When the user changes the preference, the view should update its value

So how can I manually make the view update? It seems so simple but I
can't figure out how to do this.
Why not use -setKeys:triggerChangeNotificationsForDependentKey:? Make
the key for your data dependent on the key for the preference, so
that anyone who's watching the data will get a notification when the
preference changes. This way, you don't worry about manually updating
the view -- it'll happen automatically.
