MyModalView has UISearchController embedded. The searchBar of U

Answer 1

I fixed it in my case by removing

definesPresentationContext = true

I didn't test yet if there are any disadvantages of removing this!

Answer 2

I had to

self.aNavigationController?.extendedLayoutIncludesOpaqueBars = true

I found a similar question here but in my case it was not on the viewDidLoad method. I had to try different views until it worked. Now I can have both a custom navigation bar color and the search bar,

Answer 3

I'm not sure what exactly is the problem but I 'fixed' it by:

self.searchController.hidesNavigationBarDuringPresentation = NO;
self.definesPresentationContext = NO;

My guess is that UISearchController is doing something funky when it is trying to present as a navigation bar. So, this is a hack but it at least doesn't block the user. The search bar doesn't do the cool animation and cover up the navigation bar.

Answer 4

I don't have a navigation bar in this place of an app. None of other SO posts helped me, so I've fixed it this way:

- (void)layoutSubviews
{
    [[[self searchController] searchBar] sizeToFit];
}

Answer 5

I found it's the simulated metrics (top bar) in storyboard that's cause this problem. In my case, the following lines work, but I still don't know why.

- (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 6

I had the same problem, and when I debugged the UI on Xcode I found that the UISearchBar view was moved to another view and the width was zeroed.

I fixed it by setting definesPresentationContext property of the UISearchController to false, and setting it true for the containing UITableViewController.

I added only one line to your viewDidLoad().

override func viewDidLoad() {
    super.viewDidLoad()

    // Dynamically create a search controller using anonymous function
    self.resultSearchController = ({
        let controller = UISearchController(searchResultsController: nil)
        controller.searchResultsUpdater = self
        controller.dimsBackgroundDuringPresentation = false
        controller.definesPresentationContext = false    // Disable the presentation controller

        controller.searchBar.sizeToFit()
        controller.searchBar.delegate = self

        self.tableView.tableHeaderView = controller.searchBar

        return controller
    })()

    // Auto sizing row & cell height
    self.tableView.estimatedRowHeight = 130
    self.tableView.rowHeight = UITableViewAutomaticDimension
    self.definesPresentationContext = true    // This one remains the same

    // No footer for better presentation
    self.tableView.tableFooterView = UIView.init(frame: CGRectZero)
