我尝试编写游戏代码（我在Swift中使用本教程https://www.youtube.com/watch?v=LkYpoRj-7hA im new）。 那是我的代码到目前为止：
import UIKit
class ViewController: UIViewController {
//Image View
@IBOutlet var ticTac_A01: UIImageView = nil
@IBOutlet var ticTac_A02: UIImageView = nil
@IBOutlet var ticTac_A03: UIImageView = nil
@IBOutlet var ticTac_B01: UIImageView = nil
@IBOutlet var ticTac_B02: UIImageView = nil
@IBOutlet var ticTac_B03: UIImageView = nil
@IBOutlet var ticTac_C01: UIImageView = nil
@IBOutlet var ticTac_C02: UIImageView = nil
@IBOutlet var ticTac_C03: UIImageView = nil
//Buttons
@IBOutlet var ticTacBtn_A01: UIButton = nil
@IBOutlet var ticTacBtn_A02: UIButton = nil
@IBOutlet var ticTacBtn_A03: UIButton = nil
@IBOutlet var ticTacBtn_B01: UIButton = nil
@IBOutlet var ticTacBtn_B02: UIButton = nil
@IBOutlet var ticTacBtn_B03: UIButton = nil
@IBOutlet var ticTacBtn_C01: UIButton = nil
@IBOutlet var ticTacBtn_C02: UIButton = nil
@IBOutlet var ticTacBtn_C03: UIButton = nil
@IBOutlet var resetBtn: UIButton = nil
@IBOutlet var userMessage: UILabel = nil
var plays = Dictionary<Int, Int>()
var done = false;
var aiDeciding = false;
@IBAction func UIButtonClicked(sender : UIButton){
userMessage.hidden = true;
if !plays[sender.tag] && !aiDeciding && !done {
setImageForSpot(sender.tag, player:1)
}
checkForWin()
aiTurn()
}
func setImageForSpot(spot:Int, player:Int){
var playerMark = player == 1 ? "x" : "o"
plays[spot] = player
switch spot {
case 1:
ticTac_A01.image = UIImage(named: playerMark)
case 2:
ticTac_A02.image = UIImage(named: playerMark)
case 3:
ticTac_A03.image = UIImage(named: playerMark)
case 4:
ticTac_B01.image = UIImage(named: playerMark)
case 5:
ticTac_B02.image = UIImage(named: playerMark)
case 6:
ticTac_B03.image = UIImage(named: playerMark)
case 7:
ticTac_C01.image = UIImage(named: playerMark)
case 8:
ticTac_C02.image = UIImage(named: playerMark)
case 9:
ticTac_C03.image = UIImage(named: playerMark)
default:ticTac_B02.image = UIImage(named: playerMark)
}
}
func checkForWin(){}
func aiTurn(){}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
首先，我使用此输出获得“线程1：信号SIGABRT”：

调试后＆gt;继续我线程1：EXC_BAD_INSTRUCTION（代码= EXC_I386_INVOP，子代码= 0x0）。
就是这样。
任何人都可以帮助我吗？
答案 0 :(得分：6)
读取崩溃日志输出;它说：
由于未捕获的异常'NSUnknownKeyException'而终止应用程序，原因：'[＆lt; _TtC13Swift_Tac_Toe14ViewController 0x7f8160ca0f00＆gt; setValue：forUndefinedKey：]：此类不是密钥ticTac01的密码值编码。'
所以问题是你已经配置了一些东西（可能是XIB或Storyboard中的一个对象）来访问ticTac01，这似乎没有在你的类中定义。我的猜测是，这可能是你做的其中一个变量的早期名称？
