Szybkie tworzenie i odtwarzanie dźwięku

Chcę więc stworzyć i odtworzyć dźwięk w języku Swift, który będzie odtwarzany po naciśnięciu przycisku. Wiem, jak to zrobić w Objective-C, ale czy ktoś wie, jak to zrobić w Swift?

Tak wyglądałoby w przypadku Objective-C:

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

A potem, żeby to zagrać, zrobiłbym:

AudioServicesPlaySystemSound(Explosion);

Czy ktoś wie, jak mogłem to zrobić?

Oto fragment kodu, który dodałem do FlappySwift, który działa:

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()
    }

}

Jest to podobne do innych odpowiedzi, ale być może trochę bardziej „szybkie”:

// 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);
}

Zauważ, że jest to trywialny przykład odtwarzający efekt kodu w pytaniu. Musisz się upewnić import AudioToolbox, a ogólny wzorzec dla tego rodzaju kodu polegałby na ładowaniu dźwięków podczas uruchamiania aplikacji, zapisywaniu ich SystemSoundIDgdzieś w zmiennych instancji, używaniu ich w całej aplikacji, a następnie wywołaniu, AudioServicesDisposeSystemSoundIDgdy skończysz z nimi.

Poręczne rozszerzenie 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)
        }
    }
}

Następnie import AudioToolboxmożesz dzwonić z dowolnego miejsca w aplikacji (pamiętaj o tym )

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

aby odtworzyć „sound.mp3”

Tworzy to SystemSoundIDz pliku o nazwie 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
}

Z klasą i 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)
    }
}

Stosowanie:

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

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()
    }
}

Ten kod działa dla mnie. Użyj Try and Catch dla 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()

„Morse.aiff” to dźwięk systemowy OSX, ale jeśli po prostu klikniesz „named” w XCode, będziesz mógł zobaczyć (w panelu QuickHelp), gdzie ta funkcja wyszukuje dźwięki. Może znajdować się w folderze „Pliki pomocnicze”

Zgodnie z nowym Swiftem 2.0 powinniśmy używać do try catch. Kod wyglądałby tak:

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()

to działa ze Swift 4:

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

//Swift 4
import UIKit
import AVFoundation

class ViewController: UIViewController {

    var player : AVAudioPlayer?

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

    @IBAction func notePressed(_ sender: UIButton) {
        let path = Bundle.main.path(forResource: "note1", ofType: "wav")!
        let url = URL(fileURLWithPath: path)
        do {
            player = try AVAudioPlayer(contentsOf: url)
            player?.play()
        } catch {
            // error message
        }
    }
}

Zobaczmy bardziej aktualne podejście do tego pytania:

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)
}

Rozwiązanie Matta Gibsona zadziałało dla mnie, oto wersja Swift 3.

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

Szybki 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:
        AudioServicesPlaySystemSound(sounds[5])
    default:
        AudioServicesPlaySystemSound(sounds[6])
    }
}
}

lub

import UIKit
import AVFoundation

class ViewController: UIViewController, AVAudioPlayerDelegate{

var audioPlayer : AVAudioPlayer!

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

@IBAction func notePressed(_ sender: UIButton) {

    let soundURL = Bundle.main.url(forResource: "note\(sender.tag)", withExtension: "wav")

    do {
        audioPlayer = try AVAudioPlayer(contentsOf: soundURL!)
    }
    catch {
        print(error)
    }

    audioPlayer.play()

}
}

pracuje w 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);
 }

Przykład szybkiego kodu :

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);
    }
}

Możesz spróbować tego w 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()
    }

swift 4 i 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")

    if Bundle.main.path(forResource: "note1", ofType: "wav") != nil {
        print("Continue processing")
    } else {
        print("Error: No file with specified name exists")
    }

    do {
        if let fileURL = Bundle.main.path(forResource: "note1", ofType: "wav") {
            audioPlayer = try AVAudioPlayer(contentsOf: URL(fileURLWithPath: fileURL))
        } else {
            print("No file with specified name exists")
        }
    } catch let error {
        print("Can't play the audio file failed with an error \(error.localizedDescription)")
    }


    audioPlayer?.play()    }

}

Użyj tej funkcji, aby uzyskać dźwięk w języku Swift (możesz użyć tej funkcji, jeśli chcesz uzyskać dźwięk).

Najpierw dodaj SpriteKit i 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")

Ten kod działa dla mnie:

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)
    }
}

Dla 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)
        }
    }
}

Swift 3 Oto jak to zrobić.

{

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)

        }
    }

Nie mógłbyś po prostu import AVFoundationwybrać odtwarzacza audio ( var audioPlayer : AVAudioPlayer!) i odtworzyć dźwięk? ( let soundURL = Bundle.main.url(forResource: "sound", withExtension: "wav")

import UIKit
import AudioToolbox

class ViewController: UIViewController {

    let toneSound : Array =  ["note1","note2","note3","note4","note5","note6"]

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.

    }

    func playSound(theTone : String) {
        if let soundURL = Bundle.main.url(forResource: theTone, withExtension: "wav") {
            var mySound: SystemSoundID = 0
            do {
                AudioServicesCreateSystemSoundID(soundURL as CFURL, &mySound)
                // Play
                AudioServicesPlaySystemSound(mySound);
            }
            catch {
               print(error)
            }
        }
    }

    @IBAction func anypressed(_ sender: UIButton) {
        playSound(theTone: toneSound[sender.tag-1] )
    }    

}
