Incorrect. You don't get accessors for instance variables
automatically like that.
To the original poster, there are three approaches you can go with here.
One is to set the variables as @public in the ApplicationDelegate,
then access them as applicationDelegate->theArray. This breaks
encapsulation, but it works.
Another approach is to write accessor methods on the
ApplicationDelegate to return the arrays and use those. This requires
some extra code.
Finally, if you're targeting Leopard, you can use properties. These
can be put together without any extra code, and they don't break OO
like @public variables do.
