How to hide UISearchController in UINavigationBar

Question

I have a navigation bar which is displayed without a search bar on it when the screen first displayed. I trigger and display the search bar in Navigation bar but I am wondering how to hide the search bar back and display Navigation bar title again.

I create the search bar as following:

_searchController = [[UISearchController alloc] initWithSearchResultsController:nil];

self.searchController.searchResultsUpdater = self;
self.searchController.searchBar.placeholder = nil;
[self.searchController.searchBar sizeToFit];
//self.tableView.tableHeaderView = self.searchController.searchBar;
self.sharedNavigationItem.titleView = _searchController.searchBar;

self.searchController.delegate = self;
self.searchController.dimsBackgroundDuringPresentation = NO; // default is YES
self.searchController.searchBar.delegate = self; // so we can monitor text changes + others
self.definesPresentationContext = YES;
_searchController.hidesNavigationBarDuringPresentation = NO;

I want to hide search bar only here and display a normal navigation bar with a title:

did u try changing self.sharedNavigationItem.titleView again? — Teja Nandamuri, Mar 09 '17 at 20:12

I had the same issue. Previous answers suggest to scrap the whole NavigationBar, but it is not the researched behaviour. The solution is to add the searchBar when the search button is pressed...

@IBAction func didPressAddButton(_ sender: Any) {
    if #available(iOS 11.0, *) {
        // For iOS 11 and later, place the search bar in the navigation bar.
        navigationItem.searchController = tagSearchController 
        navigationItem.hidesSearchBarWhenScrolling = true
    } else {
        // For iOS 10 and earlier, place the search controller's search bar in the table view's header.
        tableView.tableHeaderView = tagSearchController.searchBar
    }

    tagSearchController.isActive = true 
}

...and remove it when didDismissSearchController is called (UISearchControllerDelegate method).

func didDismissSearchController(_ searchController: UISearchController) {
    if #available(iOS 11.0, *) {
        // For iOS 11 and later, place the search bar in the navigation bar.
        navigationItem.searchController = nil

    } else {
        // For iOS 10 and earlier, place the search controller's search bar in the table view's header.
        tableView.tableHeaderView = nil
    }
}

NB: my searchController is created and configured in viewDidLoad()

You can try adding below the property.

hidesNavigationBarDuringPresentation.

For ref:

Another ref:

- (void)viewDidLayoutSubviews {
    [self.navigationController setNavigationBarHidden:NO animated:NO];
}

This hides entire navigation bar. I only want to hide search bar and display normal navigation bar. – birdcage Mar 10 '17 at 05:59

If you want to hide entire navigation bar and if you want to use your own navigation bar, you can first hide navigation controller's navigation bar.

[self.navigationController setNavigationBarHidden:YES];
//OR
[self.navigationController setNavigationBarHidden:YES animated:NO];

or if you have used custom title view for navigation bar, you can do

self.navigationItem.titleView.hidden = YES;

or if you want to hide back bar button item, you can do

self.navigationItem.hidesBackButton = TRUE;

or if you want to only hide title you can do

self.navigationItem.title = @"";

And

self.navigationController.navigationItem.titleView = nil ;

None, I want to hide only search bar and display normal navigation bar. – birdcage Mar 10 '17 at 05:58
In your code you added search bar in `titleView` then try to hide using `self.navigationItem.titleView.hidden = YES;` and then `self.navigationController.navigationItem.titleView = nil ;` – Sid Mhatre Mar 10 '17 at 06:04
it did not help. – birdcage Mar 10 '17 at 06:06
it hide search bar or not – Sid Mhatre Mar 10 '17 at 06:07
It did not effect anything. – birdcage Mar 10 '17 at 06:07
self.sharedNavigationItem.titleView.hidden = YES; and then self.sharedNavigationItem.navigationItem.titleView = nil ; solved it. Thanks. – birdcage Mar 10 '17 at 06:10
