In release mode, the values are missing. I don't know what's wrong with it. If I install the debug version first and then overwrite it with the release build, I can retrieve the values stored in debug mode. But if I uninstall completely and install the release version directly, it's empty
The values stored in NSUserDefaults are kept in a file in the app’s sandbox. If you delete the app, the sandbox is deleted too. There is no expectation that user default values will exist when freshly installing a new app.
Have a look at the NSUserDefaults registerDefaults: method. You may find it useful.
If you delete the app, the [app’s container] is deleted too.
Well, on iOS and its various child platforms. On macOS deleting an app doesn’t delete container.
MOEHsin_Canaan, What platform are you working on? And what do you mean by “uninstall completely”?
Share and Enjoy
