Is there a preprocessor macro that expands to the current selector?

Obj-C introspection: How can a method reference it's own selector?

This applies to Objective-C, is there a preprocessor macro or something to get the SEL value of the current selector? Specifically I'm looking for something like:

-(void) someSelector
{
    SEL mySelector = __CURRENT_SELECTOR__;
    NSLog(@"I'm in selector %@",NSStringFromSelector(mySelector));
}

it's kinda like the __FILE__ macro but this to obtain the current selector. Pretty useful to pass it to others while not worrying to update it if the selector name is changed.

Every method has two implicit parameters, self which is an id (the receiver) and a SEL called _cmd, which is probably what you want.

Note that this has nothing to do with preprocessor or anything before compile-time, _cmd is not a macro, it's an argument.

-(void) someSelector
{
    NSLog(@"I'm in selector %@",NSStringFromSelector(_cmd));
}
