AVAudioPlayer로 사운드 재생

AVAudioPlayer로 사운드 재생

---

사운드를 재생하려고하는데 AVAudioPlayer작동하지 않습니다.

편집 1 : 여전히 작동하지 않습니다.

편집 2 :이 코드는 작동합니다. 내 장치가 무음 모드였습니다.

import UIKit
import AVFoundation

class ViewController: UIViewController {

    var audioPlayer = AVAudioPlayer()

    override func viewDidLoad() {
        super.viewDidLoad()

        var alertSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("button-09", ofType: "wav"))
        println(alertSound)

        var error:NSError?
        audioPlayer = AVAudioPlayer(contentsOfURL: alertSound, error: &error)
        audioPlayer.prepareToPlay()
        audioPlayer.play()
    }
}

---

코드 수정 :

import UIKit
import AVFoundation

class ViewController: UIViewController {

    var audioPlayer = AVAudioPlayer()

    override func viewDidLoad() {
        super.viewDidLoad()

        var alertSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("button-09", ofType: "wav"))
        println(alertSound)

        // Removed deprecated use of AVAudioSessionDelegate protocol
        AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback, error: nil)
        AVAudioSession.sharedInstance().setActive(true, error: nil)

        var error:NSError?
        audioPlayer = AVAudioPlayer(contentsOfURL: alertSound, error: &error)
        audioPlayer.prepareToPlay()
        audioPlayer.play()
    }

}

Swift 3 및 Swift 4.1 :

import UIKit
import AVFoundation

class ViewController: UIViewController {
    private var audioPlayer: AVAudioPlayer?

    override func viewDidLoad() {
        super.viewDidLoad()

        let alertSound = URL(fileURLWithPath: Bundle.main.path(forResource: "button-09", ofType: "wav")!)
        print(alertSound)

        try! AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
        try! AVAudioSession.sharedInstance().setActive(true)

        try! audioPlayer = AVAudioPlayer(contentsOf: alertSound)
        audioPlayer!.prepareToPlay()
        audioPlayer!.play()
    }
}

---

Swift 2에 따라 코드는

var audioPlayer : AVAudioPlayer!

func playSound(soundName: String)
{
    let coinSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource(soundName, ofType: "m4a")!)
    do{
        audioPlayer = try AVAudioPlayer(contentsOfURL:coinSound)
        audioPlayer.prepareToPlay()//there is also an async version
        audioPlayer.play()
    }catch {
        print("Error getting the audio file")
    }
}

오디오 재생은 로컬 변수에 할당하기 때문에 viewDidLoad가 완료된 직후 할당 해제됩니다. 유지하려면 속성을 만들어야합니다.

---

해결 방법은 탐색 모음에 재생 / 일시 중지 / 중지 버튼이있는 AudioPlayer를위한 것입니다.

Swift 2.1에서는 아래 코드를 사용할 수 있습니다.

import UIKit
import AVFoundation

class ViewController: UIViewController {

    var player:AVAudioPlayer = AVAudioPlayer()

    override func viewDidLoad() {
            super.viewDidLoad()

            let audioPath = NSBundle.mainBundle().pathForResource("ARRehman", ofType: "mp3")
            var error:NSError? = nil
            do {
                player = try AVAudioPlayer(contentsOfURL: NSURL(fileURLWithPath: audioPath!))
            }
            catch {
                print("Something bad happened. Try catching specific errors to narrow things down")
            }

        }

    @IBAction func play(sender: UIBarButtonItem) {
        player.play()

    }


    @IBAction func stop(sender: UIBarButtonItem) {
        player.stop()
        print(player.currentTime)
        player.currentTime = 0
    }


    @IBAction func pause(sender: UIBarButtonItem) {

        player.pause()
    }


    @IBOutlet weak var sliderval: UISlider!


    @IBAction func slidermov(sender: UISlider) {

        player.volume = sliderval.value
        print(player.volume)
    }

}

작동합니다 .....

import UIKit
import AVFoundation

class ViewController: UIViewController {

    var ding:AVAudioPlayer = AVAudioPlayer()

    override func viewDidLoad() {
        super.viewDidLoad()

        prepareAudios()
        ding.play()
    }

    func prepareAudios() {

        var path = NSBundle.mainBundle().pathForResource("ding", ofType: "mp3")
        ding = AVAudioPlayer(contentsOfURL: NSURL(fileURLWithPath: path!), error: nil)
        ding.prepareToPlay()
    }
}

이 기능을 사용하여 Swift에서 소리를냅니다. (이 기능은 소리를 내고 싶은 곳에서 사용할 수 있습니다.)

먼저 SpriteKit 및 AVFoundation 프레임 워크를 추가합니다.

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")

이것은 꽤 오래된 질문이지만 Swift 3.0에서 작동하는 답변을 보지 못했기 때문에 코드를 현대화하고 충돌을 방지하기 위해 몇 가지 안전 검사를 추가했습니다.

나는 또한이 답변을 접하는 모든 사람이 재사용 할 수 있도록 재생 부분을 자체 기능으로 끌어내는 접근 방식을 취했습니다.

import UIKit
import AVFoundation

class ViewController: UIViewController {
    var audioPlayer: AVAudioPlayer?

    override func viewDidLoad() {
        super.viewDidLoad()

        play(for: "button-09", type: "wav")
    }

    func play(for resource: String, type: String) {
        // Prevent a crash in the event that the resource or type is invalid
        guard let path = Bundle.main.path(forResource: resource, ofType: type) else { return }
        // Convert path to URL for audio player
        let sound = URL(fileURLWithPath: path)
        do {
            audioPlayer = try AVAudioPlayer(contentsOf: sound)
            audioPlayer?.prepareToPlay()
            audioPlayer?.play()
        } catch {
            // Create an assertion crash in the event that the app fails to play the sound
            assert(false, error.localizedDescription)
        }
    }
}

Swift 4.2 이상에서는 AudioSession 카테고리 설정 옵션이 변경되었습니다. (Swift 4.2 이상에서 다음 코드를 시도하십시오)

import UIKit
import AVFoundation


class ViewController: UIViewController {


    var audioPlayer: AVAudioPlayer?

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


    func prepareAudioSession() -> Void {
        do {
            try AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playback, mode: AVAudioSession.Mode.default, options: AVAudioSession.CategoryOptions.defaultToSpeaker)
            try AVAudioSession.sharedInstance().setActive(true)

            prepareAudioPlayer()

        } catch {
            print("Issue with Audio Session")
        }
    }


    func prepareAudioPlayer() -> Void {

        let audioFileName = "test"
        let audioFileExtension = "mp3"

        guard let filePath = Bundle.main.path(forResource: audioFileName, ofType: audioFileExtension) else {
            print("Audio file not found at specified path")
            return
        }

        let alertSound = URL(fileURLWithPath: filePath)
        try? audioPlayer = AVAudioPlayer(contentsOf: alertSound)
        audioPlayer?.prepareToPlay()
    }


    func playAudioPlayer() -> Void {
        audioPlayer?.play()
    }


    func pauseAudioPlayer() -> Void {
        if audioPlayer?.isPlaying ?? false {
            audioPlayer?.pause()
        }
    }


    func stopAudioPlayer() -> Void {
        if audioPlayer?.isPlaying ?? false {
            audioPlayer?.stop()
        }
    }

    func resetAudioPlayer() -> Void {
        stopAudioPlayer()
        audioPlayer?.currentTime = 0
        playAudioPlayer()
    }

}
