Jeff,
This has a bit of a whiff about it. Two arrays of the same objects is
not unusual, but forcing them always into the same order is - surely
that's just a data duplication? If the arrays are meant to be
identical, why not just use one array? What is different?
If array B contains array A + some extra objects (which after sorting
will always be pushed to the end of the array), maybe a better pattern
would be to keep just these additional objects in array B and just
tack them on to the end of array A when a complete list is requested.
Then your problem reduces to "how do I sort an array?" which Cocoa
gives you. A bit more of an overview of what you're actually trying to
do would help.
cheers, Graham

Hey all...
I've got two arrays that are related, so that object 0 in one array
corresponds to object 0 in the other array. I'd like to implement a
sort based on the values in one array, but to reorder both array so
that the order of the two arrays stays in sync and that object x in
one array continues to correspond to the same thing as object x in
the other array after the sort.
I've got a general idea of how to implement the sort, but since I
know that there are a few places in the system where array pairs are
used like this, I wanted to see if there was any out-of-the-box way
of handling this scenario - I'd hate to reinvent the wheel if it's
not necessary. Does anyone know if there is any easy way to do this?
TIA,
Jeff
