I have a UISearchController embedded in my Navigation Bar and when i click it, the whole navigation bar goes off the screen until i press another area on the screen and then it comes back. Here is a link to the video. (video mightent have uploaded yet so give it some time, the link does work)
self.searchController = [[UISearchController alloc] initWithSearchResultsController:nil];
self.searchController.dimsBackgroundDuringPresentation = NO;
// Use the current view controller to update the search results.
self.searchController.searchResultsUpdater = self;
//Setting Style
self.searchController.searchBar.barStyle = UIBarStyleBlack;
self.searchController.searchBar.barTintColor = [UIColor colorWithRed:49.0/255.0 green:49.0/255.0 blue:61.0/255.0 alpha:1.0];
self.searchController.searchBar.backgroundImage = [UIImage imageNamed:#"BG"];
self.searchController.searchBar.placeholder = #"Search Artists, Songs, Albums etc.";
self.searchController.searchBar.keyboardAppearance = UIKeyboardAppearanceDark;
[self.searchController.searchBar sizeToFit];
self.definesPresentationContext = YES;
self.searchController.searchBar.tintColor = self.view.window.tintColor;
[self.searchController.searchBar setTintColor:[UIColor colorWithRed:(226.0/255.0) green:(56.0/255.0) blue:(83.0/255.0) alpha:(1.0)]];
self.searchController.searchBar.delegate = self;
self.navigationItem.titleView = self.searchController.searchBar;
}
- (void)updateSearchResultsForSearchController:(UISearchController *)searchController{
NSString *searchString = searchController.searchBar.text;
NSLog(#"You searched for %#", searchString);
[searchResultsTableView reloadData];
}
-(void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar{
[self.view addSubview:searchResultsTableView];
}
You need to add the following
self.searchController.hidesNavigationBarDuringPresentation = NO;
to stop UISearchController hiding the nav bar when activated (ref docs link).

Until iOS 11 was released, I had a search bar added to a UITableViewController. It is hidden under a navigation bar and is visible when user scrolls the table up. On iOS11, adjusting contentOffset or tableview.bound won't hide the search bar properly, sometimes it does work and sometimes it hides the first row, too. So, I've decided to move the search bar to the navigation bar. But, for some reason, I don't see it anywhere. Here's my code at viewDidLoad
YearTableViewController.m
- (void)viewDidLoad
{
[super viewDidLoad];
if (#available(iOS 11.0, *)) {
//iOS11 -> on navigation bar
self.searchController = [[UISearchController alloc] initWithSearchResultsController:nil];
self.searchController.searchResultsUpdater = self;
self.searchController.delegate = self;
self.searchController.searchBar.delegate = self;
self.searchController.searchBar.barStyle = UISearchBarStyleDefault;
self.searchController.searchBar.showsCancelButton = NO;
[self.searchController.searchBar sizeToFit];
self.searchController.hidesNavigationBarDuringPresentation = NO;
self.searchController.dimsBackgroundDuringPresentation = YES;
[self.navigationItem setSearchController:self.searchController];
[self.navigationController.navigationBar setPrefersLargeTitles:NO];
[self.navigationItem setLargeTitleDisplayMode:UINavigationItemLargeTitleDisplayModeNever];
self.definesPresentationContext = YES;
} else {
//iOS10 or previous -> on table view
UITableViewController *tableViewControllerForSearch = [[UITableViewController alloc]initWithStyle:UITableViewStylePlain];
tableViewControllerForSearch.tableView.dataSource = self;
tableViewControllerForSearch.tableView.delegate = self;
tableViewControllerForSearch.tableView.estimatedRowHeight = 40;
tableViewControllerForSearch.tableView.rowHeight = UITableViewAutomaticDimension;
self.searchController = [[UISearchController alloc] initWithSearchResultsController:tableViewControllerForSearch];
self.searchController.searchResultsUpdater = self;
self.searchController.delegate = self;
self.searchController.searchBar.frame = CGRectMake(self.searchController.searchBar.frame.origin.x, self.searchController.searchBar.frame.origin.y, self.searchController.searchBar.frame.size.width, 44.0);
self.tableView.tableHeaderView = self.searchController.searchBar;
self.definesPresentationContext = YES;
// No border between cells
tableViewControllerForSearch.tableView.separatorStyle = UITableViewCellSelectionStyleNone;
}
EDITED: 2017/10/20
As suggested, I've renamed and simplified the structure.
