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()

Swift 5“AVFoundation”\

简单的代码，没有错误处理，从本地路径播放音频

import AVFoundation
var audio:AVPlayer!

func stopAlarm() {
    // To pause or stop audio in swift 5 audio.stop() isn't working
    audio.pause()
}

func playAlarm() {
    // need to declare local path as url
    let url = Bundle.main.url(forResource: "Alarm", withExtension: "mp3")
    // now use declared path 'url' to initialize the player
    audio = AVPlayer.init(url: url!)
    // after initialization play audio its just like click on play button
    audio.play()
}

import AVFoundation


var myAudio: AVAudioPlayer!

    let path = Bundle.main.path(forResource: "example", ofType: "mp3")!
    let url = URL(fileURLWithPath: path)
do {
    let sound = try AVAudioPlayer(contentsOf: url)
    myAudio = sound
    sound.play()
} catch {
    // 
}

//If you want to stop the sound, you should use its stop()method.if you try to stop a sound that doesn't exist your app will crash, so it's best to check that it exists.

if myAudio != nil {
    myAudio.stop()
    myAudio = nil
}

对于Swift 3:

import AVFoundation

/// **must** define instance variable outside, because .play() will deallocate AVAudioPlayer 
/// immediately and you won't hear a thing
var player: AVAudioPlayer?

func playSound() {
    guard let url = Bundle.main.url(forResource: "soundName", withExtension: "mp3") else {
        print("url not found")
        return
    }

    do {
        /// this codes for making this app ready to takeover the device audio
        try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
        try AVAudioSession.sharedInstance().setActive(true)

        /// change fileTypeHint according to the type of your audio file (you can omit this)

        player = try AVAudioPlayer(contentsOf: url, fileTypeHint: AVFileTypeMPEGLayer3)

        // no need for prepareToPlay because prepareToPlay is happen automatically when calling play()
        player!.play()
    } catch let error as NSError {
        print("error: \(error.localizedDescription)")
    }
}

本地资产的最佳实践是将其放在资产中。Xcassets然后像这样加载文件:

func playSound() {
    guard let url = Bundle.main.url(forResource: "soundName", withExtension: "mp3") else {
        print("url not found")
        return
    }

    do {
        /// this codes for making this app ready to takeover the device audio
        try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
        try AVAudioSession.sharedInstance().setActive(true)

        /// change fileTypeHint according to the type of your audio file (you can omit this)

        /// for iOS 11 onward, use :
        player = try AVAudioPlayer(contentsOf: url, fileTypeHint: AVFileType.mp3.rawValue)

        /// else :
        /// player = try AVAudioPlayer(contentsOf: url, fileTypeHint: AVFileTypeMPEGLayer3)

        // no need for prepareToPlay because prepareToPlay is happen automatically when calling play()
        player!.play()
    } catch let error as NSError {
        print("error: \(error.localizedDescription)")
    }
}

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
