iOS - UIWebView loading HTML string contains iframe not working

I'm trying to load HTML String containing iframe to UIWebview the view takes the space of the content but it loads totally blank view here is the HTML

<html>
	<head>
		<meta http-equiv='Content-Type' content='charset=utf-8'/>
		<style>
			iframe{max-width:100% !important} 
		</style>
	</head>
	    <body>
	        <p dir="RTL"> <iframe allowfullscreen="" frameborder="0" height="573" id="molvideoplayer" scrolling="no" src="http://www.dailymail.co.uk/embed/video/1411595.html" title="MailOnline Embed Player" width="698"></iframe> </p> 
    </body> 
    </html>

aslo my code is

self.newsBodyWebView.loadHTMLString(htmlString, baseURL: nil)

Also I tried the UIWebView delegate function 

func webView(_ webView: UIWebView, didFailLoadWithError error: Error) {
    print(error.localizedDescription)
}

and I got this error

The operation couldn’t be completed. (NSURLErrorDomain error -999.)

I searched the error but nothing helped out.

When I removed the iframe and wrote any other html the UIWebView worked perfectly.

I don't know what's wrong with my code

EDIT

When I press any button to make changes in the container view the webview appears again, I am confused why this happens!

Solution

  • I finally figured it out, the web view height was set after webview finish launching this way 

    func webViewDidFinishLoad(_ webView: UIWebView) {
     webView.frame.size.height = 1
     self.webViewHeight = webView.sizeThatFits(CGSize.zero)
}

    I changed this to 

    func webViewDidFinishLoad(_ webView: UIWebView) {
     webView.frame.size.height = 1
     let height = webView.scrollView.contentSize.height
     var wvRect = webView.frame
     wvRect.size.height = height
     webView.frame = wvRect
}

    and every thing is working fine now.
