iOS 6 I have (or will have) a Core Data store, one entity of which has an attribute that is a French word. French collates differently than English or a naïve Unicode sort would. My application will have both English and French localizations. It is next-to-nonnegotiable that the word lists I present be sorted in French order, regardless of the current locale. There will be 74,000 instances; I'd like to have tables that narrow down by incremental prefix searches.
NSString has comparison methods that can take account of a specified locale, so if I'm working in code, I don't (I hope) have a problem. But I'd like to get ordered results from Core Data fetches. My first impression is that I could use the …comparator: versions of NSSortDescriptor, and put my localized comparison in the block. But I know Core Data is often pickier about what NSFetchRequest will do for you. The examples in the documentation are confined to …Key:ascending: descriptors. I have three questions. 1. Are block-comparator sort descriptors permitted in NSFetchRequest? 2. If so, am I setting myself up for unacceptable performance? 3. If so, can you suggest another approach? Thanks for your consideration. — F _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
