(2) is fine, especially if you can break off a some compartmentalized
functionality; you can see an example of this the TextEdit source which is
on your hard drive (DocumentReadWrite.m is simply a category on Document).
You might even want to consider:
3. Break the functionality into multiple classes. A long source file is a
"bad smell"; consider refactoring. This makes sense especially if you can
extract some code that is potentially resusable separately. Again, look at
how in TextEdit the EncodingManager is a separate (singleton) object. It is
not quite true that only Document uses it, but it is nearly true. Anyhow my
point is that a helper object that acts as the helper of only one object is
nothing to be ashamed of.
