UISearchDisplayDelegate how to remove this opaque view?

Question

how can i programmatically show/hide this opaque view from UISearchDisplayController?

Answer 1

Temporary solved using UIKeyboardWillAppearNotification.

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow) name:UIKeyboardWillShowNotification object:nil];

OpaqueView is an UIControl with alpha = 0.8.

- (void) keyboardWillShow {
  for( UIView *subview in self.view.subviews ) {
   if( [subview isKindOfClass:[UIControl class]] ) {
      UIControl *v = (UIControl*)subview;
      if (v.alpha < 1) {
        v.hidden = YES;
      }
    }
  }
}

I used this ORRIBLE way to temporary fix problem.... any other idea will be appreciated!

thanks.
