Is there some other way I can inform the compiler
(and a future maintainer) that the parameter is intentionally not used?


Option A) which I use since it works with compilers from that other, lesser, platform most people write code for:

- (void)emptyMethod:(NSNotification*)notification
{
   (void)notification;
}

Option B) when you can assume the requirement of compilers which do not suck:

- (void)emptyMethod:(NSNotification*)notification
{
#pragma unused (notification)
}

In C/C++ you'd have the third option

void EmptyMethod(
   NSNotification* // notification
)
{
}

but I don't believe there is an anonymous argument feature like that in Objective-C since the type of an argument is not sufficient to establish its signature, unlike C/C++. If I'm wrong, I'm sure somebody more clueful will jump in and correct that.
