What I’ve looked at:

The NSSortDescriptor looks appealing but the examples I’ve seen all require a key ( initWithKey: ). That would be fine for an array

of NSDictionaries( and is particularly nice for multiple key sorts ) but I don’t see how to make it work for an array of strings.

NSSortDescriptor *desc = [[NSSortDescriptor alloc]

initWithKey:@"desc"

ascending:YES

selector:@selector(localizedCaseInsensitiveCompare:)];

followed by: [myNSMutableArray sortUsingDescriptors:[NSArray arrayWithObject:desc]];

btw: I’ve looked at:

NSArray *sortedValues = [myNSMutableArray sortedArrayUsingSelector: @selector(localizedCaseInsensitiveCompare:)];

but that puts the sorted data in a different array which is not known to my Combobox delegate methods. I could copy the sorted array to the NSMutableArray the comboBox knows about but this feels clumsy.
