UISearchDisplayDelegate how to remove this opaque view?

Question

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

Answer 1

Code given by elpsk is current but will not work in iOS7 and above
Code working in both iOS6 and iOS7 is as below
- add below notification in viewDidLoad

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

Write below function

- (void) keyboardWillShow {
      for( UIView *subview in self.view.subviews ) {
       if([subview  isMemberOfClass:[UIControl class]] ||
         ([[[subview  class] description] isEqualToString:@"UISearchDisplayControllerContainerView"])) {
          UIControl *v = (UIControl*)subview;
          if (v.alpha < 1) {
            v.hidden = YES;
          }
        }
      }
    }

NOTE : Code just have one extra condition as in iOS7 UIControl class become UISearchDisplayControllerContainerView,
