Answer 6

you can hack something up like this (this just prints pretty, but you can go ahead and split until you get the number):

+ (NSString *)getPrettyCurrentThreadDescription {
    NSString *raw = [NSString stringWithFormat:@"%@", [NSThread currentThread]];

    NSArray *firstSplit = [raw componentsSeparatedByCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"{"]];
    if ([firstSplit count] > 1) {
        NSArray *secondSplit     = [firstSplit[1] componentsSeparatedByCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"}"]];
        if ([secondSplit count] > 0) {
            NSString *numberAndName = secondSplit[0];
            return numberAndName;
        }
    }

    return raw;
}
