Maybe I misunderstand something about categories, or is the way it is
supposed to work?
That's how it is supposed to work.
Looking at your implementation for removeWhiteSpace, nowhere do you
actually change the receiver (i.e. myString, or 'self' if referenced
inside removeWhiteSpace). And even if you had, it would be an error;
NSStrings are non-mutable. That is, once created they don't change.
Thanks everyone for responding - I now understand what I did wrong.
