Just got the book this week and I’m really enjoying it. In the examples, when a new entity is added using a button, the focus is put into the table and the first field in that table. How can I tell IB to drop the cursor into a field instead? For instance, when adding a new recipe, I’d prefer to have the cursor in the name field instead of the name column of the recipes table.

I can see in the attributes tab for the array controller a checkbox for “Select Inserted Objects”, but I don’t see any finer-grained control for this. Is subclassing the array controller and over-riding the add method the way to go here?

Thanks for any help!

I think what I really want is a custom add screen instead of trying to re-point the cursor. The NSPersistentDocument Core Data tutorial seems to cover this variation of adding an entity pretty well.

That is not something you can do in interface builder. To handle that you will need to bind the add button to a method somewhere (probably in the app delegate) and have the add method create the new NSManagedObject and also have it control where the focus moves to.

Needless to say that is not a function of Core Data. It is a function of the controller for the interface.

Thanks Marcus, that makes perfect sense.
