Using this tutorial, I have created many Quiz apps with Leaderboard in Game Center. http://www.buzztouch.com/files/howtos/Game-Center-Tutorial.pdf. I want to build a new app with including many Quizzes, each quiz posting result on different Leaderboards. I am looking for hints, code sample or tutorial to do so. Thanks

Yes, this can be done - MGoBlue (the same guy who wrote that tutorial) posted this handy block of code in a thread a while ago. You will need to paste this submitScore method over the entire submitScore method from the tutorial - //submit score -(void)submitScore{ if(totalPoints > 0) { self.currentLeaderBoard = [self.screenData itemNickname]; [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]; } } This method works by looking for a leaderboard id to match the nickname of the current screen. You will need to make sure that the screen nickname for each quiz is identical to its corresponding leaderboard id hopefully that makes sense :)

The whole thing doesn't work anymore with the latest Xcode, Buzztouch and IOS. MGoBlue is aware of that and wanted to update his tutorials. Waiting time.

Hi ! I just add the code and add some statement in AppSpecificValue.h #define kLeaderboardID @"yourlearderboradId" // for each leader board Just tested everything and it seem to work fine. Thanks Absentia !

Working on the latest Xcode, buzztouch and ios??

Yep, the majority of the tutorial still works as far as I can tell - it's just some of the BT_quiz.m stuff that needs a little tweaking

ok, so could you publish the little tweakings?

This is really the only one - http://www.buzztouch.com/forum/thread.php?tid=7D84F0940EAC024FB8FFCC6&command=isSearching&currentPage=1&topicTitle=2.0%20quiz&createdBy=&repliedBy=&minViews=-1&maxViews=-1&minReplies=-1&maxReplies=-1&forumCategory= Oh, haha I just noticed you've already been posting in that thread...what part of the tutorial are you having trouble with exactly?

I got many red errors as I was 75% through the tutorial so kinda stopped. Cant believe anyone could get this working on the newest source downloads.

What kind of errors and where are they?

will reproduce it and post it here.
