NSSortDescriptor issue

Question

I am making a contact book App where I am fetching names from AddressBook and stored them in Core data and displayed the names on a table using NSFetchedResultsControl

Answer 1

You could try writing your own comparator Function

Assuming that it is sorting ManagedObjects and they all have fullName as a field, then the following may help.

[[NSSortDescriptor alloc] initWithKey:@"FullName" ascending:YES comparator:^NSComparisonResult(id obj1, id obj2) {
        return [[obj1 objectForKey:@"fullName"] compare:[obj2 objectForKey:@"fullName"] options:NSCaseInsensitiveSearch];
    }];

The advantage of this is you can also write the NSLog for each comparison and see what is happening.
