iphone fetchRequest sub entities?

Question

If i fetch data from "parent" and assign it to a fetchresultscontroller, i still have to call

[parent.images allObjects]

in my cellForRowAtIndexPath to get to the child data. Is this a normal thing to do or can i get the real data from child right in my fetchedresultscontroller?

Answer 1

You can call

[fetchRequest setRelationshipKeyPathsForPrefetching:@"children"]

Before executing your fetch request to include values for "children" key as well. By default, all relationships will be faulted.
