Search Bar disappeared from view while typing

Question

I added SearchBar to my TableView in ViewDidLoad() doing it:

    self.searchBar = UISearchController(searchResultsController: nil)
    self.searchBar.searchResultsUpdater = self

    self.searchBar.dimsBackgroundDuringPresentation = false
    self.searchBar.searchBar.sizeToFit()

    self.tableView.tableHeaderView = self.searchBar.searchBar
    self.tableView.reloadData()

everything works fine, but when I tap on this SearchBar it disappears. It means, I can still typing, and I can see the results but, don't see SearchBar. I implemented UISearchBarDelegate and I have been trying to add

func searchBarTextDidBeginEditing(searchBar: UISearchBar) {
    self.navigationController?.navigationBarHidden = false
}

func searchBarTextDidEndEditing(searchBar: UISearchBar) {
    self.navigationController?.navigationBarHidden = true
}

but it still doesn't work. Do you have any idea, why this Search Bar disappears?

solution of this problem is (like @sandy sad) write this line of code in viewDidLoad()

 self.aNavigationController?.extendedLayoutIncludesOpaqueBars = true

but now I have a new problem it's mean When I select row in TableView and display new VievController, SearchBar doesn't disappear and I see it in new view. Why?

Answer 1

You need to set extendedLayoutIncludesOpaqueBars to true in viewDidLoad().

self.aNavigationController?.extendedLayoutIncludesOpaqueBars = true
