骰子轉轉轉 - 基本題

Demo :

利用IBAction或是偵測shake動作來做骰子的切換

@IBAction func didTapChangeDiceButton(_ sender: Any) {
   self.playMusic()
   self.diceSum = 0
   for imageView in dicesImageList {
        imageView.image = UIImage(named: self.imageName.randomElement()!)
        self.sum(imageView: imageView)
    }
}
// 偵測晃動
override func motionEnded(_ motion: UIEvent.EventSubtype, with event: UIEvent?) {
   if motion == .motionShake {
      self.playMusic()
      self.diceSum = 0
      print("shake")
      for imageView in dicesImageList {
          
          imageView.image = UIImage(named: self.imageName.randomElement()!)
          self.sum(imageView: imageView)
      }
   }
}

利用AVPlayer()來播放骰子滾動的音效，先將音效檔放進project裡

func playMusic() {
     let fileUrl = Bundle.main.url(forResource: "轉動音效", withExtension: "mp3")!
     let playerItem = AVPlayerItem(url: fileUrl)
     player.replaceCurrentItem(with: playerItem)
     player.play()
 }

每次更換骰子圖片，利用if else 來判斷圖片的檔案，加總所有點數

func sum(imageView: UIImageView) {
     if imageView.image == UIImage(named: "dices_1")  {
         self.diceSum += 1
     }else if imageView.image == UIImage(named: "dices_2") {
         self.diceSum += 2
     }else if imageView.image == UIImage(named: "dices_3") {
         self.diceSum += 3
     }else if imageView.image == UIImage(named: "dices_4") {
         self.diceSum += 4
     }else if imageView.image == UIImage(named: "dices_5") {
         self.diceSum += 5
     }else if imageView.image == UIImage(named: "dices_6") {
         self.diceSum += 6
     }
     self.diceSumLabel.text = "點數：\(self.diceSum)"
}
