ios - iOS GameCenter のマルチプレイヤーリアルタイムマッチが毎回新しいスレッドを作成するのはなぜですか?

Question

私は非常に単純なマルチプレイヤーアプリを作成しました。これは、対戦相手を 1 人だけ見つけて 5 秒で終了させるだけです。

-(void)matchmakerViewController:(GKMatchmakerViewController *)viewController 
                   didFindMatch:(GKMatch *)match {

    [self.presentingViewController dismissModalViewControllerAnimated:YES];

    self.match = match;
    self.match.delegate = self;

    if (!self.matchStarted && self.match.expectedPlayerCount == 0)
    {
        NSLog(@"Ready to start match!");
        //[self lookupPlayers];

        // My Own Test Code Begin

        if (!self.delegate) NSLog(@"No delegate on match invite.");

        // Notify delegate match can begin
        self.matchStarted = YES;
        [self.delegate matchStarted];

        // My Own Test Code End
    }
}

AppDelegate のいくつかのメソッド:

-(void)matchStarted
{
    CCLOG(@"Match started. Delay 5 seconds...");

    [self performSelector:@selector(matchEnded) withObject:nil afterDelay:5];
}

-(void)matchEnded
{
    CCLOG(@"Match ended");

    [[GameCenterMatchHelper sharedInstance].match disconnect];
    [GameCenterMatchHelper sharedInstance].match = nil;
}

最初の試合ではすべて正常に動作します。しかし、試合が終了すると、3 つのスレッドが追加されます (実行を一時停止していることがわかります)。

スレッド com.apple.gamekitservices.gcksession.recvproc
スレッド com.apple.gamekitservices.gcksession.sendproc
スレッド com.apple.gamekitservices.eventcallback.eventcbproc

そして、2 つのマッチを開始すると、マッチ終了後にすでに 6 (3 と 3) のスレッドが存在します。そして、それがとても悪い主な理由 - アプリがクラッシュし、すべてのプレイヤーが切断されているようです.

最新の iOS 6 でのテストには、iPod touch 4g と iPad 2 を使用します。これらのスレッドは両方のデバイスで作成されます。

GCHelper とすべてのデリゲートにシングルトンクラスを使用しているためだと思いましたが、追加のスレッドが表示されるたびに、一度だけ使用する他のクラスにデリゲートを抽出しようとしました。

多分smbはどうすれば修正できるか知っていますか？

正解は、XCodeは実際のスレッド画像を表示しないということです。さまざまなスレッドが表示されますが、プロファイラーでそれらを表示しようとすると、追加のスレッドがないことがわかります。したがって、スレッドには問題はありませんが、デバッグプロセスには問題があることをお勧めします。トピックスターターとして、私はそれが閉じていると思います。皆さん、ありがとうございました。
