Ha! Serves me right for not double-checking the docs before
answering. In my defense, I haven't needed much beyond a number or
date formatter in my ventures and the few times I have, it's been a
"correct or nothing" situation. As a result I had completely
forgotten about that method. Regardless, insert your local 'no
excuse' idiom here. ;-)
As to a more flexible way to filter strings, I would definitely
use NSScanner's -scanCharactersFromSet:intoString: method to filter a
string for any character set (including newlines, etc.). You can
easily create a reusable "MyStringFilteringFormatter" subclass if you
want, that allows you to set which characters it should filter. This
way, the actual character set you're filtering doesn't matter so you
can reuse this formatter anywhere to filter a variety of things. Of
course it's up to you to supply the character set.
I hope at least *that* is helpful. :-)
