I have been inserting objects into the managed object context in code like this.
[[NSManagedObject alloc] initWithEntity:entity
insertIntoManagedObjectContext:moc];
Sometime later the array controller's arrangedObjects property will be
automatically updated.
I have not been using NSArrayController's add: or insert: methods because at
one time I was using them, in addition to
initWithEntity:insertIntoManagedObjectContext:, and I was getting duplicate
objects. Although I tried using both of them together just now (first
initWithEntity:insertIntoManagedObjectContext: and then add:) and I am not
getting any duplicates. So I am a little confused.
Is it normal practice to create a managed object with the designated
initializer initWithEntity:insertIntoManagedObjectContext: and also insert the
object into the controller using the controller's add: or insert: method?
