UISearchDisplayController with displaysSearchBarInNavigationBar pushes result view down with navigationBar.translucent = false

Just enabled "Under Opaque Bars " in the storyboard for your view controller or if you like to code.Then add the below lines.Your good :)

self.edgesForExtendedLayout = UIRectEdgeAll;self.extendedLayoutIncludesOpaqueBars = YES;

I had the same issue and I've fixed in this way:

1. Subclass UISearchDisplayController to have the UISearchBar in the NavigationBar for iOS 6 and 7. I've overwrite:

    -(void)setActive:(BOOL)visible animated:(BOOL)animated    {        if (SYSTEM_VERSION_LESS_THAN(@"7")) {            if(self.active == visible) return;            [self.searchContentsController.navigationController setNavigationBarHidden:NO animated:NO];            if (visible) {                [self.searchBar becomeFirstResponder];            } else {                [self.searchBar resignFirstResponder];            }        } else {            self.searchContentsController.view.frame = CGRectMake(0, 0, kCurrentScreenWidth, kCurrentScreenHeight);            [super setActive:visible animated:animated];        }    }

2.In the UISearchDisplayDelegate I've added this:

    - (void) searchDisplayController:(UISearchDisplayController *)controller didShowSearchResultsTableView:(UITableView *)tableView {        // iOS7 Hack        if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7")) {            controller.searchResultsTableView.contentInset = UIEdgeInsetsMake(0.f, 0.f, 0.f, 0.f);        }    }    - (BOOL) searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString    {        // -- iOS 7 Hack        if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7")) {            controller.searchResultsTableView.frame = CGRectMake(0, 64, kCurrentScreenWidth, kCurrentScreenHeight-64);            [controller.searchContentsController.view setNeedsLayout];        }    }

I had the same issue and after hours of searching for an answer, I decided to look through the view hierarchy. It seems that the superview of the searchBar, which is also the dimmed view, has a y origin of 64 and a height of 504, which is not populating the whole screen. Not sure why it's like that. Nevertheless, I ended up setting the y to 0 and it's height to the screen height. After which, I set its y back to the original value, or else your content table view will be distorted. It's not the best solution, but it's better than nothing. Hope this helps you.

- (void)searchDisplayControllerWillEndSearch:(UISearchDisplayController *)controller {    self.savedSearchTerm = nil;    UIView *dimmedView = controller.searchBar.superview;    CGRect frame = dimmedView.frame;    frame.origin.y = 64;    dimmedView.frame = frame;    [self.tableView reloadData];}- (void)searchDisplayControllerWillBeginSearch:(UISearchDisplayController *)controller {    UIView *dimmedView = controller.searchBar.superview;    CGRect frame = dimmedView.frame;    frame.origin.y = 0;    frame.size.height = 568;    dimmedView.frame = frame;}
