Quick question:
Where in the MVC paradigm would the NSValueTransformer fit and why?
I don't think every object has to fit into one of those three slots.
So, I'd say none. They don't hold data, they don't interact with the
view. They could be considerer controllers I suppose if you
absolutely have to put it someplace.
they typically reside between M and V or V and C.
(Is the above a typo... did you mean "M and C or V and C"?)
I emailed the original poster via private mail earlier today (dunno
why) with the opinion that it's part of the controller layer (not to be
confused with The Controller Layer). I don't think it's a controller
itself, but it's a mechanism the controller uses to glue the model and
view together. Namely, it transforms data into a form suitable for
storage in the model and for display in the view.
I also mentioned that you can contrast these with formatters, which are
just parts of the view. This is because they don't actually change the
model's data, just the way it is displayed.
Just throwing out a different opinion.
