Is there a simple way for me to store data on iPhone devices so that even if the user updates the app, the data will still be there?
For instance I have a table, in which the user is marking a page in a book he reads, I don't want this information to be lost if he updates the app. Do I save it on the app storage folder? Do I save it on documents folder? will it still be there after the update? Or do I have to go into the complication of making the app save things on the cloud? I don't need it to be there if the user is uninstalling the app and reinstalling it, it would be better this way, but even if it stays there after an update, but is deleted after a new installation it is good enough for me, any ideas?
