Answer 1

Thanks @wiles duan and @Techprimate

In my case, I fixed this issue by setting:

self.definesPresentationContext = NO;

And implement the following 2 methods in UISearchControllerDelegate

- (void)willPresentSearchController:(UISearchController *)searchController {
    // do something before the search controller is presented
    self.navigationController.navigationBar.translucent = YES;
}

-(void)willDismissSearchController:(UISearchController *)searchController
{
    self.navigationController.navigationBar.translucent = NO;
}

Answer 2

It works

override func viewDidLoad() {
    super.viewDidLoad()

    self.extendedLayoutIncludesOpaqueBars = !self.navigationController!.navigationBar.translucent
}

Answer 3

sc.hidesNavigationBarDuringPresentation = false

does the trick for me

lazy var searchController:UISearchController = {
        let sc = UISearchController(searchResultsController: nil)
        sc.searchResultsUpdater = self
        sc.obscuresBackgroundDuringPresentation = false
        sc.searchBar.placeholder = "Search"
        sc.hidesNavigationBarDuringPresentation = false
        return sc
    }()

Answer 4

None of them worked for me, I fixed it using this hack

func position(for bar: UIBarPositioning) -> UIBarPosition {
    if UIDevice.current.userInterfaceIdiom == .pad {
        return .top
    } else {
        if iOSVersion <= 9 {
            return .top
        }
        return .topAttached
    }


}

It seems all of us got the same problem but they were solved in different ways. However none of the suggested answers worked for me :(. Nevertheless thank you all for your time.

I got a solution that solved my problem. It is setting Extend Edges - Under Opaque Bars of my (MyModalView: UITableViewController) to true in the Storyboard using Interface Builder.

In summary:

MyModalView: UITableViewController, in Storyboard using Interface Builder has

Extend Edges: - Under Top Bars ticked - Under Bottom Bars ticked - Under Opaque Bars ticked
