I have added a UISearchController to my code using the following method:
self.searchController = [[UISearchController alloc] initWithSearchResultsController:nil];
self.searchController.searchResultsUpdater = self;
self.searchController.dimsBackgroundDuringPresentation = NO;
self.searchController.searchBar.scopeButtonTitles = #[];
self.searchController.searchBar.delegate = self;
self.tableView.tableHeaderView = self.searchController.searchBar;
[self.searchController.searchBar sizeToFit];
self.definesPresentationContext = YES;
This creates my search controller and adds it to the top of my tableView. Annoyingly it starts visible though:
I can hide it by sliding it up under the navigation bar which suggests the underlying functionality of the code is working but I can't get it to start hidden so I can slide it down.
I have tried adjusting the edge insets, I have tried setting the navigation bar to translucent, I have tried to go through the search bar tutorials online but nothing seems to be dealing with this issue.
Any help very welcome
Did you try setting the content offset of your table view?
[self.tableView setContentOffset:CGPointMake(0, self.searchController.searchBar.frame.size.height) animated:NO];
Here is for swift 4
tableView.setContentOffset(CGPoint(x: 0, y: searchController.searchBar.frame.size.height), animated: true)
From iOS 11.0 onwards you can use,
self.navigationItem.searchController = self.searchController;
The search bar will be hidden, unless you swipe down to reveal it.

I have a search bar as a title view for my navigation bar.
And it looks like this, the way I want it to look like:
But when I tap on it, it just slides to top and becomes inaccessible
Here is the code I used to configure it:
- (void)configureSearchBar
{
self.searchController = [[UISearchController alloc] initWithSearchResultsController:nil];
self.searchController.searchBar.delegate = self;
self.navigationItem.titleView = self.searchController.searchBar;
}
Is there any way to fix this kind of problem?
self.searchController.hidesNavigationBarDuringPresentation = NO
Adding this line has solved this problem or me. The reason of this problem was that my search bar was set as a title view for my navigation bar and the property hidesNavigationBarDuringPresentation was set to YES by default. Setting this property to NO solves this kind of problem.
I have page controller in which I added two tableviews. In each header of tableview search controller added, also viewForHeader method return "Recent" and "Other" view's.
My problem is the search bar does not appear when the search bar clicked.
It appear to move up, I cant see what I am typing there.
There may be the possibility that the search bar is hidden behind "Connection","Message" tab.
How to keep search bar at same position when keyboard become first responder?
any help will appreciated.
Have u used below lines of code at ViewDidLoad
if ([self respondsToSelector:#selector(edgesForExtendedLayout)])
self.edgesForExtendedLayout = UIRectEdgeNone;
[self.view bringSubviewToFront:searchBarRef]; // add this line where ever u need..!
-(void)loadSearchBar {
searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, 320, 64)];
searchDisplayController = [[UISearchDisplayController alloc] initWithSearchBar:searchBar contentsController:self];
searchDisplayController.delegate = self;
searchDisplayController.searchResultsDataSource = self;
self.tableView.tableHeaderView = searchBar;
}
Call this loadSearchBar method at ViewDidLoad.
This will add search bar to TableView.
Through Storyboard, I have created a ViewController with a UITableView and a SegmentedControl on top. Programatially, I have added a SearchController as the TableView's header.
This is what happens when I launch the app:
It works perfectly.
But when I click on the search bar, it already messes up a bit. It's easy to fix by hiding the SegmentedControl though.
Now the problem appears when I finish my search:
The SegmentedControl disappears. Whenever I click on the searchbar again, it comes back, just like in the picture number 2, but if I cancel again, it disappears.
I have tried removing it from the view and adding it again once the user stops searching, but it changes nothing. Here is my code:
searchController = [[UISearchController alloc] initWithSearchResultsController:nil];
searchController.searchResultsUpdater = self;
searchController.dimsBackgroundDuringPresentation = NO;
searchController.searchBar.delegate = self;
self.tableView.tableHeaderView = searchController.searchBar;
searchController.searchBar.scopeButtonTitles = #[];
self.definesPresentationContext = YES;
[searchController.searchBar sizeToFit];
What can I change?
