ios – 无法通过AVPlayer通过HTTP播放mp3文件

我正在尝试通过AVPlayer播放MP3文件：

let url = URL(string: "http://transom.org/wp-content/uploads/2004/03/stereo_40kbps.mp3?_=7")!
let asset = AVURLAsset(url: url)
let item = AVPlayerItem(asset: asset)
let player = AVPlayer(playerItem: item)
player.play()

但是我得到了下一个日志：

2017-09-26 21:57:07.906598+0300 MyApp[7558:1177816] CredStore - performQuery - Error copying matching creds.  Error=-25300,query={
    class = inet;
    "m_Limit" = "m_LimitAll";
    "r_Attributes" = 1;
    sync = syna;
}

我想这是因为iOS 11和Xcode 9,但我不知道如何解决这个问题.

解决方法

问题似乎与App Transport安全性有关,启用后,它可以在iOS 11中使用以下几组代码正常工作,

您提供的上述URL似乎也有关联的https链接,请使用https链接或允许App Transport安全性

let avPlayerVC = AVPlayerViewController()
        let url = URL(string: "https://transom.org/wp-content/uploads/2004/03/stereo_40kbps.mp3?_=7")!
        let asset = AVURLAsset(url: url)
        let item = AVPlayerItem(asset: asset)
        let player = AVPlayer(playerItem: item)
        avPlayerVC.player = player

        present(avPlayerVC,animated: true) {
            player.play()
        }

但是在这里我使用了AVPlayerViewController,并使用了与代码中使用的AVPlayer相同的实例.我不知道你在如何使用AVPlayer,但上述情况很好.
