Scope buttons hiding behind the UITableview

Question

I am creating a search screen using UISearchController, in which I have to show three scope buttons.I have put search bar programmatically.But somehow the scope buttons are hiding behind the UITableView.

- (void)viewDidLoad {
    [super viewDidLoad];
    self.searchController = [[UISearchController alloc] initWithSearchResultsController:nil];
    self.searchController.searchResultsUpdater = self;
    self.searchController.dimsBackgroundDuringPresentation = NO;
    self.searchController.searchBar.delegate = self;
    self.tblFoundList.tableHeaderView = self.searchController.searchBar;
    self.definesPresentationContext = YES;
    [[UITextField appearanceWhenContainedInInstancesOfClasses:@[[UISearchBar class]]] setDefaultTextAttributes:@{NSForegroundColorAttributeName: [UIColor blackColor]}];
    [[UITextField appearanceWhenContainedInInstancesOfClasses:@[[UISearchBar class]]] setAttributedPlaceholder:[[NSAttributedString alloc] initWithString:@"Search by" attributes:@{NSForegroundColorAttributeName: [UIColor lightGrayColor]}]];
    self.searchController.searchBar.tintColor = [UIColor purpleColor];
    self.searchController.searchBar.barTintColor = [UIColor groupTableViewBackgroundColor];
    self.searchController.searchBar.scopeButtonTitles = @[@"A",@"B", @"C"];
    [self.searchController.searchBar sizeToFit];
}

Could anyone help in this? Thank you.

Answer 1

As I mentioned earlier I had created UISearchController programmatically, so the UITableview in the image is UISearchController's UITableview, that is why nothing was affecting it.

So I got help from

UISearchController Search Bar Position Drops 64 points

and

UISearchBar presented by UISearchController in table header view animates too far when active

- (UIBarPosition)positionForBar:(id<UIBarPositioning>)bar
    {
      if (bar == self.searchController.searchBar) {
        return UIBarPositionTopAttached;
      }
      else { // Handle other cases
        return UIBarPositionAny;
      }
    }

On adding following method the search bar got shifted up and the scope buttons were visible.

But thank you all for helping out.
