How to deactivate playing a sound - swift

Question

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?
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.

Answer 1

Here's an example of how to use AVFoundation.
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):
#IBAction func MusicButton(sender: UIButton) {
if backgroundMusicPlayer.playing {
backgroundMusicPlayer.stop()
}
else {
playBackgroundMusic("SomeMusicName")
}
}
Stopping the music with AVFoundation is as easy as .stop() ^^!
