I have a situation in my application where I have 2 different

NSComboBoxes to
my controller class. My problem is that I need to be able to able to
identify
which NSComboBox object is calling the delegate, since I need to be
able to do
different things in the delegate depending on the calling object. I
looked in
all the usual places for answers (stepwise, cocoadev, cocoadevcentral,
apple
dev list, and apple documentation), but I haven't been able to find a
answer
to this seemingly common conundrum. I looked into the methods for the
NSNotification object that is passed in, and it seems to give no clue
to who
the caller of the delegate is.
What about NSNotification's -object method?
Kind regards,
Alastair.
