我的视图控制器没有加载游戏中心

Question

我正在跟着一个教程做一个游戏中心基于回合的比赛，井字游戏，我的视图控制器没有加载。它在我使用源代码的时候起作用，但不能和我从书中输入的代码一起使用。我已检查并找不到任何区别。

我确实进入了游戏中心，当我点击“播放你的回合”时，它会按钮“开始游戏”加载初始屏幕，而不是像原始代码那样，它假设为“tictactoeGameViewController”。

我将非常感谢，如果有人可以帮助我在这里:-)

这里是我的代码：

#import "ViewController.h" 
#import "tictactoeGameViewController.h" 

@interface ViewController() 

@end 

@implementation ViewController 


-(IBAction)beginGame:(id)sender { 

GKMatchRequest *match = [[GKMatchRequest alloc]init]; 
[match setMaxPlayers:2]; 
[match setMinPlayers:2]; 

GKTurnBasedMatchmakerViewController *tmvc = nil; 
tmvc = [[GKTurnBasedMatchmakerViewController alloc]initWithMatchRequest:match]; 
[tmvc setTurnBasedMatchmakerDelegate:self]; 
[self presentModalViewController:tmvc animated:YES]; 
[tmvc release]; 
[match release]; 

} 



- (void)viewDidLoad { 

[super viewDidLoad]; 

if ([GameCenterManager isGameCenterAvailable]) { 
    [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(localUserAuthenticationChanged:) name:GKPlayerAuthenticationDidChangeNotificationName object:nil]; 
    gcManager = [[GameCenterManager alloc]init]; 
    [gcManager setDelegate:self]; 
    [gcManager authenticateLocalUser]; 
} 
} 

-(void)processGameCenterAuthentication:(NSError *)error { 
if (error != nil) { 
    NSLog(@"An error occured during authentication: %@", [error localizedDescription]); 
} 
} 

-(void)localUserAuthenticationChanged:(NSNotification *)notif { 
NSLog(@"Authentication Changed: %@", notif.object); 
} 

- (void)didReceiveMemoryWarning 
{ 
[super didReceiveMemoryWarning]; 
// Dispose of any resources that can be recreated. 
} 


#pragma mark - GCTurnBasedMatchHelperDelegate 

-(void)turnBasedMatchmakerViewController:(GKTurnBasedMatchmakerViewController *)viewController didFindMatch:(GKTurnBasedMatch *)match { 

[self dismissModalViewControllerAnimated:YES]; 

tictactoeGameViewController *gameVC = [[tictactoeGameViewController alloc]init]; 
gameVC.match = match; 
[[self navigationController]pushViewController:gameVC animated:YES]; 
[gameVC release]; 

} 

-(void)turnBasedMatchmakerViewController:(GKTurnBasedMatchmakerViewController *)viewController playerQuitForMatch:(GKTurnBasedMatch *)match { 
[match participantQuitOutOfTurnWithOutcome:GKTurnBasedMatchOutcomeQuit withCompletionHandler:^(NSError *error) { 
    if (error) { 
     NSLog(@"An error occured ending match: %@", [error localizedDescription]); 
    } 
}]; 
} 

-(void)turnBasedMatchmakerViewController:(GKTurnBasedMatchmakerViewController *)viewController didFailWithError:(NSError *)error { 
NSLog(@"Turned Based Matchmaker Failed with Error: %@", [error localizedDescription]); 
} 

-(void)turnBasedMatchmakerViewControllerWasCancelled:(GKTurnBasedMatchmakerViewController *)viewController { 
[self dismissModalViewControllerAnimated:YES]; 
} 

@end

我没有找到解决办法：

的视图控制器必须是RootViewController的所以我改变了：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { 
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease]; 

// Override point for customization after application launch. 
self.viewController = [[[ViewController alloc] initWithNibName:@"ViewController" bundle:nil] autorelease]; 
self.window.rootViewController = self.viewController; 
[self.window makeKeyAndVisible]; 
return YES; 
} 

收件人：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { 

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; 

ViewController *controller = [[ViewController alloc] init]; 
self.navigationController = [[UINavigationController alloc] initWithRootViewController:controller]; 
self.window.rootViewController = self.navigationController; 
[self.window makeKeyAndVisible]; 
return YES; 
}
