I would prefer to use an array of NSSortDescriptors to sort an array of
objects because of the new deep sorting capability using them, but I
need to access more information that the sort descriptor allows for. I
have a table of sort preference objects, each object having several
pieces of information required for sorting an array of objects located
in another table. A sort descriptor's compare selector just won't do
because I need to know which sort preference object is being used so I
can manipulate the comparison. I'm thinking of subclassing
NSSortDescriptor and adding my sort preference object to the subclass,
but I can't see a way of accessing the sort descriptor during a sort.
So, my question is if it's possible to access a sort descriptor while
sorting an array using sort descriptors? It would be nice if an
NSSortDescriptor had a context parameter like
sortUsingFunction:context: allows for and the sort descriptor's compare
selector gave access to this context.
Thanks,
Keith
