This should spark some discussion.

I have an app with four subprojects.  I have a main "Controller Object"
which communicates with the File Owner of all the subprojects.  Menus and
Buttons, etc are connected to the Controller Object which then sends
messages to the File Owner objects of the subprojects to init themselves,
load .nib files, and respond to various other methods when needed.

Ok, fine.

In my Controller Object, I have the method:

-free:sender;
{
	(Code to clean up Controller Object instance vars)
	[mySubprojectOwnerObject1 free];
	[mySubprojectOwnerObject2 free];
	[mySubprojectOwnerObject3 free];
	[mySubprojectOwnerObject4 free];
	return self;
}

and each of my SubprojectOwnerObjects has a method:

-free:sender;
{
	(Code to clean up File Owner Object instance vars)
	return [super free];
}

I do this because my subprojects are created and destroyed many
times during the course of the application and I do not want to
grab more memory than I need.

Well yesterday in gdb I noticed that none of my -free methods
are ever being called.  The program exits normally without ever
calling these methods as far as I can tell.

Do such File Owner and Controller objects not need to be freed?
Am I not connecting something or setting up a delegate correctly?
(The File Owner objects sets the proper View as it's delegate.)
If it is a case of not needing to free such objects, what objects
should be freed and what ones not?

Replies received that are not posted in comp.sys.next.programmer
will be summarized.
