How to delete log file from saved location path.

[Subodh Kumar]

Hi,

I have integrated lumberjack framework in my application. I have changed the log file location i.e.. Document directory. I am using this code

NSFileManager *fileManager = [NSFileManager defaultManager];

NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

NSString *documentsDir = [documentPaths objectAtIndex:0];

    BOOL isDir=YES;

    if(![fileManager fileExistsAtPath:[documentsDir stringByAppendingPathComponent:@"LogFile"] isDirectory:&isDir]){

        if(![fileManager createDirectoryAtPath:[documentsDir stringByAppendingPathComponent:@"LogFile"] withIntermediateDirectories:YES attributes:nil error:nil])

            NSLog(@"Error: Create folder failed");

        

    }

    NSString *logFilePath = [documentsDir stringByAppendingPathComponent:[NSString stringWithFormat:@"LogFile"]];

    

    [DDLog addLogger:[DDASLLogger sharedInstance]];

    [DDLog addLogger:[DDTTYLogger sharedInstance]];

    

    DDLogFileManagerDefault *documentsFileManager = [[DDLogFileManagerDefault alloc]

                                                     initWithLogsDirectory:logFilePath];

    

    DDFileLogger *fileLogger = [[DDFileLogger alloc]

                                initWithLogFileManager:documentsFileManager];

    

    [fileLogger setMaximumFileSize:(1024 * 1)];

    [fileLogger setRollingFrequency:(3600.0 * 24.0)];  // roll everyday

    [[fileLogger logFileManager] setMaximumNumberOfLogFiles:5];

    [fileLogger setLogFormatter:[[DDLogFileFormatterDefault alloc]init]];

    

    [DDLog addLogger:fileLogger];

Now i want to remove oldest one log file if it created 5 log files. So if new one created then max no of log file will still 5.

Thanks

Cocoalumberjack will automatically do this for you. Try setting the  rolling frequency to 60 seconds and you will see that over 5 minutes, you will get 5 files and after 10 mins, you will still only have 5 files.

However I have found the rolling the logs does work any more in version 1.8.1 so you need to use version 1.8.0 from github.

Hi Paul,

Thanks for reply. I have downloaded 1.8.0 version. It is not working  as per my requirement. Even when i am trying to write more loges. It is creating more than 5 files and not deleting older one.. But i have to limit it unto 5.

Any suggestions.

Hi there,

Please retry this using the latest 1.9.0 release (fixed an issue with rolling). If the problem persists, please file an issue on https://github.com/CocoaLumberjack/CocoaLumberjack/issues
