Hi David,
I have tried all of the following three ways with the same results:
NSComparisonResult localizedCompare = [previousLetter compare:thisLetter
options:nil range:NSMakeRange(0,[previousLetter length])
locale:[[NSUserDefaults standardUserDefaults] dictionaryRepresentation]];
localizedCompare = [previousLetter localizedCompare:thisLetter];
localizedCompare = CFStringCompareWithOptions((CFStringRef)
previousLetter, (CFStringRef)thisLetter, CFRangeMake (0, CFStringGetLength
((CFStringRef) previousLetter)), kCFCompareNonliteral |
kCFCompareCaseInsensitive | kCFCompareLocalized );
The letter comes from the longer word by using the methods:
NSString *thisLetter = [[sortString substringToIndex:1] uppercaseString];
