Most likely, you should import the category header file; although there
are plenty of examples where you don't have to. It is also considered
"good form" (by some) to import it if you use a method from the category.
... and lastly, for example, if you have something like a
#define
statement in the category header file then you must include it if you
want to use the precompiler symbol defined.
