Hello...
I would recommend that you write the interface declaration anyway,
since it would be trivial to do.
@interface myclass: rootclass
- (void)yo; /* you wouldn't even need this line if the rootclass
already declared the yo method */
@end
You could just add these two/three lines for each of the two
subclasses in the header file of the main class if you didn't want to
make seperate header files, but it's not a whole lot of work to make
a few extra header files either. If this is for some type of
framework you could make the subclass headers private headers if you
wanted.
The only hidden pitfall I can think of it that you wouldn't be able
to make a subclass of one of those classes without writing the
interface declaration at that point, but there could be others...

Are interface declarations necessary? I have a sort of class
clusters situation where I have the main class and one or two
subclasses that have very slight differences which are actually
returned. Neither of them have extra member variables, so I would
really like to just write the implementation. I tried just skipping
the interface declaration and it seemed to work, all I got was a
warning but it ran fine. Is there an "accepted" way to do this?
Are there any hidden pitfalls in doing this?
basically i did this:
@implementaiton myclass: rootclass
- (void)yo
{
//crazy stuff
}
@end
