Well, the accessor method I had in mind, in its entirety, is:

Thanks Graham,
Looks simple enough, however, I can't seem to make it work.
I get a warning "warning: instance variable 'MyOutlet' accessed in a
class method"
If I pause the execution in the implementation where MyOutlet is
defined I see that it has valid pointers to memory:
NSTextField * MyOutlet 0x12c650
Class isa 0xa027f1e0
In the other implementation that I am attempting to get the value of
MyOutlet from, I am calling your suggested MyOutlet accessor method
with:
id MyOutletID = [MyContent MyOutlet];
MyOutletID has a pointer to memory, but the corresponding 'isa' class
does not:
id MyOutlet 0xba4041
Class isa 0x0
And when I step passed the line:
float MyOutletFloat = [MyOutletID floatValue];
I get the message 'Program received signal: "EXC_BAD_ACCESS".'.
So far the only way I have been able to get the value of MyOutlet from
a different class is by using a NSTimer function to set a global with
the value of MyOutlet, then call a function to return the value of the
global. This seems far from ideal, and while it is fine for testing
purposes, I am curious on how to do it the "right" way.
note: by naming things as to their function you'd probably end up
with a much more self-descriptive method.
Indeed, they are, just named them that for clarity here.
