title: Where is Logfile stored using cocoaLumberjack
body: <p>I am Using cocoaLumberjack logging framework for iOS logging.
  For storing logs in a file I used this code.</p>
  
  <pre><code>DDFileLogger* fileLogger = [[DDFileLogger alloc] init];
  fileLogger.rollingFrequency = 60 * 60 * 24; 
  fileLogger.logFileManager.maximumNumberOfLogFiles = 7;
  
  [DDLog addLogger:fileLogger];
  
  DDLogVerbose(@"hello");
  NSLog(@"hihihihihi");
  </code></pre>
  
  <p>I am unable to find where exactly the logfile generated by this code is stored.
  Can someone help me with this problem ?</p>
