Dear list,
I know that this question is very common, but could
someone please help me? All of the examples I've
found only cover adding default items to a tableview
and then letting the user modify the text... I need
to know how to make insert: and remove: have different
functionality...
A coworker keeps suggesting the use of a delegate, but
I can't see how that would apply...
