我尝试编写游戏（我使用本教程https://www.youtube.com/watch?v=LkYpoRj-7hA我是 Swift 新手）。到目前为止，这是我的代码：
import UIKit
class ViewController: UIViewController {
//Image View

@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

var plays = Dictionary<Int, Int>()
var done = false;

@IBAction func UIButtonClicked(sender : UIButton){

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:

}
}
func checkForWin(){}
func aiTurn(){}

and thats it.
就是这样。

Read the crash log output; it says:
读取崩溃日志输出；它说：
Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<_TtC13Swift_Tac_Toe14ViewController 0x7f8160ca0f00> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key ticTac01.'
由于未捕获的异常“NSUnknownKeyException”而终止应用程序，原因：“[<_TtC13Swift_Tac_Toe14ViewController 0x7f8160ca0f00> setValue:forUndefinedKey:]：此类不符合密钥 ticTac01 的键值编码。”
So the problem is that you have configured something (possibly an object in a XIB or Storyboard) to access ticTac01, which doesn't appear to be defined in your class. My guess is that that might have been an earlier name for one of the variables you dohave?
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，它似乎没有在你的类中定义。我的猜测是，这可能已经为您的一个变量是一个早期的名字也有吗？
