Создание и воспроизведение звука в Swift

Question

Создание и воспроизведение звука в Swift

Итак, что я хочу сделать, это создать и воспроизвести звук в swift, который будет воспроизводиться при нажатии кнопки, я знаю, как это сделать в Objective-C, но кто-нибудь знает, как в Swift?

Это было бы так для Objective-C:

NSURL *soundURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"mysoundname" ofType:@"wav"]];

AudioServicesCreateSystemSoundID((__bridge CFURLRef)soundURL, &mySound);

а потом играть в нее я бы сделал:

AudioServicesPlaySystemSound(Explosion);

кто-нибудь знает как я могу это сделать?

вот немного кода, который я добавил в FlappySwift, который работает:

import SpriteKit
import AVFoundation

class GameScene: SKScene {

    // Grab the path, make sure to add it to your project!
    var coinSound = NSURL(fileURLWithPath: Bundle.main.path(forResource: "coin", ofType: "wav")!)
    var audioPlayer = AVAudioPlayer()

    // Initial setup
    override func didMoveToView(view: SKView) {
        audioPlayer = AVAudioPlayer(contentsOfURL: coinSound, error: nil)
        audioPlayer.prepareToPlay()
    }

    // Trigger the sound effect when the player grabs the coin
    func didBeginContact(contact: SKPhysicsContact!) {
        audioPlayer.play()
    }

}

это похоже на некоторые другие ответы, но, возможно, немного более "быстрый":
// Load "mysoundname.wav"
if let soundURL = Bundle.main.url(forResource: "mysoundname", withExtension: "wav") {
    var mySound: SystemSoundID = 0
    AudioServicesCreateSystemSoundID(soundURL as CFURL, &mySound)
    // Play
    AudioServicesPlaySystemSound(mySound);
}
обратите внимание, что это тривиальный пример, воспроизводящий эффект код в вопрос. Вам нужно будет убедиться, что import AudioToolbox, плюс общий шаблон для такого рода кода будет загружать ваши звуки, когда ваше приложение запускается, сохраняя их в SystemSoundID переменные экземпляра где-то, используйте их во всем вашем приложении, а затем позвоните AudioServicesDisposeSystemSoundID когда вы закончите с ними.

удобный Swift расширение:
import AudioToolbox

extension SystemSoundID {
    static func playFileNamed(fileName: String, withExtenstion fileExtension: String) {
        var sound: SystemSoundID = 0
        if let soundURL = NSBundle.mainBundle().URLForResource(fileName, withExtension: fileExtension) {
            AudioServicesCreateSystemSoundID(soundURL, &sound)
            AudioServicesPlaySystemSound(sound)
        }
    }
}
затем, из любого места в вашем приложении (не забудьте import AudioToolbox), вы можете позвонить
SystemSoundID.playFileNamed("sound", withExtenstion: "mp3")
для воспроизведения "sound. mp3"

Это создает SystemSoundID из файла под названием Cha-Ching.aiff.

import AudioToolbox

let chaChingSound: SystemSoundID = createChaChingSound()

class CashRegisterViewController: UIViewController {
    override func viewWillAppear(animated: Bool) {
        super.viewWillAppear(animated)
        AudioServicesPlaySystemSound(chaChingSound)
    }
}

func createChaChingSound() -> SystemSoundID {
    var soundID: SystemSoundID = 0
    let soundURL = CFBundleCopyResourceURL(CFBundleGetMainBundle(), "Cha-Ching", "aiff", nil)
    AudioServicesCreateSystemSoundID(soundURL, &soundID)
    CFRelease(soundURL)
    return soundID
}

С классом & AudioToolbox:

import AudioToolbox

class Sound {

    var soundEffect: SystemSoundID = 0
    init(name: String, type: String) {
        let path  = NSBundle.mainBundle().pathForResource(name, ofType: type)!
        let pathURL = NSURL(fileURLWithPath: path)
        AudioServicesCreateSystemSoundID(pathURL as CFURLRef, &soundEffect)
    }

    func play() {
        AudioServicesPlaySystemSound(soundEffect)
    }
}

использование:

testSound = Sound(name: "test", type: "caf")
testSound.play()

этот код работает для меня. Используйте Try and Catch для AVAudioPlayer

import UIKit
import AVFoundation
class ViewController: UIViewController {

    //Make sure that sound file is present in your Project.
    var CatSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("Meow-sounds.mp3", ofType: "mp3")!)
    var audioPlayer = AVAudioPlayer()

    override func viewDidLoad() {
        super.viewDidLoad()

        do {

            audioPlayer = try AVAudioPlayer(contentsOfURL: CatSound)
            audioPlayer.prepareToPlay()

