Question

How do I sort Unicode (foreign) strings in my iPhone application?

Answer 1

Thanks for helping me.

localizedCaseInsensitiveCompare

this API will do the sorting with respect to localization. Otherwise strings of different languages will be treated as a unicode strings and comparison fails.

Here is the solution:

NSComparisonResult sortLocationsForStr(NSString* str1, NSString* str2, void *context)
{
    return [str1 localizedCaseInsensitiveCompare:str2];
}

[myArrayToSort sortUsingFunction:sortLocationsForStr context:nil];
