To help bind my data model to AppKit tables, I’ve written a custom class that implements KVC collection accessors to define a mutable-array property. That is, it implements methods like -countOfEntries, objectInEntriesAtIndex:, insertObject:inEntriesAtIndex, etc. I can then bind this as the contentArray property of an NSArrayController, and use that controller to drive a table view and master-detail UI.
I’d like to avoid using a separate class, though (so I can make this setup more easily reusable.) Is it feasible to subclass NSArrayController and put the collection access methods in the subclass? Then I’d just have an “EntryArrayController” class I could drop into my nib. From the docs I can’t figure out whether this is an appropriate thing to do.
