我正试图播放声音,AVAudioPlayer但它无法正常工作.

编辑1:仍然无法正常工作.

编辑2:此代码有效.我的设备处于静音模式.

import UIKit
import AVFoundation

class ViewController: UIViewController {

    var audioPlayer = AVAudioPlayer()

    override func viewDidLoad() {
        super.viewDidLoad()

        var alertSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("button-09", ofType: "wav"))
        println(alertSound)

        var error:NSError?
        audioPlayer = AVAudioPlayer(contentsOfURL: alertSound, error: &error)
        audioPlayer.prepareToPlay()
        audioPlayer.play()
    }
}
