How it's implemented now is that I have a separate controller for
each field and the NSTextField delegates to that controller because
for each character, I need to:
- dup-check and possibly count
- change a label to show the count and any dup alerts
- watch for control:completions:forPartialWordRange and provide a
custom list
This seems like boneheaded code duplication, when what I really
want is a more general class that can be told:
Hey! This NSTextField needs to be watched for dups, so split on
[\s*,\s*] and each time a new word shows up, call my method:
theresANewWord:count withDuplicates:dups.
That suggests to me that subclassing NSTextField and allowing a
single controller to register a callback would be the right way to
go, but I'm struggling with how to specify *which* text field and
whether my design idea is even sound.
Sounds to me like you need a small class hierarchy of delegate
classes. Don't make each text-field point to a single controller.
Assign each textfield a delegate object (instance of a specific
delegate subclass) appropriate to the handling that field needs. The
delegate objects may be coupled to the overarching controller for the
"theresANewWord" functionality or the label-changing feature.
