Cocos 2d and Game Center (Leaderboard issue)

Question

I cant really find my answer after browsing (not a lot of topics on cocos2d with game center)

I currently have my sandbox game center set up and I am able to authenticate, but when I create the leaderboard it is launched sideways in portrait I assume. Tried rotating the view but nothing. My game runs only in landscape mode. I am running beta 3 0.99.5. Here is my code for reference.

tempVC = [[RootViewController alloc] init];

GKLeaderboardViewController *leaderboardController = [[[GKLeaderboardViewController alloc] init] autorelease];

if (leaderboardController != nil)
{
    leaderboardController.leaderboardDelegate = self;
    [[[CCDirector sharedDirector] openGLView] addSubview:tempVC.view];
    [tempVC presentModalViewController:leaderboardController animated:YES];
}

Really would appreciate any help. Getting no response from the cocos2d board.

EDIT:

Fixed by changing auto-rotation to CCDirector. Furthermore, I had issues with losing multi-touch functionality after showing gamecenter. The dismissal for the board should use this:

[tempVC dismissModalViewControllerAnimated:YES];
[tempVC.view.superview removeFromSuperview];

Thanks... I could not get my leaderboard or acheivements to dismiss and your EDIT above solved it for me! — jsherk, Jul 09 '12 at 20:36

=I had this problem and was tearing my hair out for days, but I eventually got it to work perfectly in landscape mode, no matter what way the user is holding the phone. It's a bit weird, and if anyone knows better please let me know!

1 - I have to have the view (of the controller which calls the leaderboard) in portrait, in my case done in IB

2 - It only works if you support the portrait orientation (even if it looks like landscape) -

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

3 - You then need to resize & rotate the leaderboard -

[self presentModalViewController: leaderboardController animated: YES];

leaderboardController.view.transform = CGAffineTransformMakeRotation(CC_DEGREES_TO_RADIANS(0.0f));
leaderboardController.view.bounds = CGRectMake(0, 0, 480, 320);
leaderboardController.view.center = CGPointMake(240, 160);

4 - Hey presto! It's working fine. Hope it works for you too.

Using this on cocos2d v1.0.1, latest stable version as of Apr 19th, 2012, this actually doesn't allow the vc to disappear animated. Probably running this instead:

[tempVC dismissModalViewControllerAnimated:YES];
[[[tempVC view] superview] performSelector:@selector(removeFromSuperview) withObject:nil afterDelay:1.2];
[tempVC performSelector:@selector(release) withObject:nil afterDelay:1.3];

Good answer, but as of a recent iOS update (iOS 4?) you can now use blocks in this method to be a little less hacky: `[vc dismissViewControllerAnimated:(BOOL) completion:^(void)completion];` Ex: `[tempVC dismissViewControllerAnimated:YES completion:^{ [tempVC.view removeFromSuperview]; [tempVC release]; }];` – jmosesman Jul 03 '12 at 05:15

The correct was is to implement and include this category:

.h

#import <GameKit/GameKit.h>

@interface GKLeaderboardViewController (additions)
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation;
-(NSUInteger)supportedInterfaceOrientations;
@end

.m

#import "GKLeaderboardViewController+additions.h"

@implementation GKLeaderboardViewController (additions)
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
    return UIInterfaceOrientationIsLandscape(toInterfaceOrientation);
}
-(NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskLandscape;
}
@end

You might want to make the same category on `GKGameCenterViewController`, `GKAchievementViewController` and the match making controller. — Jonny, Jun 10 '13 at 06:36

if it might help, I have found that simply removing the GKLeaderboard from the superview is not really enough, so after you use

[tempVC.view.superview removeFromSuperview];

you should also use

[tempVC release];

Without this the GKLeaderboardViewController is doing some weird things, like after the second call it is not auto rotating itself in the view.

I hope it help

Had the same problem with GC launching in portrait on iPad when my Cocos2D game was in landscape. Fixed this by deriving my GameKit controller from rootViewController instead of UIViewController.

@interface GCController :RootViewController {

Nope didnt work for me. Same issue. It appears the actual gameCenter view is landscape turned sideways. So I have the game in landscape with a leaderboard that shows up covering less than half the screen and extends beyond the screen. (Not sure if that makes any sense?) I am at a complete loss. – Arbel Nov 07 '10 at 05:26

A GKLeaderboardViewController is used to display the default leaderboard, which is a portrait only view. To display a landscape leaderboard, you have to implement your own custom leaderboard view.

Edit: Since the initial writing of this, GKLeaderboardViewController has been improved to work just fine in any orientation.

So the one in games like Angry Birds is completely custom? Im not sure I quite understand. – Arbel Nov 01 '10 at 13:02
Angry Birds uses the Crystal SDK for its leaderboard. http://www.crystalsdk.com/ – Mr. Berna Nov 01 '10 at 13:19
Hmmm it appears this isn't entirely correct, unless you are talking about something else. After some fiddling around with the Cocos2d default rotations, I got the leaderboard to properly display in landscape mode. However my UIScrollView on the next scene was improperly displaying. No clue what is going on. – Arbel Nov 02 '10 at 10:31
How'd you manage to get the leaderboard to display in landscape mode? – jtalarico Nov 14 '10 at 00:00
It has something to do with Cocos2d auto-rotation. If I use the CCDirector autorotation, it launches the leaderboard in landscape. However, once dismissed I have other issues, like multi-touch not working anymore. If I use the default UIView rotation, the leaderboard is launched in portrait but turned sideways. No rotation efforts I make change it. – Arbel Nov 15 '10 at 15:10
