UISearchController invokes Swift 2.0 black screen

Question

I have a strange problem in iOS 9 with Swift 2.0 . I added a UISearchController to my tableViewController , but this causes a strange black screen problem. When I click on the search bar and write something, it shows the filtering results without any problems, but when I click on another button of the tab bar, for example Bookmarks , and after that when I click on tableViewController, which is Most popular again shows the black screen like a screen.

There is my tableViewController ;

 import UIKit class CitiesTableViewController: UITableViewController, UISearchResultsUpdating { // MARK: - Class Properties private var cities = [String]() private var veterinaries = [Veterinary]() private var filteredVeterinaries = [Veterinary]() private var resultSearchController: UISearchController! // MARK: - TableViewController Life Cycle Methods override func viewDidLoad() { super.viewDidLoad() self.getCitiesList() self.configureResultsSearchController() } override func viewDidDisappear(animated: Bool) { super.viewDidDisappear(animated) self.resultSearchController.active = false } // MARK: - Configuring Search Bar Controller private func configureResultsSearchController() { self.resultSearchController = UISearchController(searchResultsController: nil) self.resultSearchController.searchResultsUpdater = self self.resultSearchController.dimsBackgroundDuringPresentation = false self.resultSearchController.hidesNavigationBarDuringPresentation = false self.resultSearchController.searchBar.sizeToFit() self.resultSearchController.searchBar.placeholder = "Klinik veya ilçe adı" self.tableView.tableHeaderView = self.resultSearchController.searchBar } // MARK: - Table view data source override func numberOfSectionsInTableView(tableView: UITableView) -> Int { return 1 } override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int { if self.resultSearchController.active { return self.filteredVeterinaries.count } else { return self.cities.count } } // MARK: - Table view Delegate Methods override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { if (self.resultSearchController.active) { self.performSegueWithIdentifier(Constants.ShowDetailViewControllerSegueIdentifier, sender: nil) } else { self.performSegueWithIdentifier(Constants.ShowTownsTableViewControllerSegueIdentifier, sender: nil) } } override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { let cell = tableView.dequeueReusableCellWithIdentifier(Constants.CellIdentifier, forIndexPath: indexPath) if (self.resultSearchController.active) { cell.textLabel?.text = self.filteredVeterinaries[indexPath.row].name cell.detailTextLabel?.text = self.filteredVeterinaries[indexPath.row].address return cell } else { cell.textLabel?.text = self.cities[indexPath.row] return cell } } // MARK: - PARSE Query Methods private func getCitiesList() { let parseQueries = ParseQueries() parseQueries.downloadListData() { (let parseResults) in if let veterinaries = parseResults as? [Veterinary] { self.veterinaries = veterinaries for vet in veterinaries { if let city = vet.city { self.cities.append(city) } } dispatch_async(dispatch_get_main_queue()) { self.cities = HelperMethods().removeDuplicatesAndSort(array: self.cities) self.tableView.reloadData() } } } } // MARK: - UISearchController Delegate Methods func updateSearchResultsForSearchController(searchController: UISearchController) { self.filteredVeterinaries.removeAll(keepCapacity: false) if let searchBarText = searchController.searchBar.text{ let searchText = searchBarText.lowercaseString // Searching with Veterinary Name and Veterinary City self.filteredVeterinaries = self.veterinaries.filter({$0.name?.lowercaseString.rangeOfString(searchText) != nil}) self.filteredVeterinaries += self.veterinaries.filter({$0.town?.lowercaseString.rangeOfString(searchText) != nil}) tableView.reloadData() } } 

This is a black screen image from the iOS 9 simulator, the same as the real device.

I think it deinits my tableView when I click on searchBar and it cannot be initialized again. Is this a mistake or something else?

How can I solve this problem?

Thanks!

Answer 1

Friend, in viewDidLoad() paste this line of code:

 self.definesPresentationContext = true 

See how I put it (line 29):

I recently ran into the same problem and I could easily fix it. self.definesPresentationContext = true already defined in viewDidLoad () , but this did not solve this problem.

In the question above, maybe you are showing the CitiesTableViewController directly when you click on the MostViewed element.

To avoid a black screen, you can embed the CitiesTableViewController in the UINavigationController and try to show the navigation controller when you click on the tab element.

This solution avoids the black screen problem.
