GKMatchmakerViewController未在iOS 7中打開，但在iOS 5.1中工作

Question

我按照本教程http://www.raywenderlich.com/3276/how-to-make-a-simple-multiplayer-game-with-game-center-tutorial-part-12，但匹配窗口未打開。的源代碼的DropBox鏈路https://www.dropbox.com/s/e4pp95iqqo6xkrw/testCocos2d%202.zip

- (void)findMatchWithMinPlayers:(int)minPlayers maxPlayers:(int)maxPlayers viewController:(UIViewController *)viewController delegate:(id<GCHelperDelegate>)theDelegate { 

    if (!gameCenterAvailable) return; 

    matchStarted = NO; 
    self.match = nil; 
    self.presentingViewController = viewController; 
    delegate = theDelegate; 

    if (pendingInvite != nil) { 

     [presentingViewController dismissModalViewControllerAnimated:NO]; 
     GKMatchmakerViewController *mmvc = [[[GKMatchmakerViewController alloc] initWithInvite:pendingInvite] autorelease]; 
     mmvc.matchmakerDelegate = self; 
     [presentingViewController presentModalViewController:mmvc animated:YES]; 

     self.pendingInvite = nil; 
     self.pendingPlayersToInvite = nil; 

    } else { 
     GKMatchRequest *request = [[[GKMatchRequest alloc] init] autorelease]; 
     request.minPlayers = minPlayers; 
     request.maxPlayers = maxPlayers; 
     request.playersToInvite = pendingPlayersToInvite; 

     GKMatchmakerViewController *mmvc = [[[GKMatchmakerViewController alloc] initWithMatchRequest:request] autorelease]; 
     mmvc.matchmakerDelegate = self; 
     [presentingViewController presentViewController:mmvc animated:YES completion:nil]; 
     self.pendingInvite = nil; 
     self.pendingPlayersToInvite = nil; 

    } 

} 

如果我使用本然後應用程序在IOS 6和上述BT犯規打開GKMatchmakerViewController

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{ 
    // Init the window 
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; 
    CCDirector *director = [CCDirector sharedDirector]; 
    EAGLView *glView = [EAGLView viewWithFrame:[self.window bounds] 
            pixelFormat:kEAGLColorFormatRGB565 // kEAGLColorFormatRGBA8 
            depthFormat:0      // GL_DEPTH_COMPONENT16_OES 
    ]; 
    // attach the openglView to the director 
    [director setOpenGLView:glView]; 
    // // Enables High Res mode (Retina Display) on iPhone 4 and maintains low res on all other devices 
    if(! [director enableRetinaDisplay:YES]) 
     CCLOG(@"Retina Display Not supported"); 
    [director setAnimationInterval:1.0/60]; 
    // make the OpenGLView a child of the view controller 
    [viewController setView:glView]; 
    // make the View Controller a child of the main window 
    self.window.rootViewController = viewController; 
    if(! [director enableRetinaDisplay:YES]) 
     CCLOG(@"Retina Display Not supported"); 
    // Create a Navigation Controller with the Director 
    UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:director]; 
    navController.navigationBarHidden = YES; 
    NSString *reqSysVer = @"6.0"; 
    NSString *currSysVer = [[UIDevice currentDevice] systemVersion]; 
    if ([currSysVer compare:reqSysVer options:NSNumericSearch] != NSOrderedAscending) 
    { 
     [self.window setRootViewController:navController]; 
    } else 
    { 
     [self.window addSubview: navController.view]; 
    } 
    [self.window makeKeyAndVisible]; 
    [CCTexture2D setDefaultAlphaPixelFormat:kCCTexture2DPixelFormat_RGBA8888]; 
    // Removes the startup flicker 
    [self removeStartupFlicker]; 

    [[GCHelper sharedInstance] authenticateLocalUser]; 


    // Run the intro Scene 
    [[CCDirector sharedDirector] runWithScene: [HelloWorldLayer scene]]; 
} 

