试图用斯威夫特AVPlayer播放音频 [英] Trying to play audio with Swift AVPlayer

问题描述

下面是我当前的ViewController：

Here's my current ViewController:

import UIKit
import AVFoundation

class SecondViewController: UIViewController {
    override func viewDidLoad() {
        var player = AVPlayer()
            let url = "http://www.nasa.gov/mp3/640149main_Computers%20are%20in%20Control.mp3"
            let playerItem = AVPlayerItem( URL:NSURL( string:url ) )
            player = AVPlayer(playerItem:playerItem)
            player.rate = 1.0;
            player.play()
    }
}

当我在模拟器上我没有得到任何音频运行它，它可能是iOS的SIM卡不播放音频或问题，我的code？

When I run this in the simulator I get no audio, could it be that the iOS sim doesn't play audio, or an issue with my code?

推荐答案

招行

    var player = AVPlayer()

...所以它的前的行：

override func viewDidLoad() {
