I guess I'm not following your logic.
I want table 1 to have a blue background, so I set its tag to 3.
I want table 2 to also have a blue background, so I set its tag to 3.
I want table 1 to have red text. Switch off tag, 3 == red text.
I want table 2 to have green text. Oops - tag 3 already means blue
background + red text.
(Substitute any 2 actual properties for my background color + text
color - they are meant for illustration purposes only.)
Overloading tags for other properties is not scalable, because you
only have one property (the tag) which you are overloading to mean N
other properties and/or behaviors.
The only scalable solution to this problem is explicity
iVars/properties for each property/behavior you want to control in
your subclass. (Yes, this means configuring things by hand after
unarchiving your nib, or writing an IB plug-in so you can specify them
in IB.)
