ios - GKTurnBasedMatch：无法获取/设置匹配结果

Question

我正在开发基于游戏中心的棋盘游戏。一切似乎都在运行，到处都有一些错误和怪癖。这些怪癖中最令人讨厌的是，在观看已结束的比赛时，似乎总是认为观看的玩家输了。

当我以赢得比赛的举动结束比赛时，我运行以下命令：

// Act if the game is over because of that move
if ([board playerHasWon:activePlayer]) {
    board.canMove = NO;
    match = [CNFTurnBasedMatchHelper sharedInstance].currentMatch;
    NSUInteger currentIndex = [match.participants indexOfObject:match.currentParticipant];
    NSUInteger nextIndex = (currentIndex == 0 ? 1 : 0);
    GKTurnBasedParticipant *nextParticipant = [match.participants objectAtIndex:nextIndex];
    match.currentParticipant.matchOutcome = GKTurnBasedMatchOutcomeWon;
    nextParticipant.matchOutcome = GKTurnBasedMatchOutcomeLost;
    [match endMatchInTurnWithMatchData:[[board stringValue] dataUsingEncoding:NSUTF8StringEncoding] completionHandler:nil];
}

但是，我怀疑真正的问题在于我对 matchOutcome 的检索。

加载比赛时，如果不是当前玩家轮到，我会运行它：

if (match.status == GKTurnBasedMatchStatusEnded) {
    // These lines get the board to show the winning line
    [board playerHasWon:1];
    [board playerHasWon:2];
    board.canMove = NO;
    if (match.currentParticipant.matchOutcome == GKTurnBasedMatchOutcomeWon) statusLabel.text = @"You won!";
    else statusLabel.text = @"You lost!";
}

好吧，我只是通过真正的布局解决了我自己的问题。

if ([((GKTurnBasedParticipant*)[match.participants objectAtIndex:0]).playerID isEqualToString:[GKLocalPlayer localPlayer].playerID]) {
    if ([board playerHasWon:1]) statusLabel.text = @"You won!";
    else statusLabel.text = @"You lost!";
}
else {
    if ([board playerHasWon:2]) statusLabel.text = @"You won!";
    else statusLabel.text = @"You lost!";
}
