Question

这是我嵌入视频的方式。它在模拟器中有声音，但在真实设备上没有声音（iOS 9.0.2（13A452））Xcode 7.1.1。

这是我用来播放它的代码：

if let youtubeID = youtubeID {
    let embededHTML = "<html><body><iframe src=\"http://www.youtube.com/embed/\(youtubeID)?playsinline=1\" width=\"\(width)\" height=\"\(height)\" frameborder=\"0\" allowfullscreen></iframe></body></html>"
    cell!.webView.allowsInlineMediaPlayback = true
    cell!.webView.scalesPageToFit = true
    cell!.webView.mediaPlaybackAllowsAirPlay = true
    cell!.webView.mediaPlaybackRequiresUserAction = false

    cell!.webView.loadHTMLString(embededHTML, baseURL: NSBundle.mainBundle().bundleURL)
}

大多数开发人员遇到了他们忘记的这个问题 打开iPhone左侧的铃声按钮。它对我有用。

Answer 2

SWIFT 2.0版本我遇到了同样的问题，解决方案是在AppDelegate中添加

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {


    do {
        try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
    }
    catch let error as NSError {
        print(error)  
    }

    do {
        try AVAudioSession.sharedInstance().setActive(true)
    }
    catch let error as NSError {
        print(error)  
    }

    // Override point for customization after application launch.
    return true
}

这会在我的UIWebView中启用声音

我自己找到了答案：解决方案：

        if let youtubeID = youtubeID {
            let embededHTML = "<!DOCTYPE html><html><head><style type=\"text/css\"> body { margin: 0; padding: 0; } body, html { height: 100%; width: 100%; } </style> </head> <body> <iframe id=\"player\" type=\"text/html\" width=\"100%\" height=\"100%\" src=\"http://www.youtube.com/embed/\(youtubeID)?enablejsapi=1&playsinline=1\" frameborder=\"0\"></iframe> <script> var tag = document.createElement('script'); tag.src = \"https://www.youtube.com/iframe_api\"; var firstScriptTag = document.getElementsByTagName('script')[0]; firstScriptTag.parentNode.insertBefore(tag, firstScriptTag); var player; function onYouTubeIframeAPIReady() { player = new YT.Player('player', { events: { 'onReady': onPlayerReady } }); } function onPlayerReady(event) { event.target.playVideo(); } </script> </body></html>"

            cell!.webView.allowsInlineMediaPlayback = true
            cell!.webView.scalesPageToFit = true
            cell!.webView.mediaPlaybackAllowsAirPlay = true
            cell!.webView.mediaPlaybackRequiresUserAction = false
            cell!.webView.loadHTMLString(embededHTML, baseURL: NSBundle.mainBundle().bundleURL)
        }
