This question is a FAQ, but I'm going to ask it anyway. It has been well said by mmalc that "Observing a collection is not the same as observing the properties of the objects in a collection." Specifically, in that oh-so-common configuration, an NSMutableArray of MSMutableDictionary objects, if every dictionary has a key @"name", I might like to get notified thru KVO if a @"name" is changed. But there's no simple way to do that. I could register as an observe of @"name" for every one of those dictionaries, but this is hard to maintain as dictionaries are added to and removed from the array (though, as mmalc shows, it can be done).
My question is, does anyone have a *simple* approach to this common problem? (Assume I'm on iPhone OS where NSArrayController is absent.) What advice should one give a newbie on this topic?
