Core Data - how to generate CoreDataGeneratedAccessors?

Question

I've gone through apple dev website, google and stack overflow to figure out the basics behind CoreDataGeneratedAccessors.

I'm using Xcode 4.2 and core data. I created entities and their relationships properly including inverse.

Following code is failing:

    self.remdetail = [NSEntityDescription insertNewObjectForEntityForName:@"RemDetail" inManagedObjectContext:context];
    [rem addRemDetailObject:remdetail];  --> I'm trying to add rem detail to rem object

because there are no accessor methods generated automatically, I put the following code manually in one of the NSManagedObject subclass. The following code was not generated when i created NSManagedObjects for my entities. I tried to generate accessors automatically by going through few articles and suggestions like Xcode copy & paste etc but nothing is generating the following code.

in rem ManagedObject -->

@interface Rem (CoreDataGeneratedAccessors)
- (void)addRemDetailObject:(RemDetail *)value;
- (void)removeRemDetailObject:(RemDetail *)value;
- (void)addRemDetail:(RemDetail *)value;
- (void)removeRemDetail:(RemDetail *)value;
@end

does anyone know how to generate CoreDataGeneratedAccessors?

Thanks, Rama

Answer 1

Have you checked the switch "To-Many Relationship" in the relationship properties?

Answer 2

@Julien's answer was part of the solution, but here is how I solved it:

1. Make sure that you have a to-many relationship.
2. If you already made a class for your entity, delete it, then with your xcdatamodel open, go to Editor -> create NSManagedObject subclass, and follow the wizard.

The class that is generated will have CoreDataGeneratedAccessors that you are looking for.
