Core Data unsupported predicate with ALL and IN

Question

I have a request like this :

NSPredicate *predicate = [NSPredicate predicateWithFormat:@\"ANY attributes.attribute.attributeId IN %@\", attributeIds];


        

Answer 1

Fetch all Objects that have at least all attributes in list

NSPredicate *objectsThatContainsAtLeastAllAttributesInList =
    [NSPredicate predicateWithFormat:
        @"SUBQUERY(attributes, $s, $s.attribute.attributeId IN %@).@count == %d", attributeIds, [attributeIds count]];    

Fetch all Objects that have only the attributes in list

NSPredicate *objectsWhoseAttributesAreInList =
    [NSPredicate predicateWithFormat:
        @"attributes.@count == %d AND SUBQUERY(attributes, $s, $s.attributes.id IN %@).@count == %d", [attributeIds count], attributeIds, [attributeIds count]];
