NSUserDefaults を使用します。

// Code used to save your highscore in the preference
int topscore  = yourGameScore;
[[NSUserDefaults standardUserDefaults] setObject:[NSNumber numberWithInt:topscore] forKey:@"topscore"];
[[NSUserDefaults standardUserDefaults] synchronize];


// Code used to get your saved value from the prefs.
topScore = [[[NSUserDefaults standardUserDefaults] objectForKey:@"topscore"] intValue ];
