Sorry, typo, I meant FILTER an array.
So is there any way to filter with numberic keys? I guess I could
convert all they keys to strings? Urgh....
Is there any way to filter using all keys in a dictionary?
Thanks for you help (so far!)

I was wondering if anyone knows how to use NSPredicate on values

the documentation and tried many things, from converting to a
string to %K,
%d, etc argument substitutions and nothing seems to work.
Alphanumerics only, I'm afraid. Keypaths can't contain invalid keys,
and numbers are not valid keys.
If there's no way to do this, I've also tried ALLKEYS, but I can't
get that
to work either. Is this possible? If it matters, I'm just creating
the
predicate with predicateWithFormat: and sorting an array.
Why aren't you using a sort descriptor?
