Question

i used the code below to show the game center but if I rotate the iPhone nothing happen and the Leaderboard will be upside-down (not respond for the orientation)

The code

// Create leaderboard view w/ default Game Center style
        GKLeaderboardViewController *leaderboardController = [[GKLeaderboardViewController alloc] init];

        // If view controller was successfully created...
        if (leaderboardController != nil)
        {
            // Leaderboard config
            leaderboardController.leaderboardDelegate = self;   // The leaderboard view controller will send messages to this object
            leaderboardController.category = category;  // Set category here
            leaderboardController.timeScope = GKLeaderboardTimeScopeAllTime;    // GKLeaderboardTimeScopeToday, GKLeaderboardTimeScopeWeek, GKLeaderboardTimeScopeAllTime

            // Create an additional UIViewController to attach the GKLeaderboardViewController to
            myViewController = [[UIViewController alloc] init];

            // Add the temporary UIViewController to the main OpenGL view
        //  [[[CCDirector sharedDirector] openGLView] addSubview:myViewController.view];
            [[[[CCDirector sharedDirector] openGLView] window] addSubview:myViewController.view];

            // Tell UIViewController to present the leaderboard
            [myViewController presentModalViewController:leaderboardController animated:YES];
            leaderboardController.view.transform = CGAffineTransformMakeRotation(CC_DEGREES_TO_RADIANS(90.0f));
            leaderboardController.view.bounds = CGRectMake(0, 0, 480, 320);
            leaderboardController.view.center = CGPointMake(160,240 );
        }

Is there any another method to show it? any help plz

Thank you

huh I found maybe a specific solution so I replace the if (leaderboardController != nil){...} by the code below.

The code :

if (leaderboardController != NULL) {
        leaderboardController.category = category; 

        leaderboardController.timeScope =GKLeaderboardTimeScopeAllTime;

        leaderboardController.leaderboardDelegate = self; 
        AppDelegate *delegate = [UIApplication sharedApplication].delegate; 

        [delegate.viewController presentModalViewController:leaderboardController animated:YES];
    }

also need to add a property for the viewController to the AppDelegate.h First add a property declaration, as shown below:

@property (nonatomic, assign) RootViewController *viewController;

Then switch to AppDelegate.m and synthesize the variable, as shown down:

@synthesize viewController;

Finally since this code uses UIKit to display a view controller, it’s best to set Cocos2D to use UIViewController rotation.
So go to GameConfig.h, comment out the current #define GAME_AUTOROTATION kGameAutorotationNone, and set it up as shown:

#define GAME_AUTOROTATION kGameAutorotationUIViewController
