Scope buttons hiding behind the UITableview - ios

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.
