title: Return window in hitTest does not work
body: <p>I am trying to add custom UIWindow and forward the event to the mainWindow</p>
  
  <pre><code>-(UIView *) hitTest:(CGPoint)point withEvent:(UIEvent *)event{
  UIView *hitView = [super hitTest:point withEvent:event];
  if (hitView == self.myView) {
      return hitView;
  }else{
      return mainWindow;
  }}
  </code></pre>
  
  <p>It works when passing the View inside mainWindow.rootViewController.view
  but I want to pass it to the mainWindow</p>
