Créer et jouer un son en rapide

Question

Donc, ce que je veux faire, c'est créer et jouer un son dans Swift qui sera joué lorsque j'appuierai sur un bouton. Je sais comment le faire dans Objective-C, mais est-ce que quelqu'un sait comment utiliser Swift?

Ce serait comme ça pour Objective-C:

NSURL *soundURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"mysoundname" ofType:@"wav"]];
AudioServicesCreateSystemSoundID((__bridge CFURLRef)soundURL, &mySound);

Et puis pour le jouer je ferais:

AudioServicesPlaySystemSound(Explosion);

Est-ce que quelqu'un sait comment je pourrais faire ça?

Answer 1

Voici un peu de code que j'ai ajouté à FlappySwift qui fonctionne:

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()
    }

}

Answer 2

Ceci est similaire à certaines autres réponses, mais peut-être un peu plus "Swifty":

// 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);
}

Notez qu'il s'agit d'un exemple trivial reproduisant l'effet du code dans la question. Vous devrez vous assurer de import AudioToolbox, et le modèle général pour ce type de code consisterait à charger vos sons au démarrage de votre application, en les enregistrant dans des variables d'instance SystemSoundID quelque part, à les utiliser dans votre application, puis à appeler AudioServicesDisposeSystemSoundID lorsque 'fini avec eux.

Answer 3

Pratique extension Swift:

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)
        }
    }
}

Ensuite, où que vous soyez dans votre application (n'oubliez pas de import AudioToolbox), vous pouvez appeler

SystemSoundID.playFileNamed("sound", withExtenstion: "mp3")

jouer "sound.mp3"

Answer 4

Cela crée une SystemSoundID à partir d'un fichier appelé 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
}

Answer 5

Avec une classe et 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)
    }
}

Usage:

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

Answer 6

import AVFoundation

var audioPlayer = AVAudioPlayer()

class GameScene: SKScene {

    override func didMoveToView(view: SKView) {

        let soundURL = NSBundle.mainBundle().URLForResource("04", withExtension: "mp3")
        audioPlayer = AVAudioPlayer(contentsOfURL: soundURL, error: nil)
        audioPlayer.play()
    }
}

Answer 7

Ce code fonctionne pour moi. Utilisez Try and Catch pour 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()
    }
}

Answer 8

Selon la nouvelle version 2.0 de Swift, nous devrions utiliser essayer essayer. Le code ressemblerait à ceci:

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()

Answer 9

var mySound = NSSound(named:"Morse.aiff")
mySound.play()

"Morse.aiff" est un son système de OSX, mais si vous cliquez simplement sur "nommé" dans XCode, vous pourrez voir (dans le volet Aide rapide) où cette fonction recherche les sons. Cela peut être dans votre dossier "Fichiers de support"

Answer 10

cela fonctionne avec Swift 4:

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

Answer 11

Voyons une approche plus actualisée de cette question:

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)
}

Swift 4 et iOS 12

var audioPlayer: AVAudioPlayer?

override func viewDidLoad() {
    super.viewDidLoad()



}

@IBAction func notePressed(_ sender: UIButton) {

    // noise while pressing button

    _ = Bundle.main.path(forResource: "note1", ofType: "wav")

Answer 14

fonctionne en Xcode 9.2

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

Answer 15

La solution de Matt Gibson a fonctionné pour moi, voici la version Swift 3. 

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

Answer 16

Vous pouvez essayer ceci dans Swift 5.2:

func playSound() {
        let soundURL = Bundle.main.url(forResource: selectedSoundFileName, withExtension: "wav")
        do {
            audioPlayer = try AVAudioPlayer(contentsOf: soundURL!)
        }
        catch {
            print(error)
        }
        audioPlayer.play()
    }

Answer 18

Exemple de code Swift :

import UIKit
import AudioToolbox

class ViewController: UIViewController {  

override func viewDidLoad() {
    super.viewDidLoad()
}

@IBAction func notePressed(_ sender: UIButton) {

    // Load "mysoundname.wav"

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

        AudioServicesPlaySystemSound(mySound);
    }
}

Answer 19

Pour 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)
        }
    }
}

Answer 20

Ne pourriez-vous pas simplement import AVFoundation, sélectionner le lecteur audio (var audioPlayer : AVAudioPlayer!) et lire le son? (let soundURL = Bundle.main.url(forResource: "sound", withExtension: "wav")

Answer 21

Utilisez cette fonction pour produire du son dans Swift (vous pouvez utiliser cette fonction à l'endroit où vous souhaitez produire du son.)

Ajoutez d’abord SpriteKit et 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")

Answer 22

Swift 3, voici comment je le fais.

{

import UIKit
import AVFoundation

        let url = Bundle.main.url(forResource: "yoursoundname", withExtension: "wav")!
        do {

            player = try AVAudioPlayer(contentsOf: url); guard let player = player else { return }

            player.prepareToPlay()
            player.play()
        } catch let error as Error {
            print(error)

        }
    }

Answer 23

Ce code fonctionne pour moi:

class ViewController: UIViewController {

    var audioFilePathURL : NSURL!
    var soundSystemServicesId : SystemSoundID = 0

    override func viewDidLoad() {
        super.viewDidLoad()
        // 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.


    }


    @IBAction func PlayAlertSound(sender: UIButton) {

         AudioServicesPlayAlertSound(soundSystemServicesId)
    }
}
