UISearchController iOS 11 Customization

Question

I had been using the following code prior to iOS 11 to customize the appearance of the UISearchController search bar:

var searchController = UISearc         


        

Answer 1

Try it: searchController..barStyle = .blackOpaque instead of self.searchBarStyle = .minimal.

Thus:

var searchController = UISearchController(searchResultsController: nil)
searchController.searchBar.setDefaultSearchBar()
//Add this line below
searchController.searchBar.barStyle = .blackOpaque
searchController.searchResultsUpdater = self

if #available(iOS 11.0, *) {
    navigationItem.searchController = searchController
} else {
    tableView.tableHeaderView = searchController.searchBar
}

extension UISearchBar {
    func setDefaultSearchBar() {
        self.tintColor = UIColor.blue
        //Delete this line below
        self.searchBarStyle = .minimal
        self.backgroundImage = UIImage(color: UIColor.clear)
        let searchBarTextField = self.value(forKey: "searchField") as! UITextField
        searchBarTextField.textColor = UIColor.white
        searchBarTextField.tintColor = UIColor.blue
        searchBarTextField = .dark
    }
}
