The line countrySearch.delegate = self is giving me a fatal error.
"Thread 1: Fatal error: Unexpectedly found nil while unwrapping an Optional value"
My Code:
var searchedCountry = [String]()
var searching = false
@IBOutlet weak var countrySearch: UISearchBar!
@IBOutlet weak var tblView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
**countrySearch.delegate = self**
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
extension ViewController: UITableViewDelegate, UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if searching {
return searchedCountry.count
} else {
return countryNameArr.count
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell")
if searching {
cell?.textLabel?.text = searchedCountry[indexPath.row]
} else {
cell?.textLabel?.text = countryNameArr[indexPath.row]
}
return cell!
}
}
extension ViewController: UISearchBarDelegate {
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
searchedCountry = countryNameArr.filter({$0.lowercased().prefix(searchText.count) == searchText.lowercased()})
searching = true
tblView.reloadData()
}
func searchBarCancelButtonClicked(_ searchBar: UISearchBar) {
searching = false
searchBar.text = ""
tblView.reloadData()
}
}
