title: How to add a UIView over the Keyboard - iOS
body: <p>I have been trying to display a toast message on iOS. What I did was when any notification comes, just I took the navigation controller view and added a subview for my toast message and displayed. </p>
  
  <pre><code>    UIView *top_view = self.navigationController.view;
      [top_view showToast:string];
  </code></pre>
  
  <p>Everything works fine. However my toast view is not adding over the keyboard(if the keyboard is at the front). Any idea what could be the problem... Little helps may save my time... Thanx..</p>
