How to view previous instance log files?

[mjanulaitis]

When the console displays, I would like to see the previous log file and even better the previous 7 days of logs. I have configured as follows but I do not see the log contents or a way to select a previous log file:

[PTEDashboard.sharedDashboard show];
[DDLog addLogger:[DDTTYLogger sharedInstance]];
DDFileLogger *fileLogger = [[DDFileLogger alloc] init]; // File Logger
fileLogger.rollingFrequency = 60 * 60 * 24; // 24 hour rolling
fileLogger.logFileManager.maximumNumberOfLogFiles = 7;
[DDLog addLogger:fileLogger];
NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];
NSString *appVersion = [infoDict objectForKey:@"CFBundleShortVersionString"];
NSString *buildNumber = [infoDict objectForKey:@"CFBundleVersion"];
DDLogInfo(@"Starting %@ (%@)...", appVersion, buildNumber);

The console is just another logger. It is an output for logs just like Xcode's console or the file logger.
It doesn't read log files but receives messages directly from CocoaLumberjack.

To implement what you want you would need to "import" log messages from the file at startup.
