I think this is a very basic question and I'm just not finding the
answer. I want to get the many data for a given relationship. Lets
say I have a Department and I want to get all its Employees.
Department has a relationship called employees. Is this what I do?
id result = [aDepertment valueForKey:@"employees"];
What do I get back? Is it an array, a set, or some other kind of
container?
Should I be using mutableArrayValueForKey from NSKeyValueCoding
protocal?
I have been reading the Core Data docs and all the examples show
situations that return only one object.
thanks for the help
