GKTurnBasedMatch：獲取/設置比賽結果失敗

Question

我正在開發基於Game Center的棋盤游戲。 似乎一切都在運行，並且到處都有一些錯誤和怪癖。 這些怪癖中最讓人討厭的是，當觀看一場比賽已經結束時，似乎總是認為觀看者已經輸了。

當我以獲勝的棋局結束比賽時，運行以下命令：

// 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，我懷疑真正的問題出在我對matchOutcome的檢索上。

加載比賽時，如果不是當前玩家轉彎，我將運行此命令：

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，我只是通過實際布局解決了自己的問題。

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!";
}
