Hi, well the question is the one I put in the title: "Should I define overloaded inherited method in the header file in ObjC?"

For example for method ...
I've taken the existing code from this project, and very happy with it so far.

I'm not sure where to start now, but what I need to do is add ...

I have a piece of software that just entered beta. A Japanese version of Mac OS X runs it fine, but a German beta tester gets a message that loosely translates to "Cannot run program because it is not supported on this type of Mac computer."
