I'm filtering an array of dictionaries, my usual procedure for doing
this is:
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"MyKey
CONTAINS[cd] %@", searchString];
NSArray *filteredArray = [[self dataArray]
filteredArrayUsingPredicate:predicate];

First, arrays don't have keys. I'm assuming you mean you need to
filter the items based on values for keypaths off those objects.
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!)

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.
