I didn't see this in the archives, but it feels like it should be an
obvious question. I have a custom view that displays a collection of
objects. I'd like to do something like NSTableView/NSTableColumn
where I can just say "bind the text to an array controller's
arrangedObjects.text and the label to arrangedObjects.label."
However, I don't see how the custom view will be able to get
information from the array controller (selection, # objects, etc.)
without specifying the array controller as an outlet. I guess you
could have a selection + objects array in the view that you bind the
array controller's selection and arrangedObjects items to, but that
seems more complicated than it should be. Is there a clean way to set
it up like NSTableView?
Hello Josh Anon,
You register for KVO notifications on the array controller inside bind:
and update the view's contents when observeValueForKeyPath: is called.
That method passes in the bound array controller, so you can just query
it directly for its new contents, using the key path specified during
the initial bind.
