我一直在開發允許多人比賽的遊戲。我之前測試過多人邀請，他們都已經工作。發送來自一個設備的請求在另一個設備上顯示一條橫幅，如果該邀請被接受，則遊戲開始。不顯示遊戲中心邀請
就在提交應用程序之前，兩個晚上，我再次測試了這個功能，發現它已經停止工作。
- (void)authenticateLocalUser:(UIViewController *)viewController :(id<GCHelperDelegate>)theDelegate
{
delegate = theDelegate;
self.presentingViewController = viewController;
if (!gameCenterAvailable) {
// Game Center is not available.
userAuthenticated = FALSE;
}
else{
GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer];
/*
The authenticateWithCompletionHandler method is like all completion handler methods and runs a block
of code after completing its task. The difference with this method is that it does not release the
completion handler after calling it. Whenever your application returns to the foreground after
running in the background, Game Kit re-authenticates the user and calls the retained completion
handler. This means the authenticateWithCompletionHandler: method only needs to be called once each
time your application is launched. This is the reason the sample authenticates in the application
delegate's application:didFinishLaunchingWithOptions: method instead of in the view controller's
viewDidLoad method.
Remember this call returns immediately, before the user is authenticated. This is because it uses
Grand Central Dispatch to call the block asynchronously once authentication completes.

//ios 6
[localPlayer setAuthenticateHandler:(^(UIViewController* viewcontroller, NSError *error) {
if (viewcontroller != nil){
userAuthenticated = FALSE;
[self.presentingViewController presentViewController: viewcontroller animated: YES completion:nil];
}
else if (localPlayer.isAuthenticated){
// Enable Game Center Functionality
userAuthenticated = TRUE;
[self checkForInvite:self.presentingViewController :delegate];
if (! self.currentPlayerID || ! [self.currentPlayerID isEqualToString:localPlayer.playerID]) {
// Current playerID has changed. Create/Load a game state around the new user.
self.currentPlayerID = localPlayer.playerID;
// get friends of local player
[localPlayer loadFriendsWithCompletionHandler:^(NSArray *friends, NSError *error) {
if (friends != nil)
{
[self loadPlayerData: friends];
}
}];
}
}
else{
userAuthenticated = FALSE;
}
[scoreHandler setGameCentreAvailable:userAuthenticated];
})];
}
}
- (void)checkForInvite :(UIViewController *)viewController :(id<GCHelperDelegate>)theDelegate
{
delegate = theDelegate;
self.presentingViewController = viewController;
NSLog(@"Invite handler installed");
[GKMatchmaker sharedMatchmaker].inviteHandler = ^(GKInvite *acceptedInvite, NSArray *playersToInvite) {
// Insert application-specific code here to clean up any games in progress.
if (acceptedInvite){
NSLog(@"Accepted");
GKMatchmakerViewController *mmvc = [[[GKMatchmakerViewController alloc] initWithInvite:acceptedInvite] autorelease];
mmvc.matchmakerDelegate = self;
[viewController presentViewController: mmvc animated: YES completion:nil];
} else if (playersToInvite) {
NSLog(@"Match Request");
GKMatchRequest *request = [[[GKMatchRequest alloc] init] autorelease];
request.minPlayers = 2;
request.maxPlayers = 2;
request.playersToInvite = playersToInvite;
GKMatchmakerViewController *mmvc = [[[GKMatchmakerViewController alloc] initWithMatchRequest:request] autorelease];
mmvc.matchmakerDelegate = self;
[viewController presentViewController: mmvc animated: YES completion:nil];
}
};
}
在Xcode調試窗口顯示以下內容：
2013-03-27 18:06:20.112 MyApp[791:907] Authentication changed: player authenticated.
2013-03-27 18:06:21.219 MyApp[791:907] Invite handler installed
Mar 27 18:06:21 Neils-iPhone MyApp[791] <Notice>: 18:06:21.356712 com.apple.GameKitServices: -[GKDiscoveryManager startAdvertisingLocalPlayer:discoveryInfo:]: I am [<nil>] [7989F444CF2BDA83] discoveryInfo [{
e = 2;
h = A42FD7FD;
}]
就是 「我是[] ...」 在上面的線顯著？
我甚至從Ray Wenderlich的網站上下載並運行了用於創建多人遊戲的教程並嘗試過。這表現出相同的問題，除非它在兩個設備上運行在前臺。即使在前臺運行，我的應用也不會顯示邀請請求。
有沒有其他人遇到過這個問題或者有什麼想法是怎麼回事？ authenticateLocalUser從在applicationDidFinishLaunching
