 进口的UIKit
进口AVFoundation类VesuviusViewController：UIViewController的{    @IBOutlet弱VAR PausePlay：UIButton的！    FUNC playVes（）{
        做{        _ =尝试AVAudioPlayer（contentsOfURL：NSURL（fileURLWithPath：NSBundle.mainBundle（）pathForResource（新村，ofType：M4A））！）        } {抓
            打印（错误）
        }
    }    @IBAction FUNC为playButton pressed（发件人：AnyObject）{
        playVes（）
    }    覆盖FUNC viewDidLoad中（）{
        super.viewDidLoad（）        //在载入视图后的任何额外的设置。    }    覆盖FUNC didReceiveMemoryWarning（）{
        super.didReceiveMemoryWarning（）
        可以重新创建任何资源的处置//。    }
}
 

更新的
正确的code：

 进口的UIKit
进口AVFoundation类VesuviusViewController：UIViewController的{
@IBOutlet弱VAR PausePlay：UIButton的！@IBAction FUNC玩pressed（发件人：AnyObject）{
    VesSet（）
}
VAR audioPlayer：AVAudioPlayer！    FUNC VesSet（）{
        做{
            self.audioPlayer =尝试AVAudioPlayer（contentsOfURL：NSURL（fileURLWithPath：NSBundle.mainBundle（）pathForResource（新村，ofType：M4A））！）
            self.audioPlayer.play（）        } {抓
            打印（错误）
        }
    }
    覆盖FUNC viewDidLoad中（）{
        super.viewDidLoad（）        //在载入视图后的任何额外的设置。    }    覆盖FUNC didReceiveMemoryWarning（）{
        super.didReceiveMemoryWarning（）
        可以重新创建任何资源的处置//。    }
}
 

解决方案

试试这个：

  VAR audioPlayer：AVAudioPlayer！ //全局变量
 

和播放方法：

  FUNC playVes（）{
        做{
            self.audioPlayer =尝试AVAudioPlayer（contentsOfURL：NSURL（fileURLWithPath：NSBundle.mainBundle（）pathForResource（新村，ofType：M4A））！）
            self.audioPlayer.play（）        } {抓
            打印（错误）
        }
    }
 

希望这有助于！

I am currently on Xcode 7 beta 4 with Swift 2, trying to play audio. I do not get any error in my code, but when I press the play button, the audio does not play. I cant figure out what is wrong.

import UIKit
import AVFoundation

class VesuviusViewController: UIViewController {

    @IBOutlet weak var PausePlay: UIButton!

    func playVes() {
        do {

        _ = try AVAudioPlayer(contentsOfURL: NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("Ves", ofType: "m4a")!))

        } catch {
            print("Error")
        }
    }

    @IBAction func playButtonPressed(sender: AnyObject) {
        playVes()
    }

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.

    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.

    }
}

UPDATE Correct code:

import UIKit
import AVFoundation

class VesuviusViewController: UIViewController {


@IBOutlet weak var PausePlay: UIButton!



@IBAction func playPressed(sender: AnyObject) {
    VesSet()
}
var audioPlayer: AVAudioPlayer!

    func VesSet(){


        do {
            self.audioPlayer =  try AVAudioPlayer(contentsOfURL: NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("Ves", ofType: "m4a")!))
            self.audioPlayer.play()

        } catch {
            print("Error")
        }


    }
    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.

    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.

    }
}

解决方案

Try this:

var audioPlayer: AVAudioPlayer! // Global variable

And play method:

func playVes() {
        do {
            self.audioPlayer =  try AVAudioPlayer(contentsOfURL: NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("Ves", ofType: "m4a")!))
            self.audioPlayer.play()

        } catch {
            print("Error")
        }
    }

Hope this helps!
