if i have a local data of an app, suppose a local highscore where i store all my score of the game.
if i release an update of the app, i loose all data.
i save data with this method:

Code:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

    NSString *documentsDirectory = [paths objectAtIndex:0];

    NSString *filename = [documentsDirectory stringByAppendingPathComponent:@"defaultStage.dat"];

    char cstr[512]={0};

    [filename getCString:cstr maxLength:512 encoding:NSASCIIStringEncoding];

    defaultStage=1;

    FILE *pFile=fopen(cstr, "wb");

//and save with fprintf

there is a way that save the data "permanently" not to loose when i reinstall, or update the app?
thanks
