iOS GameCenter 授权窗口阻止 Chartboost

Question

我在 applicationDidBecomeActive 调用 Chartboost interstitial。我的游戏使用 s Game Center，有时 GC 授权窗口会在 Chartboost 间隙弹出，阻止 Chartboost 窗口。唯一的解决办法是切换到 GameCenter 并在那里登录。是否可以检查显示的授权窗口？

当屏幕上出现 Game Center 登录时阻止广告可能是一个选项!代码仅适用于 iOS6 顺便说一句

@interface ChartboostBridge : NSObject<ChartboostDelegate>
@end

@implementation ChartboostBridge 

- (BOOL)shouldDisplayInterstitial:(NSString *)location{

    NSLog(@"CB shouldDisplayInterstitial for %@",location);

    if ([location isEqualToString:@"game_launch"]) {

        if( [[GameCenterIos shared ] hasLogInView] ){

            return NO;
        }

    }

    return YES;
}

@end


@implementation GameCenterIos

- (BOOL)hasLogInView{

    return  isViewOnScreen;
}

- (void)login
{
    GKLocalPlayer* localPlayer = [GKLocalPlayer localPlayer];
    if (localPlayer.isAuthenticated) {
        isViewOnScreen=NO;
        return;
    }

    localPlayer.authenticateHandler =
        ^(UIViewController *viewController,
    NSError *error) {


        if (localPlayer.authenticated) {
            isAuthenticated = YES;
            isViewOnScreen=NO;
        } else if(viewController) {
            NSLog(@"Game Center shows login ....");
            isViewOnScreen=YES;
            [self presentViewController:viewController];
        } else {
            NSLog(@"Game Center error or canceled login ....");
            //User canceled Login view
            isAuthenticated = NO;
            isViewOnScreen=NO;
        }
    };
}

#pragma mark UIViewController stuff

-(UIViewController*) getRootViewController {
    return [UIApplication 
        sharedApplication].keyWindow.rootViewController;
}

-(void)presentViewController:(UIViewController*)vc {
    UIViewController* rootVC = [self getRootViewController];
    [rootVC presentViewController:vc animated:YES 
        completion:nil];
}

@end
