發出聲音吧！！AVFoundation 實作:木琴App 木琴 🔊

成果：

請開啟聲音🔊

練習使用Action & AVFoundation

製作流程

先下載木琴聲音匯入xcode

Storyboard ：

將button 配對每個琴鍵圖片 並命名為 木琴聲音的檔名
因為我們要透過按下的currentTitle去抓取對應的wav檔

主要程式碼：

定義一個func playsound 傳入的字串 去播放

透過按下的button抓取title 播放對應的wav檔

@IBAction func SoundButton(_ sender: UIButton) {
playSound(SoundNane: sender.currentTitle!)
sender.alpha = 0.5
DispatchQueue.main.asyncAfter(deadline: .now() + 0.2) {
sender.alpha = 1.0
}
}
func playSound(SoundNane:String) {
let url = Bundle.main.url(forResource: SoundNane, withExtension: "wav")
player = try! AVAudioPlayer(contentsOf: url!)
player?.play()
}
