Is it possible to change the log level while the application runs?

[nemesyssoft]

In my AppDelegate.h, I did define this:

#define LOG_LEVEL_DEF ddLogLevel
@import CocoaLumberjack;
static DDLogLevel ddLogLevel = DDLogLevelAll;

In AppDelegate.m, in applicationDidFinishLaunching:, I check if I did save the log level from a previous session and then set it:

    NSNumber *logLevel = [defaults objectForKey:SAVED_LOG_LEVEL];
    if (logLevel != nil) {
        switch (logLevel.integerValue) {
            case 0:
                ddLogLevel = DDLogLevelVerbose;
                break;
                
            case 1:
                ddLogLevel = DDLogLevelDebug;
                break;
                
            case 2:
                ddLogLevel = DDLogLevelWarning;
                break;
                
            default:
                ddLogLevel = DDLogLevelError;
                break;
        }
    } else {
        ddLogLevel = DDLogLevelError;
    }

But, even though I declared my ddLogLevel static variable as extern ddLogLevel in all my other classes, my settings view controller doesn't seem to read the value of that static variable as it reads ddLogLevel being set to DDLogLevelAll.

So, what am I missing?

This would mean that you need to import AppDelegate.h in every place you use DDLogXYZ. And this in turn means that each of those headers define a new ddLogLevel. What you need to do is to declare your ddLogLevel as extern in AppDelegate.h and initialize it in AppDelegate.m.
Or even better: Create new Logging.h and Logging.m files that take care of this, removing the need to link AppDelegate.h to every place in the app that needs logging 😉

Thanks.
