                                    }];

        [operation start];


}

any help appreciate..

Are you sure SampleText actually gets called? Because you used the HttpPost attribute above the actionresult. I'm not sure if this solves anything but when i do an ajax call to my actionresult i need to specify that the json is allowed to be called from get requests. return Json(txtName, JsonRequestBehavior.AllowGet);); — Jamie, Sep 30 '14 at 08:59

I don't know exactly how the parameters are being passed to your controller action (I'm not really familiar with objective-c) but the accepted answer might be worth exploring

How do I accept an array as an ASP.NET MVC controller action parameter?
