Do NSUserDefaults persist through an Update to an app in the Appstore?

Is this the case? Do NSUserDefaults get reset when you submit an update to an app on the App Store, or are they reset?

My app is crashing when updated but not crashing when downloaded fully - so I'm trying to determine what could possibly be different in the updated session to the freshly downloaded session.

Cheers, Nick.

They are usually not reset unless the user deletes the app. For basic data, NSUserDefaults is the best way to save data such as preferences, dates, strings etc. If you are looking to save images and files, the file system is a better bet.
