userDefaultsで連勝している値を保存する

self.userDefaults.object(forKey: “load”) != nil　で、空判定

    let userDefaults = UserDefaults.standard

    var load = 0
    var str:String = "連勝"

    @IBOutlet weak var imageView: UIImageView!
    @IBOutlet weak var resultView: UILabel!
    @IBOutlet weak var imageView2: UIImageView!
    @IBOutlet weak var gameResult: UILabel!

    @IBAction func getGoo(_ sender: Any) {
        let results1 = ["Image1","Image2","Image3"]
        let random1 = arc4random_uniform(UInt32(results1.count))
        let image1 = UIImage(named: results1[Int(random1)])
        imageView.image = image1
        let image4 = UIImage(named: "Image4")
        imageView2.image = image4
        
        let even = "あいこ"
        let win = "あなたの勝ち"
        let lose = "あなたの負け"
        
        if random1 == 0 {
            self.gameResult.text = even
            if self.userDefaults.object(forKey: "load") != nil {
                self.load = self.userDefaults.integer(forKey: "load")
            } else {
                self.load = 0
            }
        } else if(random1 == 1){
            self.gameResult.text = win
            if self.userDefaults.object(forKey: "load") != nil {
                self.load = self.userDefaults.integer(forKey:"load")
                self.load += 1
            } else {
                self.load = 1
            }
        } else {
            self.gameResult.text = lose
            if self.userDefaults.object(forKey: "load") != nil {
                self.load = self.userDefaults.integer(forKey:"load")
                self.load -= 1
            } else {
                self.load = -1
            }
        }
        self.gameResult.text = String(self.load) + str
        UserDefaults.standard.set(self.load, forKey: "load")
        
    }

なるほど、保存できることはわかった。

負けた時に、-1連勝となるので、var str:String = “連勝”　の他に、連敗のテキストを作り、連勝中の負けの時と連敗中の勝ちの時は、load = 0 にリセットですな。

勝ちの時

if self.userDefaults.object(forKey: "load") != nil {
                if self.userDefaults.integer(forKey:"load") > 0 {
                    self.load = self.userDefaults.integer(forKey:"load")
                    self.load += 1
                } else {
                    self.load = 0
                }

負けの時

if self.userDefaults.integer(forKey:”load”) < 0 { self.load = self.userDefaults.integer(forKey:"load") self.load -= 1 } else { self.load = 0 } [/code]
