CLPlacemark - State Abbreviations?

Question

I was wondering if it was possible to get the state abbreviations from CLPlacemark?

In the CLPlacemark Reference from Apple it states:

administrativeArea The sta

Here is another category using FormattedAddressLines, it returns a result like California, CA

-(NSString *) stateWithAbbreviation {
if ([[self.addressDictionary objectForKey:@"CountryCode"] isEqualToString:@"US"] && self.addressDictionary) {
    NSDictionary *addressLines = [self.addressDictionary objectForKey:@"FormattedAddressLines"];
    for (NSString* addressLine in addressLines) {
        NSRange stateRange = [addressLine rangeOfString:self.postalCode options:NSCaseInsensitiveSearch];
        if (stateRange.length > 0) {
            NSRange lastSpace = [addressLine rangeOfString:@" " options:NSBackwardsSearch];
            if (lastSpace.length > 0) {
                NSString *state = [[addressLine substringToIndex:lastSpace.location] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
                lastSpace = [state rangeOfString:@" " options:NSBackwardsSearch];
                if (lastSpace.length > 0) {
                    NSString *abbr =  [[state substringFromIndex:lastSpace.location] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
                    return  [NSString stringWithFormat:@"%@, %@", self.administrativeArea, abbr];
                }
            }
        }
    }
}
return self.administrativeArea;
}

Not perfect but it works as long as Apple changes the format of the address lines I think.
