Yeah, good point. Maybe overriding "arrangeObjects:" (without the "d") would work better in that case.
I think you'd have to override a lot of functions:
- addObject:
- addObjects:
- insertObject:atArrangedObjectIndex:
- insertObjects:atArrangedObjectIndexes:
- removeObjectAtArrangedObjectIndex:
- removeObjectsAtArrangedObjectIndexes:
- removeObject:
– removeObjects:
I'm sure some of them use each other, but you'd have to test and see. I think it would be easier to do it the way I first proposed.
Yes, I believe you're right.
However, easiet of all is to simply turn on auto notifications for arrangedObjects (which you have to do anyway) and make the custom key dependent on arrangedObjects.
If you read the original message, that is what was first attempted. It doesn't work. It may be a bug, or it may be documented somewhere, but the way I proposed does work and is not that much harder.
