Comrades:
Geez, I am feeling totally wrapped around the axle here.
I have posted questions on this project a couple of times, and have
gotten useful answers that allow me to continue. Sometimes I think I
am heading deeper into the weeds, though. So, let me try rephrasing
my situation and try to ask a more specific question. Maybe the
answer will put me back on track.
The project I am working on is used to make and distribute copies of
certain files. I am trying to add a module that will do some extra
processing of the files, and then distributing copies of that new,
processed file. I was given the interface (a window with a bunch of
popups and stuff) for the new module in the NIB, and there was
originally a category (AppController(ExtraCategory)) for the extra
"module".
Some of the functionality of the original copy code would be handy to
reuse, but there are code dependencies in there that I don't want to
touch, so I am planning to replicate the copy code and modify it for
the new module. Not very OOP-sy, but what the heck, sometimes you
just can't do things the way you would like.
I tried making a new controller for the new window/module, on the
theory that since they don't share much data or functionality, they
ought to be separate class objects. However, I am had some problems
with that approach. In particular, I was getting several runtime
errors of the type: "Could not connect the action
someNSApplicationAction: to target of class MyController". I don't
understand this at all, but I am more worried that I am just
completely off track in trying to create a new controller, and that
fixing this problem will just allow me to go even farther into the
weeds.
So, here is my question:
Given my description of this project, does the two controller
solution sound like the best one? Does anyone have any tips on how to
re-factor this thing? My first effort kind of blew up in my face. I
could not figure out how to do it gradually, so I just did a major
cut/copy/paste/change-some-connections/rename-some-stuff kind of
thing, and then built and ran it, but I don't know enough about the
Cocoa/ObjC/IB/Xcode system to figure out what went wrong.
(And, a followup question would be: where could I find an example of
an app that has multiple controllers which do not relate to the same
document? The samples I have looked at so far seem to be based on the
MCV pattern. I am looking for something more like MCV(1)+MCV(2).)
Paul
