Swift 3: press outside searchBar, search is automatic deleted - swift

Question

Configured a searcher in the navigation bar in a UITable. Everything is working fine, accept the fact that when I searched and found the needed cells and I want to click on that cell, the search term is quickly removed from the search bar. The result is that I get back the "old" table. I can not use the search results.
Class property: UITableViewController, ExpandableHeaderViewDelegate, UISearchBarDelegate, UISearchResultsUpdating {
var filteredArray = [Mijnproducten]()
var shouldShowSearchResults = false
override func viewDidLoad() {
super.viewDidLoad()
configureSearchController()
}
func configureSearchController() {
// Initialize and perform a minimum configuration to the search controller.
searchController.searchResultsUpdater = self
searchController.dimsBackgroundDuringPresentation = true
searchController.searchBar.placeholder = "Search here..."
searchController.searchBar.sizeToFit()
searchController.hidesNavigationBarDuringPresentation = false
// Place the search bar view to the tableview headerview.
self.navigationItem.titleView = searchController.searchBar
}
func searchBarTextDidBeginEditing(_ searchBar: UISearchBar) {
shouldShowSearchResults = true
searchWasCancelled = false
self.tableView.reloadData()
}
func searchBarCancelButtonClicked(_ searchBar: UISearchBar) {
shouldShowSearchResults = false
searchWasCancelled = true
self.tableView.reloadData()
}
func searchBarTextDidEndEditing(_ searchBar: UISearchBar) {
var searchTerm = ""
if searchWasCancelled {
searchController.searchBar.text = searchTerm
}
else {
searchTerm = searchController.searchBar.text!
}
}
func searchBarSearchButtonClicked(_ searchBar: UISearchBar) {
let text = searchController.searchBar.text
searchController.searchBar.text = text
if !shouldShowSearchResults {
shouldShowSearchResults = false
self.tableView.reloadData()
}
searchController.searchBar.resignFirstResponder()
}
func updateSearchResults(for searchController: UISearchController) {
let searchtext = searchController.searchBar.text
print(searchtext)
filteredArray = mijnproducten01.filter{ product in
return product.productname.lowercased().contains((searchtext?.lowercased())!)
}
print(filteredArray)
if searchtext?.isEmpty == false
{ shouldShowSearchResults = true }
else
{ shouldShowSearchResults = false }
// Reload the tableview.
self.tableView.reloadData()
}
}
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let indexPath = tableView.indexPathForSelectedRow
let currentCell = tableView.cellForRow(at: indexPath!) as! RowTableViewCell
let RowName = currentCell.ProductLine!.text
let temp = currentCell.UUID!.text
print("jaaaa", temp)
TAGID = Int(temp!)!
if RowName == "History"
{
tableView.deselectRow(at: indexPath!, animated: true)
self.performSegue(withIdentifier: "PropertyToHistory", sender: self)
}
else if RowName == "Description"
{
tableView.deselectRow(at: indexPath!, animated: true)
self.performSegue(withIdentifier: "PropertyToDescription", sender: self)
}
else if RowName == "Transfer"
{
tableView.deselectRow(at: indexPath!, animated: true)
self.performSegue(withIdentifier: "PropertyToTransfer", sender: self)
}
}

Answer 1

I would suggest you to put breakpoints on your searchBarTextDidBeginEditing,searchBarCancelButtonClicked,searchBarTextDidEndEditing,searchBarSearchButtonClicked and updateSearchResults.
When you select the cell and search result disappears then see where the breakpoint stops.
It seems that there could be logic issues with shouldShowSearchResults and searchWasCancelled.
Because from what you are saying is correct then somehow your searchController.searchBar.resignFirstResponder() is triggered which cancels the search. Putting up breakpoints and debugger will get you the culprit.
