UISearchController - Keyboard not showing

Question

I am using the UISearchController and the search function works except for two things. Perhaps they are related: a) The keyboard does not show. So I cannot press the "Search" button b) In my main TableView I access the prototype cell that has the style "Subtitle". When the search is going on, the cell that shows is "Basic" style. In both cases (TableViewController and SearchViewController) I use the same cell identifier.

Any ideas? Here some of the code:

class OverviewTableViewController: UITableViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        let resultsController = SearchResultsController()
        resultsController.birds = birds
        searchController = UISearchController(searchResultsController: resultsController)
        //searchController.dimsBackgroundDuringPresentation = true

        let searchBar = searchController.searchBar
        searchBar.scopeButtonTitles = ["One", "Two"]
        searchBar.placeholder = "Search"
        searchBar.sizeToFit()
        tableView.tableHeaderView = searchBar
        searchController.searchResultsUpdater = resultsController

and the second class:

class SearchResultsController: UITableViewController, UISearchResultsUpdating {

    var items: [Item] = []
    var filtered: [Item] = []

override func viewDidLoad() {
    super.viewDidLoad()
    tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "cell")
}

// MARK: - UISearchResultsUpdating Conformance

func updateSearchResultsForSearchController(searchController: UISearchController) {
    //searchController.hidesNavigationBarDuringPresentation = true
    let searchString = searchController.searchBar.text
    let buttonIndex = searchController.searchBar.selectedScopeButtonIndex
    filtered.removeAll(keepCapacity: true)

    if !searchString.isEmpty {
        for item in items {
            ...
            }
        }

    self.tableView.reloadData()

    }
}

For your first problem 'a)', are you testing in the Simulator or a device? If in the Simulator, try tapping ⌘K (command-k). — benhameen
Also, could you show us some relevant code so that we can help you a bit more? Perhaps some of the delegate/datasource methods of both controllers? — benhameen
benhameen - thanks I was able to get the keyboard with the shortcut. — Pete

I had the same issue and basically if your parent class has a UISearchController as well as your child class and you're setting the

self.definesPresentationController = YES

in your parent class, your child class' search controller won't have the keyboard showing. Took me a while to figure out but this is what is happening.

The way to fix it is to set the self.definesPresentationController = NO when your parent class is about to push the child class and set self.definesPresentationController = YES in the viewWillAppear of your parent class...

Hope this helps someone out there too.
