ios - 带按钮的一个 ViewController 中的多个音频文件

Question

想要在同一个中播放多个音频文件ViewController 。当用户点击Button1时file1.mp3应加载到 ViewController当用户点击播放时，应该播放相同的内容，并且 button2 file2.mp3应该加载并播放。

我知道如何对单个文件执行此操作，但对于多个文件，我必须创建 ViewController一次又一次，这太难了。这是我的单个文件代码

 @IBAction func buttonPressed(_ sender: UIButton) {
    if player.isPlaying {

        player.stop()
        sender.setImage(UIImage(named:"play.png"),for: .normal)
    } else {
        player.delegate = self
        player.play()
         player.numberOfLoops = 107
        sender.setImage(UIImage(named:"pause.png"),for: .normal)
    }


 }


 do {
     let audioPlayer = Bundle.main.path(forResource: "chalisa", ofType: "mp3")
     try player = AVAudioPlayer(contentsOf: NSURL(fileURLWithPath: audioPlayer!) as URL)
 }catch {
   //ERROR
 }

Answer 1

您可以使用 Tableview 列出所有歌曲名称和播放按钮用于在一个 View Controller 中使用多个音频文件

import AVFoundation

//MARK:- Variable Declaration
var player: AVAudioPlayer?    

func playMusic() {
     guard let url = Bundle.main.url(forResource: "chalisa", withExtension: "mp3") else { return }

do {
    try AVAudioSession.sharedInstance().setCategory(.playback, mode: .default)            
    try AVAudioSession.sharedInstance().setActive(true)


    player = try AVAudioPlayer(contentsOf: url, fileTypeHint: AVFileType.mp3.rawValue)

    /* iOS 10 and earlier require the following line:
    player = try AVAudioPlayer(contentsOf: url, fileTypeHint: AVFileTypeMPEGLayer3) */

    guard let player = player else { return }

    player.play()

} catch let error {
    print(error.localizedDescription)
}
}
