ios - AvPlayer无法在设备中播放声音

我的代码在模拟器中可以正常运行，并且可以毫无问题地传输URL。但是，当插入实际设备时，它不会播放音频。我的代码如下

var playerItem: AVPlayerItem?
var player: AVPlayer?

func initPlayer() {
    let url:URL = URL(string:"https://storage.googleapis.com/purelightdatabucket/samples%2F60-Energy%20UPLIFT.mp3")!
    self.playerItem = AVPlayerItem(url: url)
    self.player=AVPlayer(playerItem: self.playerItem!)
    let playerLayer=AVPlayerLayer(player: self.player!)
    playerLayer.frame = CGRect(x: 0, y: 0, width: 10, height: 50) // actually this player layer is not visible
    self.view.layer.addSublayer(playerLayer)
}

最佳答案

将此代码放入 didFinishLaunchingWithOptions

 do {
       try AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playback)
       try AVAudioSession.sharedInstance().setActive(true)
 } catch {
     print(error)
 }
