NSPredicate with non-string keys

Hi,

I was wondering if anyone knows how to use NSPredicate on values with keys that are NSNumbers (or any non-NSString, for that matter). I've poured over the documentation and tried many things, from converting to a string to %K, %d, etc argument substitutions and nothing seems to work.

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.

Thanks in advance,
Ben Einstein
