Stop video in UIWebView

Also you can try to pause video:

NSString *script = @"var videos = document.querySelectorAll(\"video\"); for (var i = videos.length - 1; i >= 0; i--) { videos[i].pause(); };";
[webView stringByEvaluatingJavaScriptFromString:script];

Do integrate following code to sort out the problem.

    -(void)viewWillDisappear:(BOOL)animated
    {
        [webView loadHTMLString:nil baseURL:nil];
    }
