返回的数据中包含控制字符
需要进行遍历删除

    NSMutableString *mstring = [NSMutableString stringWithString:originalString];
    NSCharacterSet *controlChars = [NSCharacterSet controlCharacterSet];
    NSRange range = [originalString rangeOfCharacterFromSet:controlChars];
    while (range.location != NSNotFound){ // 包含
        [mstring deleteCharactersInRange:range]; // 删除
        range = [mstring rangeOfCharacterFromSet:controlChars]; // 遍历
    }
    return mstring;
