Sort by firstname: case sensitive

[JonMo]

Hello,

When i use the sort method by firstnames, It creates two list differentiated by the uppercase and lowercase of the first letter of the firstname, example: Aaron Barbara Mark Victoria alfred charles jim nancy

How can i solve this case sensitivity issue? Thanks

Hello,

Here is Apple's NSSortDescriptor guide. Use case insensitive compare

Great! Thank you

addressBook.sortDescriptors = @[[NSSortDescriptor sortDescriptorWithKey:@"firstName" ascending:YES selector:@selector(caseInsensitiveCompare:)],
                                [NSSortDescriptor sortDescriptorWithKey:@"lastName" ascending:YES selector:@selector(caseInsensitiveCompare:)]];
