Question

I’m writing a game write now which involves saving highscores and basic data such as “soundeffects on” and “music on” onto a plist file.
However, when in the future, I need to update my game and upload a new version of the app onto users’ iphones/ipods, how will the highscores be retained? Is there a way to save specific plist files while overwriting others? Thanks in advance!

EDIT:
Is there any way to overwrite PART of a plist or merge an existing plist with a new one?

Answer 1

If you’re putting these plists in the documents directory, there’s nothing further you need to do. These files are all retained when your app is upgraded. You get the documents directory like this:

+ (NSString*) documentsPath
{
    NSArray* sysPaths = NSSearchPathForDirectoriesInDomains( NSDocumentDirectory, NSUserDomainMask, YES );
    return [sysPaths objectAtIndex:0];
}
