My iframe does not work with a UIWebView

问题

I have tested my iframe everywhere and it works very well, but on iOS in Objective-C, it does not work on UIWebView, here is my code, can someone help me? Thanks

self.webView.scrollView.scrollEnabled = NO;

NSString *Str = [NSString stringWithFormat:@"<iframe frameborder=\"0\" width=\"359\" height=\"200\" src=\"//www.dailymotion.com/embed/video/%@\" allowfullscreen></iframe>", identifier];

[_webView loadHTMLString:Str baseURL:nil];

My iframe :

<iframe frameborder="0" width="359" height="200" src="//www.dailymotion.com/embed/video/x5b4cfz" allowfullscreen></iframe>

You need to add this Key to your info.plist

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

The main problem that I found is the base Url, was missing in your code, so add this code with base url @"http://www.dailymotion.com", and changed the way to load html from loadHTMLString to loadData this always have better results for me

Edited: Improved your code to handle width of WebView as @Mozahler suggest was wrong

self.webView.scrollView.scrollEnabled = NO;

NSString *identifierTest = @"x5b4cfz";

NSString *Str = [NSString stringWithFormat:@"<iframe frameborder=\"0\" width=\"%@\" height=\"200\" src=\"//www.dailymotion.com/embed/video/%@\" allowfullscreen></iframe>",[NSString stringWithFormat:@"%f",self.webView.frame.size.width - 10], identifierTest];

NSLog([NSString stringWithFormat:@"%f",self.webView.frame.size.width - 10]);

[_webView loadData:[Str dataUsingEncoding:NSUTF8StringEncoding]
          MIMEType:@"text/html" textEncodingName:@"UTF-8"
           baseURL:[[NSURL alloc] initWithString:@"http://www.dailymotion.com"]];

it works, as you can see

Hope this helps
