So I think my question here, is, what should I use when inserting a
detail object to properly set the relationship to Account.
some example on how I should approach the problem would be nice, or
a step-by-step :D
I do this, where I have an EventImage that refers back to a main
Event, "self" is the managed object for the Event, which is your
Account:
// create new EventImage, this would be akin to your
AccountDetails
imageHolder = (EventImage*)
[NSEntityDescription
insertNewObjectForEntityForName:@"EventImage"
inManagedObjectContext:
[self managedObjectContext]];
[imageHolder setImage:image]; // set some data in the new
object
// Add reference from Event to it's Image
[self setValue:imageHolder forKey:@"imageHolder"];
// Add the reverse relationship, from the image back to the event.
[imageHolder setValue:self forKey:@"event"];
