该视频无法播放，错误代码：152-4

移动开发 2026-07-12

在我的应用中以嵌入方式显示YouTube视频时，它显示错误代码：152 - 4。
我只是想做一个视图，通过传入YouTube ID就能在应用内的特定屏幕/视图中播放该视频。现在在尝试播放时就会出现这个错误。

有没有解决方法？到现在还没找到。

我的代码：

final class YouTubePlayerViewController: UIViewController, WKNavigationDelegate {

    var youtubeId: String
    private var webView: WKWebView!

    init(youtubeId: String) {
        self.youtubeId = youtubeId
        super.init(nibName: nil, bundle: nil)
    }

    required init?(coder: NSCoder) { fatalError() }

    override func viewDidLoad() {
        super.viewDidLoad()
        view.backgroundColor = .black
        setupWebView()
        loadPlayer()
    }

    private func setupWebView() {
        let config = WKWebViewConfiguration()
        config.allowsInlineMediaPlayback = true
        config.allowsAirPlayForMediaPlayback = true
        config.allowsPictureInPictureMediaPlayback = true
        config.mediaTypesRequiringUserActionForPlayback = []

        // Required — tells WKWebView it is allowed to autoplay / inline play
        let prefs = WKWebpagePreferences()
        prefs.allowsContentJavaScript = true
        config.defaultWebpagePreferences = prefs

        webView = WKWebView(frame: view.bounds, configuration: config)
        webView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
        webView.navigationDelegate = self
        webView.scrollView.isScrollEnabled = false
        webView.scrollView.bounces = false
        webView.backgroundColor = .black
        webView.isOpaque = true
        view.addSubview(webView)
    }

    func loadPlayer() {
        // The critical trick: we load a real youtube.com URL as the *base*
        // and inject an autoplay embed via HTML. Because the base URL is
        // genuinely youtube.com, WKWebView passes YouTube's origin check.
        let html = """
