I’m not sure if there is a reliable way to do this while the application is executing.

You could on startup check previous log files, and delete the oldest ones if your running low on space?

Do you happen to know how to restrict the filesize of the log to prevent it from getting too large?

If you don’t redirect it, it just shows up in the console.

Thank you! This helps a lot.
I’m still puzzled about where the text goes if you don’t redirect stderr. If I’m running on the simulator, i see nothing. Does it just go to /dev/null?

You can call it whenever, but as you usually want everything to be logged, I normally do it in application:didFinishLaunchingWithOptions:

- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{

[self redirectNSLogToDocumentFolder];
return YES;
}
