I am unable to touch the view or scroll the tableview on didpresentSearchcontroller or willpresentSearchcontroller method of iOS 11 SearchController as shown in screenshot. There is some kind of dimming or UISearchView which not allowing me to touch the view controller or scroll the tableview. I think it disables the view.
The greycolor view is not letting me touch the viewcontroller or tableview.
How can i interact with viewcontroller or scroll the tableview.
I want to show result on this view controller only .
// I dont want to show anotherview controller as result
searchController = UISearchController(searchResultsController: nil)
I got it.
Use
let searchController = UISearchcontroller()
func willPresentSearchController(_ searchController: UISearchController) {
searchController.dimsBackgroundDuringPresentation = false
}
Since iOS 12 it is:
searchController.obscuresBackgroundDuringPresentation = false
You should add it before the refresh search.

I've embed UISearchController into the navigationbar and my view controller has the table view. When I click on searchbar and keyboard appears tableview and searchbar does not animate smoothly. It seems like searchbar is overlaping navigationbar.
Here is the code,
Declare searchcontroller as a variable like,
var resultSearchController = UISearchController()
and defination in viewDidLoad is like,
self.resultSearchController = ({
let controller = UISearchController(searchResultsController: nil)
controller.searchResultsUpdater = self
controller.obscuresBackgroundDuringPresentation = false;
self.navigationItem.searchController = controller
return controller
})()
Animation issue is like below gif(watch till end to see slow animation)
I want same duration for animation for tableview, navigation bar, and searchbar.
Any help will be appreciated.
Don't set UITableView top anchor to be pinned to safeArea but to superview.
Important extra note to the accepted answer:
If you use a UIViewController with subviews, including a UITableView, the UITableView has to be the first subview (i.e.: at index 0).
I AM NOT USING STORYBOARD SEGUES.
When I use UISearchController to have a search bar at the top of my table view, I get extremely strange behavior. Is there documentation on how I'm supposed to handle the search bar when a view dismisses? When I switch to a new view controller via an animation or push one on a nav stack, the bar is stuck in its spot until I hit the "Cancel" button.
See a video of what's happening in this short clip:
https://www.youtube.com/watch?v=6G7xFMENm_o&feature=youtu.be
This is the code, in the view controller, that sets up search bar:
var s: UISearchController!
private func configureSearching() {
s = UISearchController(searchResultsController: nil)
s.searchResultsUpdater = self
s.dimsBackgroundDuringPresentation = false
s.searchBar.searchBarStyle = .Minimal
s.hidesNavigationBarDuringPresentation = false
tableView.tableHeaderView = s.searchBar
s.searchBar.sizeToFit()
}
you should add the following line in viewDidLoad
self.definesPresentationContext = true
I have made a UITableView Controller with a UISearchBar as the Table's header.
I have then embedded this View Controller into a UINavigationController, as the root view controller.
Now, when I tap on the Search Bar, the SearchBar seems to disappears and displays a white screen. The keyboard appears, but there is no Search Bar.
The Table View can scroll, but the search bar has simply vanished.
When I implement this UITableViewController without the Navigation Controller, it works perfectly. But something about the Navigation Controller is borking everything up.
I've had the same issue that was sometimes happening, especially with table view of small number of rows (less than 50).
It appears the searchBar is removed from the view hierarchy, precisely from the container view that is a child of the UISearchControllerView.
I've found a workaround to manually add back the searchbar as a subview of the UISearchControllerView container child. This is implemented in the delegate function (from UISearchControllerDelegate) didPresentSearchController:
func didPresentSearchController(searchController: UISearchController) {
if searchController.searchBar.superview == nil {
for searchCtrlChildView in searchController.view.subviews {
if searchCtrlChildView.frame.origin == CGPoint(x: 0, y: 0) { //Discriminate if by chance there was more than one subview
searchCtrlChildView.addSubview(searchController.searchBar)
break
}
}
}
}
I've also filed a radar to Apple on this as it is not fixed in iOS 8.4
Check the way I had my searchBar it in viewDidLoad
I have my viewController embedded in NavigationController too
My code (hope it helps) :
class myTableViewController: UITableViewController,UISearchResultsUpdating,UISearchControllerDelegate,UISearchBarDelegate
override func viewDidLoad() {
super.viewDidLoad()
self.resultSearchController = ({
let controller = UISearchController(searchResultsController: nil)
controller.searchResultsUpdater = self
controller.dimsBackgroundDuringPresentation = false
controller.searchBar.sizeToFit()
self.tableView.tableHeaderView = controller.searchBar
return controller
})()
I have a problem with a UISearchBar. When ill search some Text in combination with an UITableView, and ill click on one result Cell, the UISearchBar is still visible in the next View Controller. If ill go back (with Segues) - the UISearchbar is still there (with the Keyword)
So after ill click on one result, ill get (in the next View Controller):
Ill use it this way:
class ...: UITableViewController, UISearchResultsUpdating {
var filterSearchController = UISearchController(searchResultsController: nil)
override func viewDidLoad() {
super.viewDidLoad()
filterSearchController.searchResultsUpdater = self
filterSearchController.hidesNavigationBarDuringPresentation = false
filterSearchController.dimsBackgroundDuringPresentation = false
filterSearchController.searchBar.searchBarStyle = .Minimal
filterSearchController.searchBar.sizeToFit()
self.tableView.tableHeaderView = filterSearchController.searchBar
Any ideas what could be a problem?
You need to dismiss the UISearchController yourself before transitioning to the next view controller with:
filterSearchController.active = false
I am relatively new to iOS (100 hours or so) and I am trying to implement a UISearchController without a storyboard. Is it possible to do this programmatically?
You have to implement UISearchController programmatically since Apple hasn't provided the ability to set it up using Storyboard yet.
Here are the steps to implement UISearchController in a view controller
Conform to UISearchResultsUpdating Protocol
Create a variable to reference the UISearchController
var searchController: UISearchController!
Set searchController in viewDidLoad(_:)
override func viewDidLoad() {
super.viewDidLoad()
searchController = UISearchController(searchResultsController: nil)
// The object responsible for updating the contents of the search results controller.
searchController.searchResultsUpdater = self
// Determines whether the underlying content is dimmed during a search.
// if we are presenting the display results in the same view, this should be false
searchController.dimsBackgroundDuringPresentation = false
// Make sure the that the search bar is visible within the navigation bar.
searchController.searchBar.sizeToFit()
// Include the search controller's search bar within the table's header view.
tableView.tableHeaderView = searchController.searchBar
definesPresentationContext = true
}
Implement the method updateSearchResultsForSearchController(_:), which is called when the search bar becomes the first responder or when the user makes changes to the text inside the search bar
func updateSearchResultsForSearchController(searchController: UISearchController) {
// No need to update anything if we're being dismissed.
if !searchController.active {
return
}
// you can access the text in the search bar as below
filterString = searchController.searchBar.text
// write some code to filter the data provided to your tableview
}
