Hi John,
You have two choices:
1. Create an NSArray of EOSortOrdering and then use the static
EOSortOrdering met hods sortArrayUsingKeyOrderArray or
sortedArrayUsingKeyOrderArray
2. Create an NSComparator and use the NSArray method
sortedArrayUsingComparator or the NSMutableArray method
sortUsingComparator
Either works, the NSComparator is perhaps a tad faster as it can
avoid some KVC but I would not let that sway my decision. I prefer
NSCompartor in most cases as I can make the NSComparator subclass an
inner class of my EO and thus keep the ordering logic there. I also
find it makes it easier to write and understand more complex orderings.

What's the best way to sort a dataset in memory using multiple fields?
I have access to Project Wonder to do it.
Thanks,
