Question

I developed a game supports only landscape mode for upper than ios 4.3 devices.
the application has gamecenter implemented and crashed during the test on ios 6 devices because gamecenter login screen doesn’t support landscape mode in ios 6.
so I fixed the problem adding below code into appdelegate.m and got worked but now application displays totally wired(displays portrait upside down) on devices below ios6(ios5 etc)

-(NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
        return UIInterfaceOrientationMaskAll;
    else // iphone
        return UIInterfaceOrientationMaskAllButUpsideDown;
}

use
xcode:4.5
cocos2d v1.0.1

please help me to solve this problem

Add given class in your project

GKMatchmakerViewController-LandscapeOnly.h

#import <Foundation/Foundation.h>
#import <GameKit/GameKit.h>

@interface GKMatchmakerViewController(LandscapeOnly)
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation;
@end

GKMatchmakerViewController-LandscapeOnly.m


#import "GKMatchmakerViewController-LandscapeOnly.h"

@implementation GKMatchmakerViewController (LandscapeOnly)

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

@end
