サウンドをすばやく作成して再生する

だから私がしたいことは、ボタンを押したときに再生されるサウンドを迅速に作成して再生することです、私はObjective-Cでそれを行う方法を知っていますが、誰もがSwiftで行う方法を知っていますか？

Objective-Cの場合は次のようになります。

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

そしてそれを再生するために私はやります：

AudioServicesPlaySystemSound(Explosion);

誰か私がこれを行う方法を知っていますか？

動作するFlappySwiftに追加したコードは次のとおりです。

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()
    }

}

これは他のいくつかの回答に似ていますが、おそらくもう少し「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);
}

これは問題のコードの効果を再現する簡単な例であることに注意してください。を確認する必要があります。import AudioToolboxさらに、この種のコードの一般的なパターンは、アプリの起動時にサウンドをロードし、SystemSoundIDインスタンス変数に保存して、アプリ全体で使用し、AudioServicesDisposeSystemSoundID終了時に呼び出すことです。彼らと。

Handy Swift拡張：

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)
        }
    }
}

次に、アプリのどこからでも（に覚えておいてくださいimport AudioToolbox）、

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

「sound.mp3」を再生する

これにより、SystemSoundIDというファイルからが作成されます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
}

クラスとAudioToolboxで：

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)
    }
}

使用法：

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()
    }
}

このコードは私にとってはうまくいきます。AVAudioPlayerのTry and Catchを使用する

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"はOSXのシステムサウンドですが、XCode内の "named"をクリックするだけで、この関数がサウンドを検索している場所を（QuickHelpペインで）表示できます。「サポートファイル」フォルダにあります

新しいSwift 2.0によると、do try catchを使用する必要があります。コードは次のようになります。

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()

これはSwift 4で動作しています：

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
        }
    }
}

この質問に対するより更新されたアプローチを見てみましょう：

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)
}

Matt Gibsonのソリューションがうまくいきました。Swift3バージョンです。

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

スウィフト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])
    }
}
}

または

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()

}
}

で働く 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);
 }

Swiftコード例：

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);
    }
}

あなたはSwift 5.2でこれを試すことができます：

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

Swift 4および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()    }

}

この関数を使用して、Swiftで音を出します（この関数は、音を出したい場所で使用できます）。

最初にSpriteKitとAVFoundation Frameworkを追加します。

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")

このコードは私にとってはうまくいきます：

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)
    }
}

用スウィフト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は私がそれを行う方法です。

{

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)

        }
    }

だけimport AVFoundationで、オーディオプレーヤー（var audioPlayer : AVAudioPlayer!）を選択して、サウンドを再生しませんか？（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] )
    }    

}
