Thanks for the clarification. But if there is no GUI or nib
associated with the central controller, how do you load it? Where do
you "plug in"? Are there tutorials on this?
A controller is just an object that plays a specific
role in the MVC design pattern. If you don't want an
object hooked up to any GUI objects or don't want to
use a nib to instantiate it, that's your call. It's
just an object.
Secondly, as it turns out the data I am processing
is very large. I
read that in Objective-C you typically pass actual
objects rather
than pointers to objects. Is that going to be
feasible if I stick it
in a dictionary, or will things bog down?
Thanks for the clarification about the pointers.
That's precisely backwards, at least as far as Cocoa
is concerned. In Objective-C, all objects live in the
heap and they are only dealt with as pointers. If you
try to create an object on the stack, you'll get an
error in compilation.
