title: Present ViewController over current context but the presenting View controller should take control of user interraction
body: <p>I am presenting a bottom banner over the current context:</p>
  
  <pre><code>        self.bottomViewController.modalPresentationStyle = .overCurrentContext
          self.present(self.bottomViewController, animated: true, completion:{
              self.addChildViewController(self.bottomViewController)
              self.bottomViewController.didMove(toParentViewController: self)
          })
  </code></pre>
  
  <p>After presenting the modal view controller, I want the parent to still receive the touch events and takes control.</p>
  
  <p>For some reasons I can't use the containment (add the view as subview and then animate the presentation)</p>
