-[NSObject forwardingTargetForSelector:]?

  • Thread-topic: -[NSObject forwardingTargetForSelector:]?

The Leopard Foundation release notes explain how to use the new
-forwardingTargetForSelector: method to get much faster forward invocation
in appropriate circumstances, and it works nicely for me.

But the release notes also say that my non-root class that implements this
method should call super's implementation if my class decides not to return
a value. When I do this in my subclass of NSWindowController, I get a
warning, for example, that NSWindowController may not implement this method.

Sure enough, looking at the NSObject header in the Mac OS X 10.5.1 Leopard
frameworks, I see that this method has been commented out with leading
double-slashes.

Is this an error? Why would it be declared but commented out without
explanation in the release version of the Cocoa Foundation framework?

And what should I do to avoid the warning? If I return nil, everything seems
to work. But I wonder if it will cause problems.
