How do I dismiss a UISearchController view? - ios

Question

Context: There's a map view with a UISearchController implemented. The search controller displays its results in a different table view controller
I found this answer which explains how to dismiss the search controller within the same view. However, my results page is a different view than its origin page. I have
let resultsPage = ResultsTableViewController()
let searchController = UISearchController(searchResultsController: resultsPage)
So now when the search controller gets results, it displays them on the table view controller. When the user selects one of the results, I want to dismiss this view and go back to the map view, passing their selection along. Should I do this with a segue, or is there a better programmable approach?

Did this same thing in my app. My map view controller has a search bar. When the user enters a search string, it presents a table view controller with a list of addresses that were found. The user can select an address which then dismisses the table view controller and drops a pin on the map for the selected address.
In the table view that displays, use didSelectRowAtIndexPath to dismiss the table view controller and use a protocol/delegate to pass the selected item back to the map view controller. Have your map view controller conform to this protocol. I did this exact setup and it works well.
protocol DropPinOnSelectedLocationDelegate {
func dropPinOnLocation(placemark:MKPlacemark)
}
class LocationSearchTable: UITableViewController {
...
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
let cell = tableView.cellForRowAtIndexPath(indexPath)
self.mySearchController.searchBar.endEditing(true)
if let indexPath = tableView.indexPathForCell(cell!) {
selectedItem = matchingItems[indexPath.row].placemark
}
self.dismissViewControllerAnimated(true, completion: {
self.delegate?.dropPinOnLocation(self.selectedItem!)
})
}
}
