ALL,
I found this which answer my question perfectly.
However, I need some clarification. AFAIU, [itmeAtIndex: 0] will give the reference to the Apple menu and not to the application menu. I'm talking about the menu which a little Apple sign displayed on the menu bar. Or this Apple menu is not countable in this case and the application menu is located at position 0?
A little OT: it had been MY experience that trying to comment on the old question nobody will ever try to reply. So I made this new thread here hoping that someone will notice it and reply.
Thank you in advance.