searchController.searchBar.showsScopeBar = YES;
I have a UITableView with a UISearchController search bar in the UINavigationBar, all works perfectly, but when I push a result of the searched results of the UISearchController, and I come back the UITableView is under the NavBar, this is how I initialize the UISearchController:
self.searchController = [[UISearchController alloc] initWithSearchResultsController:nil];
self.searchController.delegate = self;
self.searchController.searchResultsUpdater = self;
self.searchController.searchBar.delegate = self;
self.searchController.dimsBackgroundDuringPresentation = NO;
self.searchController.hidesNavigationBarDuringPresentation = NO;
self.searchController.searchBar.placeholder = NSLocalizedString(#"Local Search", #"");
self.searchController.searchBar.frame = CGRectMake(0, -5, [UIScreen mainScreen].bounds.size.width, 44);
ctrl = [[UIView alloc] initWithFrame:CGRectMake(0, 0,[UIScreen mainScreen].bounds.size.width, 44)];
ctrl.backgroundColor = [UIColor clearColor];
ctrl.autoresizingMask = UIViewAutoresizingFlexibleWidth;
[ctrl addSubview:self.searchController.searchBar];
self.navigationItem.titleView = ctrl;
self.definesPresentationContext = YES;
The search bar is displayed perfectly in the UINavigationBar, then when I search something and I push the view controller of one results like this:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[self.tableView deselectRowAtIndexPath:indexPath animated:YES];
DetailListController *detailList = [[DetailListController alloc] init];
[self.navigationController pushViewController:detailList animated:YES];
}
when I come back to the UITableView doing this:
[self.navigationController popViewControllerAnimated:YES];
the UITableView is under the UINavigationBar, how I can fix this?
thanks
I had exactly the same problem, setting extendedLayoutIncludesOpaqueBars to YES/true in view controller, that presents search controller, seems to fix it.
self.extendedLayoutIncludesOpaqueBars = YES
As a word of caution: setting this property changes value of scroll view's vertical content offset.
This is an extremely frustrating bug in UIKit. What appears to be happening is that the presenting view controller's top layout guide get reset to 0, meaning it is now underneath the nav bar. The layout guide is a read only property, so you can't fix it by editing directly. However, I did come up with a hack to get it to reset to the correct value. Add this to your UISearchControllerDelegate:
- (void)didDismissSearchController:(UISearchController *)searchController
{
UINavigationController *nav = self.navController; // you muse save this earlier
// force to layout guide to reset by pushing a dummy controller and popping it right back
[nav pushViewController:[UIViewController new] animated:NO];
[nav popViewControllerAnimated:NO];
}
I have used UISearchController for years but today is the first time I am facing this issue
I used to set edgesForExtendedLayout = [] and extendedLayoutIncludesOpaqueBars = true and everything is fine
but today It is not, I needed to reverse it to edgesForExtendedLayout = .all
it may be useful to you too!
Ran into this issue today and resolved using a reference to the result view controller's safeAreaLayoutGuide
After refreshing your result table's contents, you can then call this method:
// NOTE: this method is used to fix a known UIKit bug where search results that do not have a content
// size that fills the view will be placed underneath the navigation bar when displayed. this hack
// fixes this issue by resetting the contentInset based on the content size.
private func adjustContentInsetForContentSize() {
if collectionView.contentSize.height > view.frame.height {
collectionView.contentInset = UIEdgeInsets.zero
} else {
collectionView.contentInset = UIEdgeInsets(top: view.safeAreaLayoutGuide.layoutFrame.origin.y, left: 0, bottom: 0, right: 0)
}
}
Essentially the issue is caused by having a result view that has a contentSize height that is smaller than the viewable region for the view. The results render find when the contentSize.height > view.frame.height, so this hack will force the content insets to properly respect the safe area layout guide.
We have a UINavigationController with a UITableViewController. We have a UISearchController to filter the list of items in the table. When we tap a cell it navigates to the detail. But when we navigate back, its as if the UISearchBar is on top of the content... like instead of being in the table header, it is now over top of the table. How can we get it to behave as being in the table header.
func buildSearchBar() {
self.searchController.searchResultsUpdater = self
self.searchController.hidesNavigationBarDuringPresentation = false
self.searchController.dimsBackgroundDuringPresentation = false
self.definesPresentationContext = true
self.searchController.searchBar.sizeToFit()
self.tableView.tableHeaderView = searchController.searchBar
}
Edit to add: we set all UINavigationBar appearance to be translucent = NO; This is the line of code that seems to break it for us. Does that sound right to anyone else?
[UINavigationBar appearance].translucent = NO;
I had a similar problem. Add the following line to the viewDidLoad method of your view controller (self in the code you posted in your question).
self.definesPresentationContext = true;
This fixed the problem for me.