        } catch {

            print("Problem in getting File")

        }      
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    @IBAction func button1Action(sender: AnyObject) {

        audioPlayer.play()
    }
}

var mySound = NSSound(named:"Morse.aiff")
mySound.play()
"Морзе.aiff " - это системный звук OSX, но если вы просто нажмете на "named" в XCode, вы сможете просмотреть (в панели QuickHelp), где эта функция выполняет поиск звуков. Он может быть в папке "Supporting files"

Roman Safin · Accepted Answer · 2015-12-07 11:27:39

в соответствии с новым Swift 2.0 мы должны использовать do try catch. Код будет выглядеть так:
var badumSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("BadumTss", ofType: "mp3"))
var audioPlayer = AVAudioPlayer()
 do {
     player = try AVAudioPlayer(contentsOfURL: badumSound)
 } catch {
     print("No sound found by URL:\(badumSound)")
 }
 player.prepareToPlay()

это работает с Swift 4 :

if let soundURL = Bundle.main.url(forResource: "note3", withExtension: "wav") {
                var mySound: SystemSoundID = 0
                AudioServicesCreateSystemSoundID(soundURL as CFURL, &mySound)
                // Play
                AudioServicesPlaySystemSound(mySound);
            }

давайте рассмотрим более обновленный подход к этому вопросу:

Import AudioToolbox

func noteSelector(noteNumber: String) {

    if let soundURL = Bundle.main.url(forResource: noteNumber, withExtension: "wav") {
        var mySound: SystemSoundID = 0
        AudioServicesCreateSystemSoundID(soundURL as CFURL, &mySound)
        AudioServicesPlaySystemSound(mySound)
}

решение Мэтта Гибсона работало для меня, вот версия swift 3.
if let soundURL = Bundle.main.url(forResource: "ringSound", withExtension: "aiff") {
  var mySound: SystemSoundID = 0
  AudioServicesCreateSystemSoundID(soundURL as CFURL, &mySound)
  AudioServicesPlaySystemSound(mySound);
}

Swift 4

import UIKit
import AudioToolbox

class ViewController: UIViewController{

var sounds : [SystemSoundID] = [1, 2, 3, 4, 5, 6, 7]

override func viewDidLoad() {
    super.viewDidLoad()

    for index in 0...sounds.count-1 {
        let fileName : String = "note\(sounds[index])"

        if let soundURL = Bundle.main.url(forResource: fileName, withExtension: "wav") {
            AudioServicesCreateSystemSoundID(soundURL as CFURL, &sounds[index])
        }
    }
}



@IBAction func notePressed(_ sender: UIButton) {
    switch sender.tag {
    case 1:
        AudioServicesPlaySystemSound(sounds[0])
    case 2:
        AudioServicesPlaySystemSound(sounds[1])
    case 3:
        AudioServicesPlaySystemSound(sounds[2])
    case 4:
        AudioServicesPlaySystemSound(sounds[3])
    case 5:
        AudioServicesPlaySystemSound(sounds[4])
    case 6:

работает в Xcode 9.2

if let soundURL = Bundle.main.url(forResource: "note1", withExtension: "wav") {
   var mySound: SystemSoundID = 0
   AudioServicesCreateSystemSoundID(soundURL as CFURL, &mySound)

используйте эту функцию, чтобы сделать звук в Swift (вы можете использовать эту функцию, где вы хотите сделать звук.)

Сначала добавьте SpriteKit и AVFoundation Framework.
import SpriteKit
import AVFoundation
 func playEffectSound(filename: String){
   runAction(SKAction.playSoundFileNamed("\(filename)", waitForCompletion: false))
 }// use this function to play sound

playEffectSound("Sound File Name With Extension")
// Example :- playEffectSound("BS_SpiderWeb_CollectEgg_SFX.mp3")

        // Do any additional setup after loading the view, typically from a nib.
        audioFilePathURL = NSBundle.mainBundle().URLForResource("MetalBell", withExtension: "wav")

        AudioServicesCreateSystemSoundID( audioFilePathURL, &soundSystemServicesId)


    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.

на Swift 3:

extension SystemSoundID {
    static func playFileNamed(_ fileName: String, withExtenstion fileExtension: String) {
        var sound: SystemSoundID = 0
        if let soundURL = Bundle.main.url(forResource: fileName, withExtension: fileExtension) {
            AudioServicesCreateSystemSoundID(soundURL as CFURL, &sound)
            AudioServicesPlaySystemSound(sound)
        }
    }
}
