Hi, I used MGBlue's tutorial for Gamecenter in my version 1.5 app. I'm always getting the following errors in this section. I have three issues of expected identifier or "(" for several of my brackets. another pressing issue is that I'm getting "Initializer element is not a control time constant" for the [[GKLeaderboardViewController alloc] init]; part. Can you guys help me fix both errors? Those are the only two holding me back and I've looked everywhere...Thanks!!! //submit score -(void)submitScore{ if(totalPoints > 0) { [self.gameCenterManager reportScore: totalPoints forCategory: self.currentLeaderBoard]; } GKLeaderboardViewController *leaderboardController = [[GKLeaderboardViewController alloc] init]; if (leaderboardController != NULL) { leaderboardController.category = self.currentLeaderBoard; leaderboardController.timeScope = GKLeaderboardTimeScopeWeek; leaderboardController.leaderboardDelegate = self; [self presentModalViewController: leaderboardController animated: YES]; } } //show scoreboard -(void)showScoreboard{ GKLeaderboardViewController *leaderboardController = [[GKLeaderboardViewController alloc] init]; if (leaderboardController != NULL) { leaderboardController.category = self.currentLeaderBoard; leaderboardController.timeScope = GKLeaderboardTimeScopeWeek; leaderboardController.leaderboardDelegate = self; [self presentModalViewController: leaderboardController animated: YES];

These lines should not be on the same line: //submit score -(void)submitScore{ if(totalPoints > 0) Should be: //submit score -(void)submitScore{ if(totalPoints > 0) That may be one problem.

Thanks! That helped for three errors but I still have the "Initializer element is not a control time constant" for the [[GKLeaderboardViewController alloc] init]; part. How are you supposed to fix that? I could not find a solution so far.

Did you fix both sections? You also are commenting out this line: //show scoreboard -(void)showScoreboard{ Should be: //show scoreboard -(void)showScoreboard{

Thanks! However, now I'm getting the error "! Expected Expression" for this part of the code above: leaderboardController.category = self.currentLeaderBoard; leaderboardController.timeScope = GKLeaderboardTimeScopeWeek; leaderboardController.leaderboardDelegate = self;

I'm getting an "Expected expression problem" for this section leaderboardController.category = self.currentLeaderBoard; leaderboardController.timeScope = GKLeaderboardTimeScopeWeek; leaderboardController.leaderboardDelegate = self;

Try changing it from this: leaderboardController.category = self.currentLeaderBoard; leaderboardController.timeScope = GKLeaderboardTimeScopeWeek; leaderboardController.leaderboardDelegate = self; to this: leaderboardController.category = self.currentLeaderBoard; leaderboardController.timeScope = GKLeaderboardTimeScopeWeek; leaderboardController.leaderboardDelegate = self;

I'm still getting "Expected expression problem" just for the first line though leaderboardController.category = self.currentLeaderBoard;

All I can suggest at this point is you go back over the tutorial step by step and make sure you didn't miss anything or copy something incorrectly. It works with 1.5 and with a slight modification it works with 2.0.
