DDLog doen't output logs to Console.app

Question

I write following code in application didFinishLaunchingWithOptions

[DDLog addLogger:[DDTTYLogger sharedInstance]];
[[DDTTYLogger sharedInstance] setColorsEnabled:YES];
[DDLog addLogger:[DDASLLogger sharedInstance]];

But, it doesn't send log to Console.app.

How can I send it to console app?

Thanks for your helps.

Answer 1

Do you called below method?

[DDLog addLogger:DDFileLogger_Object];

See below code example

//For Apple's console
[DDLog addLogger:[DDASLLogger sharedInstance]];
//For terminal:
[DDLog addLogger:[DDTTYLogger sharedInstance]];

NSString* logsDirectory = [LoggerManager logsDirectory];
DDLogFileManagerDefault* logFileManager = [[DDLogFileManagerDefault alloc] initWithLogsDirectory:logsDirectory];
fileLogger = [[DDFileLogger alloc] initWithLogFileManager:logFileManager];
// Configure File Logger
[fileLogger setMaximumFileSize:MAX_FILES_SIZE];
[fileLogger setRollingFrequency:ROLLING_FREQUENCY];
[[fileLogger logFileManager] setMaximumNumberOfLogFiles:MAX_NUMBER_OF_FILES];
[DDLog addLogger:fileLogger];

For deployment target iOS 10.0, make sure you are using the new DDOSLogger like this:

[DDLog addLogger:[DDOSLogger sharedInstance]]; // Uses os_log

and not DDTTYLogger or DDASLLogger.

Swift Usage

Usually, you can simply import CocoaLumberjackSwift. If you installed CocoaLumberjack using CocoaPods, you need to use import CocoaLumberjack instead.

DDLog.add(DDOSLogger.sharedInstance) // Uses os_log

let fileLogger: DDFileLogger = DDFileLogger() // File Logger
fileLogger.rollingFrequency = 60 * 60 * 24 // 24 hours
fileLogger.logFileManager.maximumNumberOfLogFiles = 7
DDLog.add(fileLogger)

...

DDLogVerbose("Verbose")
DDLogDebug("Debug")
DDLogInfo("Info")
DDLogWarn("Warn")
DDLogError("Error")

Obj-C usage If you're using Lumberjack as a framework, you can @import CocoaLumberjack;. Otherwise, #import <CocoaLumberjack/CocoaLumberjack.h>

[DDLog addLogger:[DDOSLogger sharedInstance]]; // Uses os_log

DDFileLogger *fileLogger = [[DDFileLogger alloc] init]; // File Logger
fileLogger.rollingFrequency = 60 * 60 * 24; // 24 hour rolling
fileLogger.logFileManager.maximumNumberOfLogFiles = 7;
[DDLog addLogger:fileLogger];

...

DDLogVerbose(@"Verbose");
DDLogDebug(@"Debug");
DDLogInfo(@"Info");
DDLogWarn(@"Warn");
DDLogError(@"Error");

It seems that you're expecting issues that were fixed few days ago. Those fixes will go to 1.8.2.

Meantime, you can grab latest version from github, or use pod 'CocoaLumberjack', :head in case if you're using CocoaPods.