如果我使用本然後應用在IOS 6崩潰向上運行並以上，但開放GKMatchmakerViewController

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{ 
    // Init the window 
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; 
    CCDirector *director = [CCDirector sharedDirector]; 
    EAGLView *glView = [EAGLView viewWithFrame:[self.window bounds] 
            pixelFormat:kEAGLColorFormatRGB565 // kEAGLColorFormatRGBA8 
            depthFormat:0      // GL_DEPTH_COMPONENT16_OES 
    ]; 
    // attach the openglView to the director 
    [director setOpenGLView:glView]; 
    // // Enables High Res mode (Retina Display) on iPhone 4 and maintains low res on all other devices 
    if(! [director enableRetinaDisplay:YES]) 
     CCLOG(@"Retina Display Not supported"); 
    [director setAnimationInterval:1.0/60]; 
    // make the OpenGLView a child of the view controller 
    [viewController setView:glView]; 
    // make the View Controller a child of the main window 
    self.window.rootViewController = viewController; 
    if(! [director enableRetinaDisplay:YES]) 
     CCLOG(@"Retina Display Not supported"); 
    // Create a Navigation Controller with the Director 
    UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:director]; 
    navController.navigationBarHidden = YES; 
    NSString *reqSysVer = @"6.0"; 
    NSString *currSysVer = [[UIDevice currentDevice] systemVersion]; 
    if ([currSysVer compare:reqSysVer options:NSNumericSearch] != NSOrderedAscending) 
    { 
     [self.window setRootViewController:navController]; 
    } else 
    { 
     [self.window addSubview: navController.view]; 
    } 
    [self.window makeKeyAndVisible]; 
    [CCTexture2D setDefaultAlphaPixelFormat:kCCTexture2DPixelFormat_RGBA8888]; 
    // Removes the startup flicker 
    [self removeStartupFlicker]; 

    [[GCHelper sharedInstance] authenticateLocalUser]; 


    // Run the intro Scene 
    [[CCDirector sharedDirector] runWithScene: [HelloWorldLayer scene]]; 
} 

用戶認證的代碼

- (void)authenticateLocalUser { 

    if (!gameCenterAvailable) return; 

    NSLog(@"Authenticating local user..."); 
    if ([GKLocalPlayer localPlayer].authenticated == NO) { 
     [[GKLocalPlayer localPlayer] authenticateWithCompletionHandler:nil]; 
    } else { 
     NSLog(@"Already authenticated!"); 
    } 
}

好吧，幾個月前我遇到了同樣的問題，我解決這個問題的方式是將mmvc作爲模態視圖控制器。請嘗試替換您的其他東西，如下所示：

[presentingViewController dismissModalViewControllerAnimated:NO]; 
GKMatchRequest *request = [[[GKMatchRequest alloc] init] autorelease]; 
request.minPlayers = minPlayers; 
request.maxPlayers = maxPlayers; 
request.playersToInvite = pendingPlayersToInvite; 

GKMatchmakerViewController *mmvc = [[[GKMatchmakerViewController alloc] initWithMatchRequest:request] autorelease]; 
mmvc.matchmakerDelegate = self; 
[presentingViewController presentModalViewController:mmvc animated:YES]; 

self.pendingInvite = nil; 
self.pendingPlayersToInvite = nil; 

此外，您的身份驗證似乎存在問題。你的方法應該使用新的玩家身份驗證機制，如：

- (void)authenticateLocalUser { 

    if (!gameCenterAvailable) return; 

    NSLog(@"Authenticating local user..."); 
    if ([GKLocalPlayer localPlayer].authenticated == NO) { 

     // Use new authentication mechanism if the iOS version is 6.0 or above 
     if ([[UIDevice currentDevice].systemVersion compare:@"6.0" options:NSNumericSearch] != NSOrderedAscending) { 
      [[GKLocalPlayer localPlayer] setAuthenticateHandler:^(UIViewController *vc, NSError *error) { 
       if (error) 
        NSLog(@"Error in authenticating User - %@", [error localizedDescription]); 
       else if (vc) { 
        AppDelegate *appDel = (AppDelegate *)[UIApplication sharedApplication].delegate; 
        [appDel.navigationController presentModalViewController:vc animated:YES]; 
       } 
      }]; 
     } 
     else 
      [[GKLocalPlayer localPlayer] authenticateWithCompletionHandler:nil]; 
    } 
    else { 
     NSLog(@"Already authenticated!"); 
    } 
}