I have the following structure on storyboard.
UINavigationController: Initial view controller
YearPageViewController: Inside, it has YearTableViewController
On iOS10, it works fine. On iOS 11, I don't see the searchBar.
Thanks for your input.
What about adding
self.navigationItem.hidesSearchBarWhenScrolling = NO;
Obviously the search bar is hidden by default and only is to be seen when scrolling.
Hope will helpful to you On iOS11
if #available(iOS 11.0, *) {
self.navigationItem.hidesSearchBarWhenScrolling = NO;
}
I known why your view controller is stacks. set 'NO' flag in dimsBackgroundDuringPresentation
self.searchController.dimsBackgroundDuringPresentation = NO;
I am trying to embed a UISearchController's search bar in the titleView of my navigation controller's bar. Exactly this can be seen in the UICatalog sample code by Apple and works:
// Create the search results view controller and use it for the UISearchController.
AAPLSearchResultsViewController *searchResultsController = [self.storyboard instantiateViewControllerWithIdentifier:AAPLSearchResultsViewControllerStoryboardIdentifier];
// Create the search controller and make it perform the results updating.
self.searchController = [[UISearchController alloc] initWithSearchResultsController:searchResultsController];
self.searchController.searchResultsUpdater = searchResultsController;
self.searchController.hidesNavigationBarDuringPresentation = NO;
/*
Configure the search controller's search bar. For more information on how to configure
search bars, see the "Search Bar" group under "Search".
*/
self.searchController.searchBar.searchBarStyle = UISearchBarStyleMinimal;
self.searchController.searchBar.placeholder = NSLocalizedString(#"Search", nil);
// Include the search bar within the navigation bar.
self.navigationItem.titleView = self.searchController.searchBar;
self.definesPresentationContext = YES;
I try to do the same with this code:
self.searchSuggestionsController = [[SearchSuggestionsTableViewController alloc]initWithStyle:UITableViewStylePlain];
self.searchSuggestionsController.delegate = self;
self.searchController = [[UISearchController alloc]initWithSearchResultsController:self.searchSuggestionsController];
self.searchController.delegate = self;
self.searchController.searchResultsUpdater = self.searchSuggestionsController;
self.searchController.searchBar.delegate = self;
self.searchController.dimsBackgroundDuringPresentation = YES;
[self.searchController setHidesNavigationBarDuringPresentation:NO];
self.searchController.searchBar.searchBarStyle = UISearchBarStyleProminent;
[self.searchController.searchBar setPlaceholder:NSLocalizedString(#"Search", nil)];
[self.navigationItem setTitleView:self.searchController.searchBar];
if (self.searchQuery) {
[self.searchController.searchBar setText:_searchQuery.queryString];
}
self.definesPresentationContext = YES;
But when I run it on device or in simulator the search bar in the navigation bar will never become first responder. The keyboard is not showing up, I can't enter text. What I can do is use the clear button and the text clears but still I can't enter any texts.
Any ideas?
Old question, but just had a similar problem. Be sure to have embedded the "searchBar" in a valid navigation controller in the VC heirachy. That happened to be my mistake. So this works;
CCCTestVC *tVC = [[CCCTestVC alloc] init];
UINavigationController *nC = [[UINavigationController alloc] initWithRootViewController:tVC];
[self.navigationController presentViewController:nC animated:YES completion:nil];
as opposed to doing this;
CCCTestVC *tVC = [[CCCTestVC alloc] init];
[self.navigationController pushViewController:tVC animated:YES];
try implementing UISearchBarDelegate
and call searchBar' s becomeFirstResponder() in searchBarTextDidBeginEditing
then in searchBarTextDidEndEditing call resignFirstResponder()
i've been converting my searches from the old UISearchDisplayController to the new UISearchController. I've got it all working now but my last issue is with the results tableview that is shown.
The results tableview is displayed underneath the searchbar, and when you scroll down the tableview then goes through the status bar.
