Question

老实说，我无法弄清楚我做错了什么。我已经尝试了我能想到的每一个解决方案。老实说，我希望这很简单。无论如何，这是我目前的代码

@IBOutlet var tacScore: UILabel!
@IBOutlet var ticScore: UILabel!

var winCounter = 0

if gameState[combination[0]] == 1 {
  winnerLabel.text = "Tac Wins!"
  ticScore.text = "Tic:\(winCounter += 1)"
} else {
  winnerLabel.text = "Tic Wins!"
  ticScore.text = "Tic:\(winCounter += 1)"
}

我根本没有收到任何错误，但当有人在我的游戏中获胜时，得分标签也会改变Tic:()和Tac:()

Answer 1

您的代码应该是这样的：

var winCounter = 0

if gameState[combination[0]] == 1 {
    winnerLabel.text = "Tac Wins!"
    winCounter += 1
    tacScore.text = "Tic:\(winCounter)"
}else{
    winnerLabel.text = "Tic Wins!"
    winCounter += 1
    ticScore.text = "Tic:\(winCounter)"
}

这里的原因是表达式将在返回到.text指针的字符串后执行。您需要做的就是先计算它，然后更新标签。
