iOS app update, how to update plist in the bundle?

Question

Is there a way to update a modified plist file that's in the bundle through an iTunes app update?

I have an app that stores some data in a plist file in the form of an array & dictionaries. On some updates I have added to the plist file with more array items, but it seems that when the app is updated, the new plist file isn't copied/updated over unless the user deletes the app and re-installs it.

How do I get the app to update the local copy of the plist file with the new one?

Answer 1

You can't update anything that's part of the bundle. Save the plist in the documents directory if you want to be able to update it.

NSArray *arrayPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
        NSUserDomainMask, YES);
NSString *documentsDirectory = [arrayPaths objectAtIndex:0];

Files in the documents directory don't get deleted when updating an app using the store.

Versioned .plist files? E.g. MyApp-YYYYMMdd.plist
