I'm using an UISplitViewController and on the detail view I have an UISearchController, but when the search bar gets active, the component suddenly goes to the right and half of it stay out of screen.
I tried to post the image, but sadly "You need at least 10 reputation to post images.", so I uploaded here http://iferiados.com.br/bug.jpg
It occurs only in the iPad and only when the display mode is .AllVisible, if I expand the detail view to all screen, the search bar stay in the correct place.
My code for the search controller:
var searchController: UISearchController!
//and in the viewDidLoad():
searchController = UISearchController(searchResultsController: nil)
searchController.hidesNavigationBarDuringPresentation = false
searchController.dimsBackgroundDuringPresentation = false
searchController.searchBar.placeholder = "Procure pelo nome"
searchController.searchBar.delegate = self
searchController.searchResultsUpdater = self
searchController.searchBar.sizeToFit()
tableView.tableHeaderView = searchController.searchBar
Thanks.
It doesn't look like you have any necessary constraints for the search bar. If you are configuring it through the storyboard then make sure you have all constraints or check out apple's documentation regarding constraints. Also, if you say the problem only occurs on the iPad, make sure that at the bottom of the storyboard "Any Any" is selected.

Left side displays my app in the iPhone 7 simulator. Right side is the app as displayed in my device. When tapping in the search bar, the navbar sildes up but then slides back down as showing in the image with the "What is this?" text.
The code for my search controller is as follows and it is being called in viewDidLoad.
//MARK: - Search Controller
func configureSearchController() {
searchController.dimsBackgroundDuringPresentation = false
definesPresentationContext = true
// to receive updates
searchController.searchResultsUpdater = self
// Set up searchbar of search controller
searchController.searchBar.scopeButtonTitles = ["All", "Something", "Something"]
searchController.searchBar.delegate = self
// add the searchbar to the tableview
tableView.tableHeaderView = searchController.searchBar
// hack to fix ocassional bugs
searchController.searchBar.sizeToFit()
}
Custom UITableViewController for UISearchController overlays the search bar in iOS 11 when you set the search controller to the navigationItem.searchController. The table view controller covers the whole screen so you cannot see the search bar while typing. This is not an issue when you send nil to UISearchController. Basically, I have a search bar for this map app, so I am setting a UITableViewController to the UISearchController to handle the display of the search result when searching for location. Previously, the table view shows up at the bottom of the search bar, now it covers the whole screen.
Here's a code snippet:
searchController = UISearchController(searchResultsController: searchResultsController)
searchController.searchBar.sizeToFit()
searchController.hidesNavigationBarDuringPresentation = true
searchController.dimsBackgroundDuringPresentation = true
searchController.definesPresentationContext = false
searchController.searchResultsUpdater = self
searchController.delegate = self
if #available(iOS 11.0, *){
self.navigationItem.searchController = searchController
}
Found the issue. Need to set the right origin value in willPresentSearchController
Upgrading our application to support iPhone X. How can I add a search bar to the header of a table view and have it within the safe zone? Here is how we currently build the search bar.
let searchController = UISearchController(searchResultsController: nil)
func buildSearchBar() {
self.searchController.searchResultsUpdater = self
self.searchController.hidesNavigationBarDuringPresentation = false
self.searchController.dimsBackgroundDuringPresentation = false
self.searchController.searchBar.sizeToFit()
self.tableView.tableHeaderView = searchController.searchBar
self.definesPresentationContext = true
}
This topic is discussed explicitly in Building Apps for iPhone X video. (Designing for iPhone X also a good video.)
Bottom line, Apple suggests using navigation controller and showing it there:
let searchController = UISearchController(searchResultsController: nil)
searchController.searchResultsUpdater = self
searchController.obscuresBackgroundDuringPresentation = false
if #available(iOS 11, *) {
navigationItem.searchController = searchController
searchController.isActive = true
} else {
present(searchController, animated: true)
}
(By the way, even in the absence of a navigation controller, present-ing the search controller, rather than setting it to be the table header, can prevent it from scrolling out of the safe area.)
Unclear what you mean by "within the safe zone". The table view can scroll, so the search bar is not necessarily "within" any part of the screen; it can be scrolled up behind the sensor area and on beyond.
You'll notice, however, that the native apps do not put the search bar as the header of the table. They put it in the navigation bar. You should do the same. Put the search bar into the navigation bar by setting the searchController of the navigationItem.
I'm having an issue with UISearchController. There have been some reports of erratic behavior in iOS 11, but none of the suggestions have fixed my problem.
The navigation bar is hidden in my app so I just want to place the search bar between two buttons on the main screen. I put UIView in the storyboard to serve as the superview for the search bar. When activated the results controller is a straight UITableViewController.
Everything is in-place when the app launches. When I access the search bar it just to the top of the screen, leaving it's parent view behind. Everything functions ok, but when I hide the table view, the search bar actual goes a bit lower than it was when it started. Here's the setup code:
let locationSearchTable = storyboard!.instantiateViewController(withIdentifier: "LocationSearchTable") as! LocationSearchTable
searchController = UISearchController(searchResultsController: locationSearchTable)
searchController.searchResultsUpdater = locationSearchTable
searchController.delegate = self
locationSearchTable.mapView = mapView
locationSearchTable.handleMapSearchDelegate = self
locationTableController = locationSearchTable
let searchBar = searchController!.searchBar
//searchBar.searchBarStyle = UISearchBarStyle.prominent
searchBar.sizeToFit()
searchBar.placeholder = "Search..."
searchViewHolder.addSubview(searchBar)
searchBar.frame = searchViewHolder.bounds
searchBar.autoresizingMask = [.flexibleWidth, .flexibleHeight]
searchController.dimsBackgroundDuringPresentation = true
definesPresentationContext = false
I have tried many, many approaches to fixing this. I'm wondering if I misunderstood an earlier suggestion. Any advice is welcome.
I'd the same issue. If your navbar is not translucent try to put this in viewDidLoad:
extendedLayoutIncludesOpaqueBars = true
I'm trying to keep the search bar in view as the table scrolls. At the moment I'm placing it as the header in a tableview, and it works as it should, but of course the search bar scrolls off screen as you go down the table. I thought I could do this simply modifying this code sample:
How do I use UISearchController in iOS 8 where the UISearchBar is in my navigation bar and has scope buttons?
searchController = UISearchController(searchResultsController: nil)
searchController.searchResultsUpdater = self
searchController.delegate = self
searchController.searchBar.delegate = self
searchController.dimsBackgroundDuringPresentation = false
searchController.hidesNavigationBarDuringPresentation = false
tableview.tableHeaderView = searchContoller.searchBar // How to put it elsewhere?
//Alternative that also works
navigationItem.titleView = searchController.searchBar
The idea was to take some other view and do
otherview = searchController.searchBar
For instance an outlet to a UISearchBar, or a blank UIView, or something like that.
But it doesn't show the searchBar if I do that. It seems to only work as the header view of a table or as a navigationItem.titleView.
Am I missing something?
If you have a blank UIView that is placed above the tableview.
let's assume you have an outlet to that blank UIView called searchContainer.
Then you can add the search bar of the UISearchController to that view by adding the following line
searchContainer.addSubview(searchController.searchBar)
