Obj-C introspection: How can a method reference its own selector?

Question

I wish to write a macro, to be used within any method, which references the method\'s selector. I do not wish to pass the literal name of the method. For example:

Answer 1

Methods get an implicit argument _cmd, which is the selector.

Answer 2

_cmd represents the selector of the current method -- it is a hidden argument (like self).

if you never need arguments, or nil is suitable for your purpose - all you need to do is write:

#define RERUN [self performSelector:_cmd]
