Custom setter methods in Core-Data

Question

I need to write a custom setter method for a field (we\'ll call it foo) in my subclass of NSManagedObject. foo is defined in the data

Answer 1

I think there is a slight mistake: use

 [self setPrimitiveValue:inFoo forKey:@"foo"];

instead of

 [self setPrimitiveFoo:inFoo];

this works for me.
