In this example you are able to use drag and drop to change the order
of items in a single tableview, and to change group membership of
nested items in objects with relationships, all with Core Data. The
behavior is like iTunes style Playlist / Song relationships.
A few other bonuses:
-an "instant edit" for the groups table that places the users cursor
in editing mode inside the newly inserted row when the user clicks
add.
-delete key removes rows. (care of rentzsch.com)
This code was put together from the Apple DND examples as well as many
of the examples out there on the web.
I have only tested it on 10.5, but I did set the project to build for
10.4, so in theory it should work.
This code is free to use with no guarantees of any kind.
Comments welcome.
