is NSLog() stored on the device (iPhone etc)? If so, where?

Question

Should all NSLog() calls be deleted in the final app for iTunes?

In my iOS app, I\'ve got lots of NSLog() for debug. Should I conditionally code them out before uplo

I'll answer the OP's question in the title about where the logs are stored on the device. NSLog() uses the ASL (Apple System Logger). Programmatically, you can only read the last 256 entries (which is what Xcode shows in the Organizer, for example).

However, if you want to access the full files, they are stored in:

/private/var/log/DiagnosticMessages

When you look into that directory (note: device must be Jailbroken), you'll find a long list of *.asl files.

I found a tool to parse those files, but I haven't tried it yet, so YMMV:
