Re: NSArrayController and the single NSMutableArray

Surely addObject: qualifies as "one of the key-value-coding-compliant array mutation methods"? (Or do I really have to -willChange:valuesAtIndexes:forKey every time I touch the NSMutableArray??)


I haven't played with this particular issue on Tiger yet, but Panther required that do some special things to make this work. Two of the more popular options are:

1. Implement indexed accessors for the key:
<http://developer.apple.com/documentation/Cocoa/Conceptual/KeyValueCoding/Concepts/AccessorConventions.html#//apple_ref/doc/uid/20002174-178830-BAJEDEFB>

2. Use the array proxy returned from -mutableArrayValueForKey: instead of the array itself. This approach is much cleaner in my opinion, but it is possibly slower than the other.
