Don't try to return it but work with 'call by reference' (in stead of
call by value).
Note: use also a class and not a primitive type, for example: NSNumber

I wish it to return a INT and I figure that that qualifies as in-
significant. Given that assumption, my real question is how to
implement it. I call:
[self performSelectorOnMainThread:@selector:mySimpleSelector
withObject:nil waitUntilDone:YES];
(int) mySimpleSelector {
if (whatever) return 0;
else return 1;
}
via my call to -performSelectorOnMainThread, just how do I access -
mySimpleSelector's returned INT? The simplest answer is to not have
a return value at all, but rather store the INTs in a global; but I
figure there is no time like the present to learn to solve this
problem the right way.
