我正在尝试创建一个简单的tic tac toe游戏。不需要人工智能。我已经说到我可以点击我的UI中的按钮，他们每次都会切换。我还创建了一个checkScore（）函数。但是，我认为我的checkScore（）函数在某处有错误的逻辑，我花了两天时间试图找出它。如果用户连续获得三个，那么它应该运行winnerMessage（）函数以获得胜利。我的变量名称非常自我解释。
我的问题是，除非我在checkScore（）函数中注释掉所有“else if”语句，否则winnerMessage会在第一次单击该板时运行。请帮忙！感谢。
定义变量。
var player1 = "❌"
var player2 = "⭕️"
var currentPlayer = "❌"
let originalValue = ""
let winnerMessageTopHorizontal = "We have a winner across the top!"
let winnerMessageCenterHorizontal = "We have a winner across the center!"
let winnerMessageBottomHorizontal = "We have a winner across the bottom!"
let winnerMessageLeftVertical = "We have a winner on the left side!"
let winnerMessageCenterVertical = "We have a winner down the center!"
let winnerMessageRightVertical = "We have a winner on the right side!"
let winnerMessageDiagonal1 = "We have a winner diagonally!"
let winnerMessageDiagonal2 = "We have a winner diagonally!"
这是我创建的changePlayer（）函数。
/* function that changes from player1 to player2 (switching from X to O and O to X)*/
func changePlayer(){
if currentPlayer == player1{
print ("\(player1)")
currentPlayer = player2
}
else if currentPlayer == player2{
print ("\(player2)")
currentPlayer = player1
}
else{
NSLog ("Error. Please reset the game.")
}
}
这是我一直遇到问题的checkScore（）函数。如果你注释掉除第一个函数之外的所有函数行，那么你可以看到第一步是如何工作的。
func checkScore(){
if topLeftOutlet.currentTitle == topCenterOutlet.currentTitle && topLeftOutlet.currentTitle == topRightOutlet.currentTitle && topLeftOutlet.currentTitle != ""{
announcementArea.text = winnerMessageTopHorizontal
}
else if leftCenterOutlet.currentTitle == centerOutlet.currentTitle && leftCenterOutlet.currentTitle == rightCenterOutlet.currentTitle && leftCenterOutlet.currentTitle != ""{
announcementArea.text = winnerMessageCenterHorizontal
}
else if bottomLeftOutlet.currentTitle == bottomCenterOutlet.currentTitle && bottomLeftOutlet.currentTitle == bottomRightOutlet.currentTitle && bottomLeftOutlet.currentTitle != ""{
announcementArea.text = winnerMessageBottomHorizontal
}
else if topLeftOutlet.currentTitle == leftCenterOutlet.currentTitle && topLeftOutlet.currentTitle == bottomLeftOutlet.currentTitle && topLeftOutlet.currentTitle != ""{
announcementArea.text = winnerMessageLeftVertical
}
else if topCenterOutlet.currentTitle == centerOutlet.currentTitle && topCenterOutlet.currentTitle == bottomCenterOutlet.currentTitle && topCenterOutlet.currentTitle != ""{
announcementArea.text = winnerMessageCenterVertical
}
else if topRightOutlet.currentTitle == rightCenterOutlet.currentTitle && topRightOutlet.currentTitle == bottomRightOutlet.currentTitle && topRightOutlet.currentTitle != ""{
announcementArea.text = winnerMessageRightVertical
}
else if topLeftOutlet.currentTitle == centerOutlet.currentTitle && topLeftOutlet.currentTitle == bottomRightOutlet.currentTitle && topLeftOutlet.currentTitle != ""{
announcementArea.text = winnerMessageDiagonal1
}
else if topRightOutlet.currentTitle == centerOutlet.currentTitle && topRightOutlet.currentTitle == bottomLeftOutlet.currentTitle && topLeftOutlet.currentTitle != ""{
announcementArea.text = winnerMessageDiagonal2
}
else{
NSLog ("Keep going")
}
}
@IBOutlet weak var announcementArea: UITextField!
电路板上按钮的操作和插座。操作是当用户单击按钮时它将更改为X或O.出口用于下面的重置功能，将值重置为空。
@IBAction func topLeft(sender: UIButton) {

}
@IBOutlet weak var topLeftOutlet: UIButton!

