我使用webview加载url但是没有加载.

我尝试过与wkwebview相同但无法加载网址.

我做了以下

• 导入WebKit
• 的Info.plist
  • 允许任意负载 - 是
  • 允许在Web内容中任意加载 - 是

日志:

dnssd_clientstub ConnectToServer:connect() - >尝试次数:1

-码

 @IBOutlet weak var webvw: WebView!

 override func viewDidAppear() {
        super.viewDidAppear()

        guard let url = URL(string: "https://www.google.co.in") else { return }
        let request = URLRequest(url: url)

        webvw.uiDelegate = self
        webvw.frameLoadDelegate = self
        webvw.mainFrame.load(request)
    }

我正在开发音乐应用程序,但对于锁定屏幕控制,我无法分配持续时间和已用时间

这是我的代码

let commandCenter = MPRemoteCommandCenter.shared()

        commandCenter.previousTrackCommand.isEnabled = true;
        commandCenter.previousTrackCommand.addTarget(self, action:#selector(home_ViewController.btn_rewind(_:)))

        commandCenter.nextTrackCommand.isEnabled = true
        commandCenter.nextTrackCommand.addTarget(self, action:#selector(home_ViewController.btn_fast(_:)))

        commandCenter.playCommand.isEnabled = true
        commandCenter.playCommand.addTarget(self, action:#selector(home_ViewController.play_player))

        commandCenter.pauseCommand.isEnabled = true
        commandCenter.pauseCommand.addTarget(self, action:#selector(home_ViewController.pause_player))

        commandCenter.togglePlayPauseCommand.isEnabled = true
        commandCenter.togglePlayPauseCommand.addTarget(self, action:#selector(home_ViewController.togglePlay_Pause))

        commandCenter.skipBackwardCommand.isEnabled = false
        commandCenter.skipForwardCommand.isEnabled = false

        if #available(iOS 9.1, *) {
            commandCenter.changePlaybackPositionCommand.isEnabled = true
        } else {
            // Fallback on earlier versions
            return
        }

和媒体信息

func setLockInfo()
    {
        let url = URL(string: song_UrlString)
        let data = try? Data(contentsOf: url!)
        let art = MPMediaItemArtwork.init(image: UIImage(data: data!)!)



        let songInfo :[String : …
