you can find out who is calling method except passing sender as parameter.

You can read more about it here in documentation
