Iphone 如何在游戏中心接受邀请

我试图通过游戏中心实现邀请，但有一件事我不明白。好的，我已经从一个设备向另一个设备发送了邀请。然后我在接收者上有一个UIAlertView，它会问我是否愿意接受或拒绝邀请。当我接受它时，处理方式如下：

[GKMatchmaker sharedMatchmaker].inviteHandler = ^(GKInvite *acceptedInvite, NSArray *playersToInvite) 
                 {
                     // Insert application-specific code here to clean up any games in progress.
                     if (acceptedInvite)
                     {
                         GKMatchmakerViewController *mmvc = [[[GKMatchmakerViewController alloc] initWithInvite:acceptedInvite] autorelease];
                         mmvc.matchmakerDelegate = self;
                         [presentingViewController presentModalViewController:mmvc animated:YES];
                     }
                     else if (playersToInvite)
                     {
                         GKMatchRequest *request = [[[GKMatchRequest alloc] init] autorelease];
                         request.minPlayers = 2;
                         request.maxPlayers = 4;
                         request.playersToInvite = playersToInvite;

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

                     }
                 };

好吧，那太好了，但是接下来呢？发送方设备显然正在等待某种标准类型的响应，因为它还会显示一条警报，告诉我如果我点击“立即播放”，有些邀请尚未应答

那么我如何接受邀请呢？我应该发回什么样的数据（以及如何发回）？那么我在接受者方面应该做些什么呢？游戏应该在点击“接受”后立即开始，还是我应该先关闭AlertView，然后点击“立即玩”

---

说我应该选择第二种方式，但当解除警报并点击“立即播放”时，发现发送方设备仍在等待响应，并且不知道我已接受邀请。如果此时点击“Play now”（立即播放），正如我前面所说，它会显示一个警报，表示应用程序正在等待响应。如果你曾经这样做过，那么请解释我该怎么做。谢谢

根据Ray的教程，我已经成功实现了在线游戏中心比赛。您的问题的答案是：您不必向邀请设备发送任何内容。当您调用以下行时：

GKMatchmakerViewController*mmvc=[[GKMatchmakerViewController alloc]initWithMatchRequest:request]autorelease]，matchMakerVController处理连接。但是，您应该尽快编写邀请处理程序，最好使用身份验证更改方法。见我的：

-(void) authenticationChanged {

if ([GKLocalPlayer localPlayer].isAuthenticated && !userAuthenticated) {
    NSLog(@"Authentication changed: player authenticated.");
    userAuthenticated = TRUE;

    [self sendUnsentScores];

    [GKMatchmaker sharedMatchmaker].inviteHandler = ^(GKInvite *acceptedInvite, NSArray *playersToInvite){

        NSLog(@"Invite");

        if([AppDelegate mainMenuController].presentedViewController!=nil) {
            [[AppDelegate mainMenuController] dismissViewControllerAnimated:NO completion:^{

            }];
        } // if we're not on the main menu, or another game is going on.
          // this would be easier to do if you were using a navigation controller
          // where you'd just push the multiplayer menu etc.


        self.pendingInvite = acceptedInvite;
        self.pendingPlayersToInvite = playersToInvite;

        [[AppDelegate mainMenuController] presentViewController:[AppDelegate mainMenuController].multiGameMenu animated:NO completion:^{ // push the multiplayer menu

            [[AppDelegate mainMenuController].multiGameMenu duel:nil];
        }];

    };

}

如果你有兴趣，这里是决斗的方法。非常混乱的代码，但请处理：）

游戏加载后，我立即注册邀请，并致电
收到邀请时委派
所以我接到了媒人取消比赛的电话
中心控制器并创建匹配
最后，当找到匹配项时，方法
connectionStatusChanged负责呈现所有游戏的
观点、玩家和其他东西
代码如下：

我在游戏加载后立即注册邀请，并在收到邀请后致电代表：

- (void)registerInvites {
    [GKMatchmaker sharedMatchmaker].inviteHandler = ^(GKInvite *acceptedInvite, NSArray *playersToInvite) {
        self.pendingInvite = acceptedInvite;
        self.pendingPlayersToInvite = playersToInvite;
        [delegate inviteReceived];
    };
}

因此，我们接到了match maker的电话，要求其解除game center控制器并创建比赛：

- (void)inviteReceived {
    [[GCMultiplayerHelper sharedInstance] findMatchWithMinPlayers:2 maxPlayers:2 viewController:(UIViewController*)[self.superview nextResponder] delegate:self];
}


- (void)findMatchWithMinPlayers:(int)minPlayers maxPlayers:(int)maxPlayers viewController:(UIViewController *)viewController delegate:(id<GCMultiplayerHelperDelegate>)theDelegate {
    if (!gameCenterAvailable) return;

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

    [presentingViewController dismissModalViewControllerAnimated:YES];
    GKMatchmakerViewController *mmvc;

    if (pendingInvite != nil) {

        mmvc = [[[GKMatchmakerViewController alloc] initWithInvite:pendingInvite] autorelease];

    } else {

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

        mmvc = [[[GKMatchmakerViewController alloc] initWithMatchRequest:request] autorelease];    

    }

    mmvc.matchmakerDelegate = self;
    [presentingViewController presentModalViewController:mmvc animated:YES];

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

- (void)matchmakerViewController:(GKMatchmakerViewController *)viewController didFindMatch:(GKMatch *)theMatch
{
    self.match = theMatch;
    match.delegate = self;
    if (!matchStarted && match.expectedPlayerCount == 0) {
        NSLog(@"Ready to start match! - didFindMatch");
        [presentingViewController dismissModalViewControllerAnimated:YES];

        [self.delegate connectionStatusChanged:CONNECTIONSUCCESS];
    }
}

inviteHandler=^（GKIVITE*acceptedInvite，NSArray*PlayerToInvite）现在不推荐使用。查看注册邀请通知的新方法

请把下面那一段分成几段。
- (void)matchmakerViewController:(GKMatchmakerViewController *)viewController didFindMatch:(GKMatch *)theMatch
{
    self.match = theMatch;
    match.delegate = self;
    if (!matchStarted && match.expectedPlayerCount == 0) {
        NSLog(@"Ready to start match! - didFindMatch");
        [presentingViewController dismissModalViewControllerAnimated:YES];

        [self.delegate connectionStatusChanged:CONNECTIONSUCCESS];
    }
}
