iOS Question

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

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 uploading to iTunes?

This is for an app for: iPhone, iPod, iPad

Thanks.

Answer

You don't have to remove all of them; in fact, they can be useful if your app crashes on a user's phone and you want them to send you a crash log. When a user syncs his/her phone, the crash log is located in the folder

~/Library/Logs/CrashReporter/MobileDevice/<DEVICE_NAME>

If you have NSLog()s you may gain useful information just as you would when debugging. As the others pointed out, don't overdo it, but it they could end up being useful.
