Help with CoreData making a NSPredicate - Recursive Searching

Question

I am using CoreData for an iPhone project and I am stuck trying to build a predicate.

My core data entity is

Folder 
   parent  - Point to the fol         


        

Answer 1

How about going back up through the relationship:

NSPredicate *pred = [NSPredicate predicateWithFormat:"parent.secure = %@", [NSNumber numberWithInteger:kNoSecurity]];
