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

I'm not sure how it works for Objective-C, but in C and C++ you tell gcc that a parameter is unused by not naming it. Instead of:

int foo (int parmUsed, bool parmUnused)
{
  return parmUsed+1;
}

write

int foo (int parmUsed, bool)
{
  return parmUsed+1;
}
