iOS 9 searchBar disappears from table header view when UISearchController is active

Question

The structure:

View1 (click a button) -> present modally (MyModalView: UITableViewController)

MyModalView has UISearchController embedded. The searchBar of UISearchController is placed in MyModalView.tableView.tableHeaderView.

It's been working fine since iOS 8.0. However on iOS 9, the searchBar disappear when the UISearchController is active. Please take a look at theses pictures below

The modal view:

UISearchController active on iOS 8:

UISearchController active on iOS 9:

The very standard code:

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.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

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

This issue also happens in iOS 9.1 beta...

Any idea / pointer would be deeply appreciated

Cheers.

Hi @IanDundas I posted my answer below would you want to try it to see if it'll fix your problem? — David Trang, Oct 11 '15 at 11:49
yes, actually @Shwethascar's fixes it lucky - thanks though. Just adding some context for others, that it only happens for me on the actual device. — Ian Dundas, Oct 12 '15 at 20:59
Try searchController.hidesNavigationBarDuringPresentation = false — Kevin, Dec 02 '16 at 09:14

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.

Yes, Only need searchController.hidesNavigationBarDuringPresentation = false, That's real solution. – Kevin Dec 02 '16 at 09:13
NO,not a real solution .Wht if we need to hide navigation bar and SearchBar is hidden under statusbar..? – Anees Dec 20 '16 at 13:28
I needed both these – devjme May 11 '17 at 20:05
This should be the accepted answer. This is the only thing that worked for me. Thanks. – the_critic Jun 13 '17 at 16:15
This is *still* the only answer I've found that fixes my problem. Agreed with above comments that the first part was sufficient. – cscott530 Jul 16 '20 at 20:21

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

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;
}

it happens even with pure code . I bet that translucent = false actually removes a view or something instead of disabling the translucent effect hence the search bar simply goes beyond the visible area – jigzat Oct 14 '15 at 01:40

don't forget to set the searchController delegate to the class implementing these methods (usually self) – lbarbosa Apr 12 '16 at 18:02
This was the solution that made it work for me! Thanks! – D6mi Aug 23 '16 at 11:23
`searchController.searchBar.searchBarStyle = .default` in `willPresent` and `.minimal` in `willDismiss` helped for me. – Nike Kov May 25 '17 at 09:23
Solved our issue as well - in our case the navigationBar overlaps the searchBar - setting translucent to on / off during inside the delegates fixed the issue. – hibento Aug 23 '17 at 15:32

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,

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;
}

I fixed mine by just implementing the delegate methods – jaytrixz Jul 21 '16 at 07:11 — jaytrixz, Jul 21 '16 at 07:11

I fixed it in my case by removing

definesPresentationContext = true

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

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)
}

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];
}

If you want to hide you navigation bar, and present search controller full screen, set the following on your navigation bar and search bar won't dissapper:

navigationController?.navigationBar.translucent = true

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

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
    }
