I think that would work; it's the approach I'd use at least... QA1159 mentions the -localizedStandardCompare: method on NSString, and the UCCompareTextDefault() C function, but I think both of those sort the wrong way around for your purposes (capitals before lowercase). My understanding is that kCFCompareForcedOrdering doesn't guarantee any *particular* ordering for items which would otherwise compare equal--- that is, there'll be a fixed ordering, but it might change in another release, or something; the specific way in which it breaks ties is not part of its specification. (Another approach would be to sort case-sensitively, and backwards, followed by a *stable* case-insensitive forwards sort. But I think this would be both more difficult to implement and slower to run than the alternative.) _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