Attached are some images showing the issues, Does anyone have any suggestions as to why this is happening. I've included some of the set up code from my ViewDidLoad.
Search Tableview before searching
Search Tableview after searching & scrolling
if ([self respondsToSelector:#selector(edgesForExtendedLayout)])
self.edgesForExtendedLayout = UIRectEdgeNone;
self.extendedLayoutIncludesOpaqueBars=NO;
self.automaticallyAdjustsScrollViewInsets=NO;
[self.navigationController setNavigationBarHidden:NO animated:YES];
[super viewDidLoad];
self.extendedLayoutIncludesOpaqueBars = YES;
self.navigationController.navigationBar.translucent = NO;
[self setNeedsStatusBarAppearanceUpdate];
// create a filtered list that will contain products for the search results table.
self.filteredItems = [NSMutableArray arrayWithCapacity:[self.listContent count]];
// Initially display the full list. This variable will toggle between the full and the filtered lists.
self.displayedItems = self.listContent;
self.searchController = [[UISearchController alloc] initWithSearchResultsController:nil];
self.searchController.searchResultsUpdater = self;
self.searchController.searchBar.delegate = self;
self.searchController.dimsBackgroundDuringPresentation = NO;
[self.searchController.searchBar sizeToFit];
self.searchController.searchBar.placeholder = #"";
// Add the UISearchBar to the top header of the table view
self.TV.tableHeaderView = self.searchController.searchBar;
self.definesPresentationContext = YES;
UIView *theView = [[UIView alloc] initWithFrame:TV.frame];
[theView setBackgroundColor:[UIColor colorWithRed:0.090 green:0.388 blue:0.643 alpha:1]];
[TV setBackgroundView:theView];
[TV reloadData];
self.navigationItem.title = #"Search";

Thanks,

I ran into a problem where the UISearchController, when it animates the searchBar into the navigationBar, leaves the statusBar transparent and not the same color as the searchBar, like below:
I searched SO, and the below solution inspired by this question
- (void)willPresentSearchController:(UISearchController *)searchController {
self.navigationController.navigationBar.translucent = YES;
}
- (void)willDismissSearchController:(UISearchController *)searchController {
self.navigationController.navigationBar.translucent = NO;
}
fixes the problem for iOS9, but not for iOS8. I tried setting
self.extendedLayoutIncludesOpaqueBars = YES;
but with no effect. Also, setting
self.edgesForExtendedLayout = UIRectEdgeAll;
hides the initial searchBar under the navigationBar, so I cannot use it.
Here's my code for initiating a UISearchController under an opaque UINavigationBar:
UITableViewController *searchResultsController = [[UITableViewController alloc] initWithStyle:UITableViewStylePlain];
searchResultsController.tableView.dataSource = self;
searchResultsController.tableView.delegate = self;
self.searchController = [[UISearchController alloc] initWithSearchResultsController:searchResultsController];
self.searchController.delegate = self;
self.searchController.searchResultsUpdater = self;
self.searchController.searchBar.delegate = self;
self.searchController.searchBar.barTintColor = [UIColor whiteColor];
self.searchController.searchBar.frame = CGRectMake(0.0, 0.0, self.view.frame.size.width, 44.0); // Required for iOS8, not iOS9 though
[self.view addSubview:self.searchController.searchBar];
Any suggestions how to fix this for iOS8?
I set my searchBar in the navigationBar. When activated it animates and the cancel button appears. I'm trying to stop animation and prevent cancel button from appearing. My story board is a tableviewController set in a navigationController.
self.searchController = [[UISearchController alloc]initWithSearchResultsController:nil];
self.searchController.searchResultsUpdater = self;
self.searchController.dimsBackgroundDuringPresentation = NO;
self.searchController.hidesNavigationBarDuringPresentation = NO;
self.searchController.searchBar.frame = CGRectMake(self.searchController.searchBar.frame.origin.x, self.searchController.searchBar.frame.origin.y, self.searchController.searchBar.frame.size.width, 44.0);
self.navigationItem.titleView = self.searchController.searchBar;
[self.searchController.searchBar setShowsCancelButton:NO animated:NO];
Try [self.searchController.searchBar showsCancelButton:NO].
