Question

我目前正在关注The Swift Guy的Tic Tac Toe游戏教程（https://www.youtube.com/watch?v=rD3uqeLdal8），而且我真的遇到了代码问题。

虽然游戏确定是否有平局（平局），但有时当所有空间都被放在棋盘上并且赢得胜利时，游戏会说它真的是一个平局，十字架或者应该获胜。它没有注册胜利。如果有人能帮助我，我将不胜感激。

var activePlayer = 1 //Cross
var gameState = [0, 0, 0, 0, 0, 0, 0, 0, 0]

let winningCombinations = [[0, 1, 2], [3, 4, 5], [6, 7, 8], [0, 3, 6], [1, 4, 7], [2, 5, 8], [0, 4, 8], [2, 4, 6]]
var gameIsActive = true


@IBOutlet weak var label: UILabel!



@IBAction func action(_ sender: AnyObject)
{
    if (gameState[sender.tag-1] == 0 && gameIsActive == true)
    {
        gameState[sender.tag-1] = activePlayer

        if (activePlayer == 1)
        {
            sender.setImage(UIImage(named: "Cross.png"), for: UIControlState())
            activePlayer = 2
        }
        else
        {
            sender.setImage(UIImage(named: "Nought.png"), for: UIControlState())
            activePlayer = 1
        }
    }

    for combination in winningCombinations
    {
        if gameState[combination[0]] != 0 && gameState[combination[0]] == gameState[combination[1]] && gameState[combination[1]] == gameState[combination[2]]
        {
            gameIsActive = false

            if gameState[combination[0]] == 1
            {
                label.text = "CROSS HAS WON!"
            }
            else
            {
                label.text = "NOUGHT HAS WON!"
            }

            playAgainButton.isHidden = false
            label.isHidden = false
        }
    }

    gameIsActive = false

    for i in gameState
    {
        if i == 0
        {
            gameIsActive = true
            break
        }
    }

    if gameIsActive == false
    {

            label.text = "IT WAS A DRAW"
            label.isHidden = false
            playAgainButton.isHidden = false
        }

}

由于获胜组合的数组，我发现获胜检测的代码有点过载。我在大学的iOS课程上也有同样的任务，并想出了这个。我的游戏场都设置为0 Player1 = X. Player2 = O

当他们找到这篇文章时，也许它会帮助一些人。

func checkRow(theRow: Int) -> String {
    if gameField[theRow][0] != "0" {
        let checkThisPlayer: String = gameField[theRow][0]
        if gameField[theRow][1] == checkThisPlayer &&
            gameField[theRow][2]  == checkThisPlayer {
            return checkThisPlayer
        }
    }
    return "0"
}

func checkColumn(theColumn: Int) -> String {
    if gameField[0][theColumn] != "0" {
        let checkThisPlayer: String = gameField[0][theColumn]
        if gameField[1][theColumn] == checkThisPlayer &&
            gameField[2][theColumn]  == checkThisPlayer {
            return checkThisPlayer
        }
    }
    return "0"
}

func checkDiagonal() -> String {
    if gameField[0][0] != "0" {
        let checkThisPlayer: String = gameField[0][0]
        if gameField[1][1] == checkThisPlayer &&
            gameField[2][2]  == checkThisPlayer {
            return checkThisPlayer
        }
    } else if gameField[0][2] != "0" {
        let checkThisPlayer: String = gameField[0][2]
        if gameField[1][1] == checkThisPlayer &&
            gameField[2][0]  == checkThisPlayer {
            return checkThisPlayer
        }
    }
    return "0"
}

func playerWon() -> String {
    //TODO Implement Draw check
    var winner: String = "0"
    for index in 0...gameField.count - 1 {
        winner = checkRow(theRow: index)
        if (winner != "0") {
            break
        }
        winner = checkColumn(theColumn: index)
        if (winner != "0") {
            break
        }
    }
    if winner == "0" {
        winner = checkDiagonal()
    }
    return winner
}
