Best practices : use array controller to insert objects into managed object context

  • I have a NSTableView which handles viewing of managed objects, via an
    NSArrayController (which is bound to a managedObjectContext, and to a
    contentSet).  When adding managed objects to the managed object
    context, I want to add them such that I can determine where the newly
    inserted objects will appear within the table view.

    I came across some sample code that showed the following steps:

    1) Create a new managed object via
        newObj = [NSEntity
    insertNewObjectForEntityForName:inManagedObjectContext:]

    2) Insert the new managed object into the array controller
        [arrayController insertObject:newObj atArrangedObjectIndex:i]

    This works fine, in that I get a single object added to the object
    context, and it appears at the correct location in the table view.

    My question is the following: is this a good methodology to use, or
    should I be following a different path?  That is, is it valid to add/
    insert objects to the controller, after having created the object via
    NSEntity?

    Thanks,

    Dale
