In talking off-list with another list member, he mentioned that I
needed to bind the Selection Indexes and Sort Descriptors of one of
my NSTableViews to the same for the controller for that table view,
in this case MessagesController. That's fine and I appreciate the
tip. (I'm not entirely sure I understand why, but at least I know I
need to investigate this aspect of bindings more.)
I'm not sure why you would expect a tutorial on Core Data to
explain the use of table views, sort descriptors, and the like. Cocoa
is a huge API with a lot of beginner-to-intermediate-to-advanced
technologies. Examples:
NSTableView & Sort Descriptors: beginner
Cocoa Bindings & Core Data: advanced
Given that distinction, is it any wonder that a tutorial on an
advanced part of the API casually references beginner-level topics
without explaining it? More importantly, if you were already fully
versed on sort descriptors, would it not be frustrating, time-
consuming, and annoying to have to fish through those details in every
article that makes use of them?
If anyone can offer tips about how to overcome this aspect of my
experience I would greatly appreciate it.
If you want advice for overcoming your problem, the only advice
anyone can really give is to widen your scope and read more of the
documentation.
For what it's worth, this is specific to Cocoa. I've run into this
"problem" (interdependent concepts) in every language / API /
complicated technology. It takes research, for which there is no
substitute.
