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!")
    }
}

Swift 4、4.2和5

播放来自URL和项目的音频(本地文件)

import UIKit
import AVFoundation

class ViewController: UIViewController{

var audioPlayer : AVPlayer!

override func viewDidLoad() {
        super.viewDidLoad()
// call what ever function you want.
    }

    private func playAudioFromURL() {
        guard let url = URL(string: "https://geekanddummy.com/wp-content/uploads/2014/01/coin-spin-light.mp3") else {
            print("error to get the mp3 file")
            return
        }
        do {
            audioPlayer = try AVPlayer(url: url as URL)
        } catch {
            print("audio file error")
        }
        audioPlayer?.play()
    }

    private func playAudioFromProject() {
        guard let url = Bundle.main.url(forResource: "azanMakkah2016", withExtension: "mp3") else {
            print("error to get the mp3 file")
            return
        }

        do {
            audioPlayer = try AVPlayer(url: url)
        } catch {
            print("audio file error")
        }
        audioPlayer?.play()
    }

}

Swift版本:5.4及以上

import AVFoundation
var player: AVAudioPlayer?

func playSound() {
    guard let path = Bundle.main.path(forResource: "beep", ofType:"mp3") else {
        return }
    let url = URL(fileURLWithPath: path)

    do {
        player = try AVAudioPlayer(contentsOf: url)
        player?.play()
        
    } catch let error {
        print(error.localizedDescription)
    }
}

Swift 4(兼容iOS 12)

var player: AVAudioPlayer?

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 let error {
   print(error.localizedDescription)
}

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()
}

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()
    }
}
