sort NSArray alphabetically, but local language should be first and then all other

Question

I need to sort my array sectionIndexTitlesForTableView on next rules: first sort using local alphabetic (german, france or some else - current user interface) and then english sort and at the end all other symbols in section #. I'm tried to make this using sortedArrayUsingSelector:@selector(localizedCaseInsensitiveCompare:) method, but they don't help (the sort english first and then local strings). How to do this?

Answer 1

I'm not sure any of the standard comparators will do what you're asking for, but you can always write your own.

(And if you don't want to have to make a category on NSString for implementing your own comparison selector, you can always use -[NSArray sortedArrayUsingComparator:] which lets you pass a block.)
