setting

$ pod install

xxx-Prefix.pch

    #ifdef DEBUG
      static const int ddLogLevel = LOG_LEVEL_VERBOSE;
    #else
      static const int ddLogLevel = LOG_LEVEL_OFF;
    #endif

and add new formatfile , like CLTCustomFormatter in this sample Source .

and write in

AppDelegate

  - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
  {
      DDTTYLogger *ttyLogger = [DDTTYLogger sharedInstance];
      ttyLogger.logFormatter = [[CLTCustomFormatter alloc] init];
      [DDLog addLogger:ttyLogger];
      
      // setting log save dir.
      NSString *logPath = [NSHomeDirectory() stringByAppendingPathComponent:@"Library/Logs/"];
      DDLogFileManagerDefault *logFileManager = [[DDLogFileManagerDefault alloc] initWithLogsDirectory:logPath];
      self.fileLogger = [[DDFileLogger alloc] initWithLogFileManager:logFileManager];
      self.fileLogger.logFormatter = [[CLTCustomFormatter alloc] init];
      self.fileLogger.maximumFileSize = 10 * 1024 * 1024;
      self.fileLogger.logFileManager.maximumNumberOfLogFiles = 5;
      [DDLog addLogger:self.fileLogger];
      
      DDLogInfo(@"%@", self.fileLogger.logFileManager.logsDirectory);
  
      return YES;
  }

and use, import your new formatter and write above.

  DDLogError(@"Paper Jam!");       
  DDLogWarn(@"Low toner.");        
  DDLogInfo(@"Doc printed.");      
  DDLogDebug(@"Debugging");       
  DDLogVerbose(@"Init doc_parse"); .
