ios - wkwebview 不会在 iframe 中显示 youtube 视频

Question

我正在尝试在 iOS 9 下使用 WKWebView，其中一个页面恰好在 iframe 中包含 YouTube 视频。视频不显示。相同的视频可以在 Safari 中播放，因此似乎不是 iOS 问题，我认为我在 View 中缺少配置选项。示例 URL 为 http://www.w3schools.com/html/tryit.asp?filename=tryhtml_youtubeiframe .

import UIKit
import WebKit

class ViewController: UIViewController, WKNavigationDelegate
{
    var webView : WKWebView!

    override func viewDidLoad()
    {
        super.viewDidLoad()

        let webviewConfiguration                       = WKWebViewConfiguration()
        webviewConfiguration.allowsInlineMediaPlayback = true
        webviewConfiguration.preferences.javaScriptCanOpenWindowsAutomatically = true
        webviewConfiguration.allowsAirPlayForMediaPlayback       = true
        webviewConfiguration.allowsPictureInPictureMediaPlayback = true
        webviewConfiguration.requiresUserActionForMediaPlayback  = false
        webView                    = WKWebView(frame: self.view.bounds,
            configuration: webviewConfiguration)
        webView.navigationDelegate = self
        self.view                  = webView
        let url = NSURL(string: "http://www.w3schools.com/html/tryit.asp?filename=tryhtml_youtubeiframe")
        let req = NSURLRequest(URL: url!)
        self.webView!.loadRequest(req)
    }

    override func didReceiveMemoryWarning()
    {
        super.didReceiveMemoryWarning()
    }

    func webView(webView: WKWebView,
        didFailNavigation navigation: WKNavigation!,
        withError error: NSError)
    {
        print("didFailNavigation \(error)")
    }

    func webView(webView: WKWebView,
        didFailProvisionalNavigation navigation: WKNavigation!,
        withError error: NSError)
    {
        print("didFailProvisionalNavigation  \(error)")
    }
}

转到项目 info.plist 文件 添加了一个名为 NSAppTransportSecurity 的键作为字典。 添加了一个名为 NSAllowsArbitraryLoads 的子键作为 bool 值并将其值设置为 YES。有用。
