Question

I know it should persist if my Core Data Model has not changed, but how safe it is ?

I’m an inhouse developer and we have 20 iPods with some information there, entered by our users. Now there’s some bug that this info can’t be exported, so we have to install a new update and export that information.

We are not going to change the Core Data Model, just some routines for export, so the NSPersistentStoreCoordinator should be the same …

We are going to pack the app and install the updates from iTunes, this will be ok and the data will be there ?????

thanks,

r.

edit:

so, the iPods were synchronaized with other iTunes, now if I want to update the app that it’s there, iTunes says that is going to delete ALL applications and their DATA, and the computer that installed them is not working now …

so , how I can install a corrected version without losing the data ?????

thanks!

If you have followed practice shown in template generated iPhone apps and copied (or created) your data in the apps Documents folder – then yes, it will still be there when you update from the App Store.
