ios 快速创建和播放声音

Creating and playing a sound in swift

提问by Jacob Banks

So what I want to do is create and play a sound in swift that will play when I press a button, I know how to do it in Objective-C, but does anyone know how to in Swift?

所以我想要做的是在 swift 中创建和播放一个声音，当我按下按钮时会播放，我知道如何在 Objective-C 中做到这一点，但有没有人知道如何在 Swift 中做到这一点？

It would be like this for Objective-C:

对于Objective-C 来说是这样的：

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

And then to play it I would do:

然后玩它我会这样做：

AudioServicesPlaySystemSound(Explosion);

Does anyone know how I could do this?

有谁知道我怎么能做到这一点？

Here's a bit of code I've got added to FlappySwift that works:

这是我添加到 FlappySwift 的一些有效代码：

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()
    }

}

This is similar to some other answers, but perhaps a little more "Swifty":

这类似于其他一些答案，但可能更“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);
}

Note that this is a trivial example reproducing the effect of the code in the question. You'll need to make sure to import AudioToolbox, plus the general pattern for this kind of code would be to load your sounds when your app starts up, saving them in SystemSoundIDinstance variables somewhere, use them throughout your app, then call AudioServicesDisposeSystemSoundIDwhen you're finished with them.

请注意，这是一个简单的示例，可重现问题中代码的效果。你需要确保import AudioToolbox，加上这种代码的一般模式是在你的应用程序启动时加载你的声音，将它们保存在SystemSoundID某个地方的实例变量中，在你的应用程序中使用它们，然后AudioServicesDisposeSystemSoundID在你完成后调用跟他们。

Handy Swift extension:

方便的 Swift 扩展：

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)
        }
    }
}

Then, from anywhere in your app (remember to import AudioToolbox), you can call

然后，从您应用程序的任何位置（请记住import AudioToolbox），您可以调用

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

to play "sound.mp3"

播放“sound.mp3”

This creates a SystemSoundIDfrom a file called Cha-Ching.aiff.

这SystemSoundID将从名为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
}

With a class & AudioToolbox:

使用类和 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:

用法：

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

This code works for me. Use Try and Catch for AVAudioPlayer

这段代码对我有用。对 AVAudioPlayer 使用 Try and Catch

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()
    }
}

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()
    }
}

According to new Swift 2.0 we should use do try catch. The code would look like this:

根据新的 Swift 2.0，我们应该使用 do try catch。代码如下所示：

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()

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

"Morse.aiff" is a system sound of OSX, but if you just click on "named" within XCode, you'll be able to view (in the QuickHelp pane) where this function is searching the sounds. It can be in your "Supporting files" folder

“Morse.aiff”是 OSX 的系统声音，但如果您只在 XCode 中单击“named”，您将能够（在 QuickHelp 窗格中）查看此功能搜索声音的位置。它可以在您的“支持文件”文件夹中

this is working with Swift 4 :

这是与 Swift 4 一起使用的：

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