iphone - Game Center 对接会 GKTurnBasedMatch 有明显滞后(约 1 分钟)

Question

我正在通过 gamecenter 实现一款多人模式的回合制游戏。我有 2 台设备(1 台 ipad，1 台 iphone)在沙盒模式下进行测试，它们运行良好，但最近它开始在自动配对过程中遇到困难。在我从一个用户发送第一个回合后，另一台设备不会立即识别出该游戏，而是打开自己的新游戏。在它能够立即发现游戏在另一台设备上开始之前，配对就相当简单了。我不记得更改了与配对相关的任何部分(NSCoding、GKTurnBasedEventHandler、GKTurnBasedMatchmakerViewControllerDelegate 委托(delegate)方法等)。

现在我从一台设备发送第一回合，需要等待大约 1 分钟，以便另一台设备可以成功连接到该游戏。连接发生后，endTurnWithMatchData 调用没有任何问题，它可以在 1-2 秒内发送和接收数据。但如果用户开始一个新游戏并且不得不等待 1 分钟以便另一个用户可以连接到他的游戏，那么这将不是一个好的用户体验。有没有人在汽车配对过程中遇到明显的滞后？我还没有实现邀请，所以我无法检查。我用 NSKeyedArchiver 存档的匹配数据似乎很大，有 3396 字节，即使对于几乎没有数据的新游戏也是如此。以下是我的代码的相关部分:

GameOptionsViewController:

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

- (void)turnBasedMatchmakerViewController:(GKTurnBasedMatchmakerViewController *)viewController didFailWithError:(NSError *)error
{
    [self dismissViewControllerAnimated:YES completion:nil];
}

- (void)turnBasedMatchmakerViewController:(GKTurnBasedMatchmakerViewController *)viewController didFindMatch:(GKTurnBasedMatch *)match
{
    [self dismissViewControllerAnimated:NO completion:nil];
    self.gcMatch = match;
    [self performSegueWithIdentifier:@"GameMultiplayer" sender:self];
}

- (void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if([segue.identifier isEqualToString:@"GameMultiplayer"])
    {
        GameViewController *GameVC = (GameViewController *)segue.destinationViewController;

        [GameVC setGameMode:GAMEMODE_MULTIPLAYER_SAMEDEVICE];

        //Multiplayer game it is
        if(self.gcMatch != nil)
        {
            [GameVC setGameMode:GAMEMODE_MULTIPLAYER_GAMECENTER];
            GameVC.gcMatchDelegate = self;
            GameVC.gcMatch = self.gcMatch;
            NSLog(@"Game OVC Segue: Match ID | %@", self.gcMatch.matchID);

        }
    }
    else
    {
       ...
    }
}

GameViewController:

//This method is called according to user actions
//It's the only method I use to send data to other participant
-(void) sendCurrentGameDataWithNewTurn:(BOOL) newTurn
{
    NSLog(@"Sending game data current participant : %@", gcMatch.currentParticipant.playerID);

    //Update match data if it is corrupted anyhow
    if (gcMatch.currentParticipant == nil)
    {
    [GKTurnBasedMatch loadMatchWithID:gcMatch.matchID withCompletionHandler:^(GKTurnBasedMatch *match, NSError *error)
     {
         if (error != nil)
         {
             NSLog(@"Error :%@", error);
             return ;
         }
         [self sendCurrentGameDataWithNewTurn:newTurn];
     }];
}
else
{
    NSData *matchData = [NSKeyedArchiver archivedDataWithRootObject:game];

    //Game advances to new player, buttons are disabled
    if(newTurn)
    {
        NSLog(@"SENDING NEW TURN");

        NSUInteger currentIndex = [gcMatch.participants
                                   indexOfObject:gcMatch.currentParticipant];

        GKTurnBasedParticipant *nextParticipant;
        nextParticipant = [gcMatch.participants objectAtIndex:
                           ((currentIndex + 1) % [gcMatch.participants count])];

        [gcMatch endTurnWithNextParticipants:[NSArray arrayWithObject:nextParticipant] turnTimeout:GC_TURN_TIMEOUT matchData:matchData completionHandler:^(NSError *error) {
            NSLog(@"Sent");
            if (error) {
                NSLog(@"SNT - %@", error);
            }
        }];
    }
    else
    {
        NSLog(@"ONLY UPDATING DATA");
        [gcMatch saveCurrentTurnWithMatchData:matchData completionHandler:^(NSError *error) {
            NSLog(@"Sent");
            if (error) {
                NSLog(@"OUD - %@", error);
            }
        }];
    }
}

-(void) updateGameDataWithGCMatch
{
    //Update whole game data
    self.game = [NSKeyedUnarchiver unarchiveObjectWithData:self.gcMatch.matchData];

    //Update game ui
    ...
}

-(void) handleTurnEventForMatch:(GKTurnBasedMatch *)match didBecomeActive:(BOOL)didBecomeActive
{
    //Check if I got data for the currently active match that options vc forwarded me here, if not do some debug print and return
    if(![self.gcMatch.matchID isEqual:match.matchID])
    {
        //For debugging reasons I skip if i get info for any previous match (other player quit etc)
        NSLog(@"GCMatch matchID: %@ match matchID:  %@",self.gcMatch.matchID,match.matchID);
        return;
    }

    NSLog(@"Turn event handle");

    self.gcMatch = match;

    if([match.currentParticipant.playerID isEqualToString: [GKLocalPlayer localPlayer].playerID ])
    {
        //Disable field buttons
        [self setFieldButtonsEnabled:TRUE];
        [self turnChangeAnimationFromLeftToRight:FALSE];
    }

    [self updateGameDataWithGCMatch];
}

关于你的问题:

我自己在 Game Center 上对匹配进行了相当多的锻炼，也经常遇到延迟，这已被证明不是我的网站造成的，而是苹果游戏中心服务器造成的。

至于额外的指导:

据我所知，您目前在设备上进行匹配的方法是:

看看是否有我可以连接的比赛 --> 如果是，请求游戏数据并连接到比赛，否则开始你自己的比赛并广播比赛数据

根据我的经验，更好的做法是从 matchrequestbroadcasts 开始，等到找到第二个玩家，定义服务器设备(例如，通过游戏中心名称的较低校验和)，然后在该设备上开始游戏。
