快速创作和播放声音-Java 学习之路

所以我想要做的就是在按下按钮时快速创建和播放声音，我知道如何在 Objective-C 中进行，但有没有人知道如何在 Swift 中？

对于 Objective-C 会是这样的：

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

然后玩它我会做：

AudioServicesPlaySystemSound(Explosion);

有谁知道我怎么做到这一点？

以下是我添加到 FlappySwift 中的一些代码：

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()
    }

}

这与其他一些答案类似，但也许更多“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);
}
```
请注意，这是重现问题中代码效果的一个简单示例。您需要确保import AudioToolbox，加上这种代码的一般模式是在应用启动时加载声音，将它们保存在某处的SystemSoundID实例变量中，在整个应用中使用它们，然后在您启动时调用AudioServicesDisposeSystemSoundID他们完成了他们。

Handy 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)
        }
    }
}

然后，从你的应用程序的任何地方(记得import AudioToolbox)，你可以打电话

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

玩“sound.mp3”

这会从名为Cha-Ching.aiff的文件中创建SystemSoundID。

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
}

使用 class＆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)
    }
}

用法：

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

这段代码适合我。使用 Try 和 Catch for AVAudioPlayer

    //Make sure that sound file is present in your Project.
    var CatSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("Meow-sounds.mp3", ofType: "mp3")!)

            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.

根据新的 Swift 2.0 我们应该使用 try 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()

使用此功能在 Swift 中发出声音(您可以在此处使用此功能 sound.)

首先添加 SpriteKit 和 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")

难道你不能只是import AVFoundation，选择音频播放器(var audioPlayer : AVAudioPlayer!)，然后播放声音？ (let soundURL = Bundle.main.url(forResource: "sound", withExtension: "wav")
