I have a YouTube video embedded in a UIWebView. It plays just fine. When I segue to a different View Controller without pausing the video, however, it continues to play the audio. How do I stop it?

Code:

func loadYouTubeVideo() {

    let youTubeLink: String = "https://www.youtube.com/embed/ac_om5HCjvg"
    let width = 300
    let height = 200
    let frame = 50
    let html:NSString = "<iframe width=\(width) height=\(height) src=\(youTubeLink) frameborder=\(frame) allowfullscreen></iframe>"
    self.youTubeWebView.loadHTMLString(html as String, baseURL: nil)

}

I need a Swift answer. I've tried using Objective-C, but it doesn't translate unless I'm doing it wrong:

 let script = "var videos = document.querySelectorAll(\"video\"); for (var i = videos.length - 1; i >= 0; i--) { videos[i].pause(); };"
 youTubeWebView.stringByEvaluatingJavaScriptFromString(script)

  • Unfortunately, those answers don't work for me. It could be that it's in Objective-C, and I'm working in Swift. – swiftyboi Jan 20 '16 at 21:30
  • What do you mean they don't work? Have you tried translating them into Swift? – JAL Jan 20 '16 at 21:45

Try this

  override func viewWillDisappear(animated: Bool) {
        webView.loadHTMLString(nil, baseURL: nil)
    }

Let me know if it works

  • `loadHTMLString` requires a non-optional string HTML string, you can't pass in nil. – JAL Jan 21 '16 at 20:58

If you don't care about the user resuming the video from the beginning after navigating away from the view, have the webview load an empty page:

webView.loadHTMLString("<html><head></head><body></body></html>", baseURL: nil)

If you do this, you will have to load your video again in viewWillAppear.

I used the following to stop my audio: 

webView.loadHTMLString("", baseURL: nil)
