1. The use of UIView.
   How to load local HTML:
   

   var context = (Jscontext) Webview.valueforkeypath ((nsstring) "DocumentView.webView.mainFrame.javaScriptContext");            Context. Exceptionhandler = (Jscontext context2, jsvalue exception) =            {                Console.WriteLine ("JS exception: {0}", exception);            };            You can use JS to invoke C # code, like Android, by invoking the C # method by using the Mycsharpobject object            var myexporter = new Myjsexporter ();            context[(nsstring) "mycsharpobject"] = Jsvalue.from (myexporter, context);            var nsurl = new Nsurl ("demotest.html", false);            var nsrequest = Nsurlrequest.fromurl (nsurl);            Nsurl URL = NSBundle.MainBundle.GetUrlForResource ("main", "HTML");            String htmlstring = Nsstring.fromdata (Nsdata.fromurl (URL), Nsstringencoding.utf8);            Webview.loadhtmlstring (htmlstring, NSBUNDLE.MAINBUNDLE.BUNDLEURL);

   declaring interfaces

   <summary>        ///JS calling the C # code method interface        ///</summary> [Protocol ()]        interface Imyjsvisibleprotocol:ijsexport        {            [Export ("MyFunc")]            int myFunc ();            [Export ("Arity2:with:")]            NSObject Arity2with (nsobject arg1, NSObject arg2);        }

   Implementation method

   <summary>///Method realization///        </summary>        class Myjsexporter:nsobject, imyjsvisibleprotocol< c13/>{public            int MyFunc ()            {                Console.WriteLine ("called!");                return;            }            Public NSObject Arity2with (nsobject arg1, nsobject arg2)            {                Console.WriteLine ("Arity 2 function called with" + A Rg1 + "" + arg2);                return (NSNumber);}         }

   JS Call

   <script type= "Text/javascript" >        function Callxamobject () {            //' mycsharpobject ' injected into JS context By C # code ' context [(nsstring) "mycsharpobject"] = Jsvalue.from (... etc ... '            alert ("123");            var resultcalculatedincsharp = Mycsharpobject.myfunc ();            document.getElementById ("Output"). InnerHTML = Resultcalculatedincsharp;        }        function Callarity2method () {//note How this is            mapped by [Export ("Arity2:with:")]            var result = Mycsharpobject.a Rity2with ("foo", "Bar");        }    </script>
