如何快速停止音频播放器

Question

So in my app the user plays an instrumental when they hit the play button but when they stop it should stop the music. In my code when i add the code for the stop button nothing plays when i hit the play button but when i delete the code the play button works but the stop button doesn't. I don't see why its doing that in my code.

Here is code:

@IBAction func playInstrumentalPressed(sender: AnyObject) {
    let documentsPath = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as String
    let saveFileName = nameSavedFile as String
    if (saveFileName != "") {
        let beatLocation = documentsPath + "/" + saveFileName + ".wav"
        let fileURL = NSURL(fileURLWithPath: beatLocation)

        var error:NSError?

        player = AVAudioPlayer(contentsOfURL: fileURL, error: &error)

        if player.prepareToPlay() && player.play() {
            println("yes")
        } else {
            println("no")
        }

    } else {
        println("Not Available") //add alertview here
    }
}

@IBAction func stopInstrumentalButton(sender: UIButton) {
    if (player.playing) {
        player.stop()
    } else {
        println("Nothing is playing")
    }
      }

我想知道您的iBAction插座是否连接不正确...也许仔细检查您的xib / storyboard xib以查看按钮的连接方式
