I use these codes to do it .

  • (void) showAchievements
    {
    GKAchievementViewController *achievements = [[GKAchievementViewController alloc] init];
    if (achievements != NULL)
    {
    achievements.achievementDelegate = self;
    [self presentModalViewController: achievements animated: YES];
    }
    }

However, achievement for iphone comes out, not for ipad .So,how to make achievement for ipad come out?
Thank you！！！

Did you ever figure out how to do this? Please let me know, I’m having a similar issue. Where do you create the view controller?
