I would love to know how to automatically submit score as well

-(IBAction)showleaderboard:(id)sender{
GKLeaderboardViewController *leaderboardController = [[GKLeaderboardViewController alloc]init];
if (leaderboardController !=NULL) {
leaderboardController.category = self.currentLeaderboard;
leaderboardController.timeScope = GKLeaderboardTimeScopeAllTime;
leaderboardController.leaderboardDelegate = self;
[self presentModalViewController:leaderboardController animated:YES];
}
}
-(void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController *)viewController{
[self dismissModalViewControllerAnimated:YES];
[viewController release];
}
-(IBAction)showAchivementLeaderboard:(id)sender{
GKAchievementViewController *achivements = [[GKAchievementViewController alloc]init];
if (achivements !=NULL) {
achivements.achievementDelegate = self;
[self presentModalViewController:achivements animated:YES];
}
}
-(void)achievementViewControllerDidFinish:(GKAchievementViewController *)viewController{
[self dismissModalViewControllerAnimated:YES];
[viewController release];
}
self.currentLeaderboard= kEasyLeaderboardID;
if ([gameCenterManager isGameCenterAvailible]) {
self.gameCenterManager= [[[GameCenterManager alloc] init] autorelease];
[self.gameCenterManager setDelegate:self];
[self.gameCenterManager authenticateLocalUser];
}else{
UIAlertView *openURLAlert = [[ UIAlertView alloc] initWithTitle:#"Game Center turned off" message:#"You are not connected to game center." delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[openURLAlert show];
[openURLAlert release];
}

To report a score you need to use GKScore as follows;
GKScore *scoreReporter = [[GKScore alloc] initWithCategory:self.gameCategory.leaderboardString];
scoreReporter.value = score;
[scoreReporter reportScoreWithCompletionHandler:^(NSError *error) {
if (error != nil) {
[[KYTGlobals instance] storeScore:score forCategory:self.gameCategory.leaderboardString];
}
}];
The above code allocates and inits a GKScore object using the identifier that you have already set up on game center for the category that you want to report a score for. You update the value for the score and then use reportScoreWithCompletionHandler making sure to test for error so that you can archive the score and report it later.
