DDLog(CocoaLumberjack) message in console

I want to replace NSLog with CocoaLumberjack, and I follow the GettingStarted, then add 

DDLogError(@"This is an error.");
DDLogWarn(@"This is a warning.");
DDLogInfo(@"This is just a message.");
DDLogVerbose(@"This is a verbose message.");

but why there is no log message in XCode's console?

Solution

  • Lumberjack is a generic logging framework. You have to config it to use one (or more) specific log outputs. E.g., for Apple's console, you have to use:

    [DDLog addLogger:[DDASLLogger sharedInstance]];

    For terminal:

    [DDLog addLogger:[DDTTYLogger sharedInstance]];
