I'm following the NSPersistentDocument Core Data tutorial, but
changing things for my little app along the way. For example, instead
of Employees and Departments, I have TrackPoints and Tracks (GPS
tracks).
After following a portion of the tutorial, I got a nice little master/
detail view, with a table of tracks I can add to, and edit, etc. The
tutorial suggested looking at the various connections in IB to get an
idea of how it wired together. I used the Core Data Entity doohickie
in IB to build the master-detail view for me.
Question 1: Is there any way to see, at a glance, all the
interconnections in a .xib file at once?
The next thing I did was add another master/detail view (in the same
window) for the Track entity. What I'd like it to do is, when a track
is selected in the track list, show the points belonging to that track
in the Track Point list.
Question 2: I can see how a text field gets populated when you select
an item in the table. How can I get a one table to populate based on
the selection in another?
TIA,

Rick
