練習筆記49:骰子比大小+抽籤小幫手

這次的作業是用亂數做骰子比大小

在做的過程中想說順便做一個抽籤功能的頁面

有選擇障礙的時候就可以派上用場～

骰子比大小主要利用outlet collection分別儲存左右兩邊的骰子

並將兩個搖一搖button設定tag後拉到同一個IBAction,

在IBAction中再利用switch 去判斷讀取到的sender.tag是哪個button

進而改變對應方的骰子點數

最後用if else判斷當兩邊都有分數時比較兩邊的分數 並顯示獲勝玩家

以及設定平手時跳出的訊息

//丟骰子
    @IBAction func rollButton(_ sender: UIButton) {
        aWinButton.isHidden = true
        bWinButton.isHidden = true
        
        switch sender.tag{
    //L Side
        case 1:
            lSideSum = 0
            
            for i in 0..<lSideDices.count{
                let randomNumber = Int.random(in: 1...6)
                lSideDices[i].image = UIImage(systemName: "die.face.\(randomNumber)")
                lSideSum += randomNumber
            }
            lSideScoreLabel.text = "\(lSideSum)"
            
    //R Side
        case 2:
            rSideSum = 0
            for i in 0..<rSideDices.count{
                let randomNumber = Int.random(in: 1...6)
                rSideDices[i].image = UIImage(systemName: "die.face.\(randomNumber)")
                rSideSum += randomNumber
            }
            rSideScoreLabel.text = "\(rSideSum)"
        default:
            break
            
        }
    //判斷誰贏的win標示
        if lSideScoreLabel.text != " ",rSideScoreLabel.text != " "{
            if lSideSum > rSideSum{
                aWinButton.isHidden = false
            }else if lSideSum < rSideSum{
                bWinButton.isHidden = false
            }else{
                let alert = UIAlertController(title: "平手", message: "重來一次", preferredStyle: .alert)
                let tryAgain = UIAlertAction(title: "ＯＫ", style: .default)
                alert.addAction(tryAgain)
                present(alert, animated: true)
                setUI()
            }}
        
        
        
        
        
        
    }

抽籤小幫手的部分做了一個segmented control 可以依需求切換功能

填好選項後就可以用亂數去抽籤～

   //選功能類別
    @IBAction func selectType(_ sender: UISegmentedControl) {
        resultLabel.text = " "
        
        switch sender.selectedSegmentIndex{
        case 0:
            view3.isHidden = true
            areaView.frame = CGRect(x: 37, y: 201, width: 300, height: 230)
        case 1:
            view1.isHidden = false
            view2.isHidden = false
            view3.isHidden = false
            areaView.frame = CGRect(x: 37, y: 201, width: 300, height: 340)
        case 2:
            view1.isHidden = false
            view2.isHidden = false
            view3.isHidden = false
            areaView.frame = CGRect(x: 37, y: 201, width: 300, height: 340)
        default:
            break
        }
    }
    //點選抽籤按鈕
    @IBAction func help(_ sender: Any) {
        switch selection.selectedSegmentIndex{
        case 0:
                let choices = [choice1.text,choice2.text]
            resultLabel.text = choices[Int.random(in: 0...1)]
            
        case 1:
                let choices = [choice1.text,choice2.text,choice3.text]
                resultLabel.text = choices[Int.random(in: 0...2)]
            
        case 2:
                let choices = [choice1.text,choice2.text,choice3.text]
                let randomNumber1 = Int.random(in: 0...2)
                var randomNumber2 = Int.random(in: 0...2)
                while randomNumber2 == randomNumber1{
                randomNumber2 = Int.random(in: 0...2)}
                resultLabel.text = "\(choices[randomNumber1]!)&\(choices[randomNumber2]!)"
            
        default:
            break
            
        }

這兩個功能是用tab頁面做切換

我想要讓兩個頁面在切換時都能回復初始設定

一開始想說在viewDidLoad裡都設定了為甚麼還是不行

後來問了Peter才知道是要寫viewWillAppear

    override func viewWillAppear(_ animated: Bool) {
           super.viewWillAppear(animated)
        setUI()
        
        }

操作畫面：

完成～～～
