Cannot Interact with SearchBar added as HeaderView - ios

I have added SearchController's searchbar to tableview controller's headerview but when I tap on the searchbar keyboard doesn't pop up. it feels like there is no user interaction. Following is the code used to add searchbar to uitableview.
self.resultSearchController = ({
let controller = UISearchController(searchResultsController: nil)
controller.searchResultsUpdater = self
controller.dimsBackgroundDuringPresentation = false
controller.searchBar.sizeToFit()
controller.searchBar.userInteractionEnabled = true
dispatch_async(dispatch_get_main_queue(),{
self.tableView.tableHeaderView = controller.searchBar
controller.searchBar.bounds = (self.tableView.tableHeaderView?.bounds)!
controller.definesPresentationContext = true
self.definesPresentationContext = true
})
return controller
})()

Try to add just this 5 lines of code in your viewDidLoad and give it a try
let searchController = UISearchController(searchResultsController: nil)
searchController.searchResultsUpdater = self
searchController.dimsBackgroundDuringPresentation = false
definesPresentationContext = true
self.tableView.tableHeaderView = searchController.searchBar

Why searchController nested in the tableView scrolled under the navigationBar?

I have tableViewController at the storyboard.
I programmatically added searchController to the table header.
private func setupSearchView(){
if !showSearchBar { return }
let storyboard = UIStoryboard(name: "Search", bundle: nil)
resultViewController =
storyboard.instantiateViewController(withIdentifier: "NewSearchTableViewController") as? SearchResultTableViewController
searchController = UISearchController(searchResultsController: resultViewController)
resultViewController?.tableView.delegate = self
searchController.delegate = self
searchController.searchResultsUpdater = self
searchController.searchBar.delegate = self // Monitor when the search button is tapped.
searchController.hidesNavigationBarDuringPresentation = false
searchController.dimsBackgroundDuringPresentation = false
tableView.tableHeaderView = searchController.searchBar
searchController.searchBar.sizeToFit()
searchController.searchBar.placeholder = "Search here...".localized
definesPresentationContext = true
}
When I selected the cell in the table and went to the details screen - it works perfectly.
But when I pressed button back, the search bar was scrolled under the navigation bar.
Normal behaiver
Bad behavior after button back pressed

How to fix jumping upon clicking search bar?

I've tried to add a simple search controller but whenever I'm clicking on it so it becomes active, it jumps up, out of screen. Why is that even happening? I checked all the code and I'm not manipulating with constraints or anything.
I initialize my search controller through the following function (and call it in ViewDidLoad):
private func initSearchController() {
self.searchController = ({
let controller = UISearchController(searchResultsController: nil)
controller.searchResultsUpdater = self
controller.searchBar.delegate = self
controller.dimsBackgroundDuringPresentation = false
controller.searchBar.sizeToFit()
controller.searchBar.barStyle = UIBarStyle.black
controller.searchBar.barTintColor = UIColor.white
controller.searchBar.backgroundColor = UIColor.clear
self.tableView.tableHeaderView = controller.searchBar
return controller
})()
self.tableView.reloadData()
}
self.searchController.hidesNavigationBarDuringPresentation = false

UISearchController view keeps getting pushed down when push-popping controllers from searchResultsController

I have a problem regarding the UISearchController component. I have set up a searchcontroller like this:
let searchResultsController = TSSearchResultsController(nibName: "TSSearchResultsController", bundle: nil)
searchResultsController.delegate = self
let searchController = UISearchController(searchResultsController: searchResultsController)
searchController.delegate = self
// SearchController
searchController.searchResultsUpdater = searchResultsController
searchController.hidesNavigationBarDuringPresentation = false
searchController.dimsBackgroundDuringPresentation = false
// SearchBar
searchController.searchBar.delegate = searchResultsController
searchController.searchBar.placeholder = NSLocalizedString("Search", comment: "")
searchController.searchBar.tintColor = IDAssetManager.getColorWhite()
searchController.searchBar.sizeToFit()
searchController.searchBar.searchBarStyle = .minimal
searchController.searchBar.showsCancelButton = false
self.definesPresentationContext = true
...
When I click the search result I push a view onto the navigationstack which is defined in the same place I initialise the searchController. When I come back, the searchController view has been pushed down a few a bit. This is continuously happening every time I push and pop from navigationController. I have tried self.extendedEdgesForLayout = [] but does not help.

swift search Bar and navigation bar will be hidden after starting

in my swift 2 app i have a table view with a search bar:
But if tap on the search bar, my navigation bar and the search bar will be hidden.
This is my code which is in the viewDidLoad
self.resultSearchController = ({
let controller = UISearchController(searchResultsController: nil)
controller.searchResultsUpdater = self
controller.dimsBackgroundDuringPresentation = false
controller.searchBar.sizeToFit()
controller.hidesNavigationBarDuringPresentation = true
self.MyTable.tableHeaderView = controller.searchBar
return controller
})()
At the beginning i also get this message:
Attempting to load the view of a view controller while it is
deallocating is not allowed and may result in undefined behavior
()
My Question is, where is my mistake? :/
from this tutorial you can use this code to solve the problem.
self.navigationController!.navigationBar.translucent = false
searchController!.hidesNavigationBarDuringPresentation = false
// This makes the view area include the nav bar even though it is opaque.
// Adjust the view placement down.
self.extendedLayoutIncludesOpaqueBars = true
self.edgesForExtendedLayout = UIRectEdge.Top
You have to modify your code with the below if you want to make it worked perfectly:
self.resultSearchController = UISearchController(searchResultsController: nil)
self.resultSearchController.searchResultsUpdater = self
self.resultSearchController.searchBar.delegate = self
self.definesPresentationContext = true
self.resultSearchController.dimsBackgroundDuringPresentation = false
self.resultSearchController.hidesNavigationBarDuringPresentation = true
if #available(iOS 11.0, *) {
self.navigationItem.searchController = self.resultSearchController
} else {
self.tableView.tableHeaderView = self.resultSearchController.searchBar
}

UISearchBar not firing

I put my UISearchController's search bar on navigation bar's titleView. But when I tap to search, UISearchBar does not respond. What can be the cause ?
let tvController:UITableViewController = UITableViewController()
tvController.tableView.delegate = self
tvController.tableView.dataSource = self
self.searchController = UISearchController(searchResultsController: tvController)
self.searchController?.searchResultsUpdater = self
self.searchController!.searchBar.placeholder = "Search for places"
self.searchController!.hidesNavigationBarDuringPresentation = false
self.searchController!.dimsBackgroundDuringPresentation = false;
self.searchController!.searchBar.searchBarStyle = UISearchBarStyle.Prominent
self.searchController!.delegate = self
self.searchController!.searchBar.delegate = self
self.definesPresentationContext = true
self.searchController!.searchBar.sizeToFit()
self.navigationItem.titleView = self.searchController!.searchBar
This might help
Replace
self.searchController = UISearchController(searchResultsController: tvController)
With
self.searchController = UISearchController(searchResultsController: nil)
