如何停用播放声音

I have been trying to figure out how to deactivate playing a sound. I tried to attached a removeAtionWithKey with a sound action, and it seems to be working fine, but the sound does not stop to play. Is this because I am using action in SpriteKit?

我一直试图弄清楚如何停用播放声音。我尝试用声音动作附加一个removeAtionWithKey,它似乎工作正常,但声音不会停止播放。这是因为我在SpriteKit中使用动作吗?

If this problem is solved here instead of importing AVFoundation, then could you give me some examples to stop a sound from being played? Or, if importing AVFoundation is preferred in this case, could you provide me with some code as well.

如果这个问题在这里解决而不是导入AVFoundation,那么你能给我一些例子来阻止声音被播放吗?或者,如果在这种情况下首选导入AVFoundation,您是否也可以提供一些代码。

Here's an example of how to use AVFoundation.

这是一个如何使用AVFoundation的示例。

import Foundation
import AVFoundation

var backgroundMusicPlayer: AVAudioPlayer!

func playBackgroundMusic(filename: String) {

    let url = NSBundle.mainBundle().URLForResource(filename, withExtension: "mp3")

    if (url == nil) {
        print("Could not find the file \(filename)")
    }

    do { backgroundMusicPlayer = try AVAudioPlayer(contentsOfURL: url!, fileTypeHint: nil) } catch let error as NSError { print(error.debugDescription)}

    if backgroundMusicPlayer == nil {
        print("Could not create audio player")
    }

    backgroundMusicPlayer.numberOfLoops = -1
    backgroundMusicPlayer.prepareToPlay()
    backgroundMusicPlayer.play()
}

var Sound: AVAudioPlayer!

func playSound(filename: String) {

    let url = NSBundle.mainBundle().URLForResource(filename, withExtension: "wav")

    if (url == nil) {
        print("Could not find the file \(filename)")
    }

    do { Sound = try AVAudioPlayer(contentsOfURL: url!, fileTypeHint: nil) } catch let error as NSError { print(error.debugDescription)}

    if Sound == nil {
        print("Could not create audio player")
    }

    Sound.prepareToPlay()
    Sound.play()
}

And here's what you want to achieve (if I understood well):

这就是你想要实现的目标(如果我理解的话):

@IBAction func MusicButton(sender: UIButton) {
    if backgroundMusicPlayer.playing {
        backgroundMusicPlayer.stop()
    }
    else {
        playBackgroundMusic("SomeMusicName")
    }
}

Stopping the music with AVFoundation is as easy as .stop() ^^!

使用AVFoundation停止音乐就像.stop()^^一样简单!
