Just another note - the reason that I asked this is that I finally
added a second class to my project. I had never had 2 classes in a
project before because I didn't understand how to have them
communicate. Actually, I still don't - I just try everything until
something works.
I wrote the interface and implementation files, and the app would not
load. Of course, I had not instantiated the class because although I
knew that myInstance = [MyClass new]; would make an instance, I did
not know where to put this code. It seemed recursive to put it in the
implementation of itself.
So I dragged out an NSObject in IB, named it the class name, and
everything worked. I still don't understand why. I presume it was that
dragging it out instantiated it. Or maybe having an -init method
instantiated it. Class browser doesn't show instances, so can't check
there.
The reason I want a name for the instance is so I can use it as the
receiver when I send messages to it from another class's methods.

Nothing. That is, not until you add an IBOutlet in whatever class
you want to connect to that instance. Say "AppController" has an
outlet called "thingController". You can then connect the
AppController's someThingController outlet to the "Some Thing
Controller" instance. Now, anywhere within your AppController class,
you can send messages to the "Some Thing Controller" instance by its
shiny new name:
