Using NSPredicate to search an array with an array

ios, nspredicate, objective-c

Solution

Considering `array` contains card Object.

 NSArray *keyWordsList = [keywords componentSeparatedByString:@","];
 [array filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"ANY %K IN %@",@"tags",keyWordsList]]

EDIT:

To search partially you can use LIKE operator.

[array filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"ANY %K LIKE[cd] %@",@"tags",[partialkeyWord stringByAppendingString:@"*"]]]

Problem

I have an array of `Card` objects (NSObjects), each with a field called `tags`, which is an NSArray of NSStrings. I would then like to split up the user's search term into an array called `keywords` of strings by `componentsSeparatedByString`, then use NSPredicate to filter my array of Cards based on which elements have tags containing at least 1 keyword in `keywords`. I hope that's not too convoluted! I've tried using the NSPredicate `IN` clause to no avail. How should I do this?
