Question

I have a simple Core Data iPhone app where Parents have a one-to-many relationship with Children. In the first view, you are presented with a list of Parents; tapping on one provides the corresponding list of Children. In the Child view, I want the each cell to show the Child name, and then the Parent name as a subtitle. I have used the following command:

cell.detailTextLabel.text = [[managedObject valueForKey:@"Parent"] description];

But instead of getting the parent name, the subtitle displays something like:

<Parent: 0x4d5a520> (entity: Parent; id...

Obviously I’m printing out the actual relationship, rather than the object’s name. How can I show the actual Parent name (“Mr Smith”)?

Thanks.

Answer 1

I managed to work it out! I’m gradually getting the hang of this programming thing… 🙂

I’ll leave the answer here in case someone else searches for it one day…

Instead of using a generic NSManagedObjectContext with KVC, I used my own subclass:

Child *child = [self.fetchedResultsController objectAtIndexPath:indexPath];
cell.textLabel.text = [child.name description];
cell.detailTextLabel.text = [child.parent.name description];
