DDLogFileManagerDefault

Objective-C

@interface DDLogFileManagerDefault : NSObject <DDLogFileManager>

Swift

class DDLogFileManagerDefault : NSObject, DDLogFileManager

Default log file manager.

All log files are placed inside the logsDirectory. If a specific logsDirectory isn’t specified, the default directory is used. On Mac, this is in ~/Library/Logs/<Application Name>. On iPhone, this is in ~/Library/Caches/Logs.

Log files are named "<bundle identifier> <date> <time>.log" Example: com.organization.myapp 2013-12-03 17-14.log

Archived log files are automatically deleted according to the maximumNumberOfLogFiles property.

    Declaration

    Objective-C

    - (nonnull instancetype)initWithLogsDirectory:
        (nullable NSString *)logsDirectory;

    Swift

    Declaration

    Objective-C

    - (BOOL)isLogFile:(nonnull NSString *)fileName;

    Swift

    func isLogFile(withName fileName: String) -> Bool

    If you wish to specify a common file header to use in your log files, you can set the initial log file contents by overriding logFileHeader

    Declaration

    @property (copy, readonly, nullable) NSString *logFileHeader;

    Swift

    var logFileHeader: String? { get }
