IB doesn't init it when it is instantiated? I didn't realize.
That's a difficult area. Of course all the objects *are* init'd, but
the concrete init method used changes (at the first look, at
least :)) in a totally random way :) It tends to be initWithCoder:
often, but not always, depending on the NIB layout details which you
don't want to learn actually (I did, and forgot happily long ago :)).

Cheers guys. I hadn't realised that you could use static outside of
a method. This way I can set the value in my object's init method :)

I have a custom class that I instanciate in my MainMenu

I want to do is be able to issue the command:
[MyClass sharedInstance]

this with a class that is only instanciated once the
sharedInstance message is received, but the object pre-exists.
NSDocumentController is capable of this. Any ideas?

In your implementation file have a static pointer to
your class.
Assign self to it in your awakeFromNib method.
Now you can have a class method that returns the shared instance,
or throws an exception if it's not defined.
