UISearchDisplayDelegate how to remove this opaque view?

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

Probably in searchDisplayControllerWillBeginSearch or searchDisplayControllerDidBeginSearch i开发者_JS百科 need to set something... but what?

thanks.

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.

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,

The other answers where not working for me. This one works for me on iOS7 and iOS8.

for( UIView *subview in self.view.subviews ) {
    if([subview  isMemberOfClass:[UIControl class]] ||
       ([[[subview  class] description] isEqualToString:@"UISearchDisplayControllerContainerView"])) {
        for(UIView *subView2 in subview.subviews)
        {
            for(UIView *subView3 in subView2.subviews)
            {
                if (subView3.alpha < 1) {
                    subView3.hidden = YES;
                }
            }
        }
    }
}

If you don't need support for iOS7 please don't use the searchDisplayController anymore because its deprecated. For iOS8 use the UISearchController and the dimsBackgroundDuringPresentation Property

Mmmm...quick answer. Not pretty but surely works

    #pragma mark UISearchBarDelegate

// Displays a view to simulate the lose of focus
- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar {

  searchBar.showsCancelButton = NO;
  searchBar.autocorrectionType = UITextAutocorrectionTypeNo;

  UIButton *view1 = [[UIButton alloc] init];
  view1.frame = CGRectMake(0, 0, 320, MAX(480, self.tableView.contentSize.height));
  view1.alpha = 0.6;
  view1.tag = 2000;
  view1.backgroundColor = [UIColor blackColor];
  [view1  addTarget:self
             action:@selector(removeView)
   forControlEvents:UIControlEventTouchUpInside];
  [self.tableView setScrollEnabled:NO];

  [self.tableView addSubview:view1];
  [view1 release];
}

/**
 *  Pop the view and the keyboard
 */
- (void)removeView {
  UIView *v = [self.tableView viewWithTag:2000];
  v.hidden = YES;
  [v removeFromSuperview];
  [self.tableView setScrollEnabled:YES];
  [self.searchBar resignFirstResponder];
}

That view is showed when you're writing, so I guess you should use it at searchBarTextDidBeginEditing. If I'm wrong, use it when you start searching or whatever.