@IBOutlet weak var rightCenterOutlet: UIButton!
@IBAction func bottomLeft(sender: UIButton) {

@IBOutlet weak var bottomCenterOutlet: UIButton!
@IBAction func bottomRight(sender: UIButton) {
sender.setTitle(currentPlayer, forState: .Normal)
changePlayer()
checkScore()
}
@IBOutlet weak var bottomRightOutlet: UIButton!
此按钮目前无用：
@IBAction func startGame(sender: UIButton) {
NSLog ("Player Started Game")
}
resetButton（）函数，当玩家点击重置按钮时重置棋盘
@IBAction func resetGame(sender: UIButton) {
NSLog ("Player Reset Game")
topLeftOutlet.setTitle(originalValue, forState: .Normal)
topCenterOutlet.setTitle(originalValue, forState: .Normal)
topRightOutlet.setTitle(originalValue, forState: .Normal)
leftCenterOutlet.setTitle(originalValue, forState: .Normal)
centerOutlet.setTitle(originalValue, forState: .Normal)
rightCenterOutlet.setTitle(originalValue, forState: .Normal)
bottomLeftOutlet.setTitle(originalValue, forState: .Normal)
bottomCenterOutlet.setTitle(originalValue, forState: .Normal)
bottomRightOutlet.setTitle(originalValue, forState: .Normal)
}
}
非常感谢你看一看。我不指望它是完美的。我只需要另一只眼睛看看我是否错过了一些明显的东西！

我找出你的问题。问题在于changeScore方法，你的按钮在开始时包含nil值，但你将它们与“”字符串进行比较，这就是为什么每次你的条件总是为真并显示赢家Message.you只需要替换所有你的条件！=“”有！= nil喜欢这个

</html>在重置方法中也在按钮标题中设置nil。 我希望它能解决你的问题
答案 1 :(得分：0)
Sumit给我的答案是解决方案的一部分。谢谢你让我朝着正确的方向前进！使其工作的方法是checkScore（）函数需要像这样编写：
func checkScore(){
if (topLeftOutlet.currentTitle == topCenterOutlet.currentTitle && topLeftOutlet.currentTitle == topRightOutlet.currentTitle && topLeftOutlet.currentTitle != originalValue && topLeftOutlet.currentTitle != nil){
announcementArea.text = winnerMessageTopHorizontal
}
if (leftCenterOutlet.currentTitle == centerOutlet.currentTitle && centerOutlet.currentTitle == rightCenterOutlet.currentTitle && leftCenterOutlet.currentTitle != originalValue && leftCenterOutlet.currentTitle != nil) {
announcementArea.text = winnerMessageCenterHorizontal
}
if (bottomLeftOutlet.currentTitle == bottomCenterOutlet.currentTitle && bottomLeftOutlet.currentTitle == bottomRightOutlet.currentTitle && bottomLeftOutlet.currentTitle != originalValue && bottomLeftOutlet.currentTitle != nil){
announcementArea.text = winnerMessageBottomHorizontal
}
if (topLeftOutlet.currentTitle == leftCenterOutlet.currentTitle && topLeftOutlet.currentTitle == bottomLeftOutlet.currentTitle && topLeftOutlet != originalValue && topLeftOutlet.currentTitle != nil){
announcementArea.text = winnerMessageLeftVertical
}
if (topCenterOutlet.currentTitle == centerOutlet.currentTitle && topCenterOutlet.currentTitle == bottomCenterOutlet.currentTitle && topCenterOutlet.currentTitle != originalValue && topCenterOutlet.currentTitle != nil){
announcementArea.text = winnerMessageCenterVertical
}
if (topRightOutlet.currentTitle == rightCenterOutlet.currentTitle && topRightOutlet.currentTitle == bottomRightOutlet.currentTitle && topRightOutlet.currentTitle != originalValue && topRightOutlet.currentTitle != nil){
announcementArea.text = winnerMessageRightVertical
}
if (topLeftOutlet.currentTitle == centerOutlet.currentTitle && topLeftOutlet.currentTitle == bottomRightOutlet.currentTitle && topLeftOutlet.currentTitle != originalValue && topLeftOutlet.currentTitle != nil){
announcementArea.text = winnerMessageDiagonal1
}
if (topRightOutlet.currentTitle == centerOutlet.currentTitle && topRightOutlet.currentTitle == bottomLeftOutlet.currentTitle && topRightOutlet.currentTitle != originalValue && topRightOutlet.currentTitle != nil){
announcementArea.text = winnerMessageDiagonal2
}
}
每个＆＃34;如果＆＃34;语句需要检查按钮标题是否不等于originalValue，它是我创建的空字符串变量。另外，和Sumit提到的一样，它需要检查按钮标题是否等于nil。
