var soundEffect = AVAudioPlayer()

func playSound(_ buttonTag : Int){

    let path = Bundle.main.path(forResource: "note\(buttonTag)", ofType : "wav")!
    let url = URL(fileURLWithPath : path)

    do{
        soundEffect = try AVAudioPlayer(contentsOf: url)
        soundEffect?.play()
        // to stop the spound .stop()
    }catch{
        print ("file could not be loaded or other error!")
    }
}

工作在swift 4最新版本。ButtonTag是界面上按钮上的一个标签。笔记在与Main.storyboard平行的文件夹中的一个文件夹中。每个音符都被命名为note1、note2等。ButtonTag给出了被点击按钮的数字1、2等，并将其作为参数传递

import AVFoundation
var player:AVAudioPlayer!

func Play(){
    guard let path = Bundle.main.path(forResource: "KurdishSong", ofType: "mp3")else{return}
    let soundURl = URL(fileURLWithPath: path)
    player = try? AVAudioPlayer(contentsOf: soundURl)
    player.prepareToPlay()
    player.play()
    //player.pause()
    //player.stop()
}

如果代码没有产生任何错误，但你听不到声音-创建播放器作为一个实例:

   static var player: AVAudioPlayer!

对我来说，当我做这个改变时，第一个解决方案起作用了:)

这是在Swift中查找和播放音频文件的基本代码。

将音频文件添加到Xcode中，并添加下面的代码。

import AVFoundation

class ViewController: UIViewController {

   var audioPlayer = AVAudioPlayer() // declare globally

   override func viewDidLoad() {
        super.viewDidLoad()

        guard let sound = Bundle.main.path(forResource: "audiofilename", ofType: "mp3") else {
            print("Error getting the mp3 file from the main bundle.")
            return
        }
        do {
            audioPlayer = try AVAudioPlayer(contentsOf: URL(fileURLWithPath: sound))
        } catch {
            print("Audio file error.")
        }
        audioPlayer.play()
    }

    @IBAction func notePressed(_ sender: UIButton) { // Button action
        audioPlayer.stop()
    }
}

游戏风格:

文件Sfx.swift

import AVFoundation

public let sfx = Sfx.shared
public final class Sfx: NSObject {
    
    static let shared = Sfx()
    
    var apCheer: AVAudioPlayer? = nil
    // etc
    
    private override init() {
        guard let s = Bundle.main.path(forResource: "cheer", ofType: "mp3") else { print("Sfx woe"); return }
        do { apCheer = try AVAudioPlayer(contentsOf: URL(fileURLWithPath: s)) } catch { print("Sfx woe"); return }
        // etc
    }
    
    func cheer() { apCheer?.play() }
    func plonk() { apPlonk?.play() }
    func crack() { apCrack?.play() }
    // etc
}

只要吃一个……

    var apCheer: AVAudioPlayer? = nil

对于你的每一个音频刺。所以你可能有5 20 10等等。

对于每一个，简单地复制/粘贴两行初始化代码:

guard let s = Bundle.main.path(forResource: "cheer", ofType: "mp3") else { return print("Sfx woe") }
do { apCheer = try AVAudioPlayer(contentsOf: URL(fileURLWithPath: s)) } catch { return print("Sfx woe") }

然后，在任何地方，任何代码，任何文件，你都可以:

sfx.cheer()
sfx.crack()

iOS 12 - Xcode 10 beta 6 - Swift 4.2

只使用1个IBAction并将所有按钮指向该1个动作。

import AVFoundation

var player = AVAudioPlayer()

@IBAction func notePressed(_ sender: UIButton) {
    print(sender.tag) // testing button pressed tag
    let path = Bundle.main.path(forResource: "note\(sender.tag)", ofType : "wav")!
    let url = URL(fileURLWithPath : path)
    do {
        player = try AVAudioPlayer(contentsOf: url)
        player.play()
    } catch {
        print ("There is an issue with this code!")
    }
}
