how to hide the navigation bar after dismissing from searchController - ios

Question

I have two viewControllers ControllerA and ControllerB. Both doesn't have NavigationBar as I have hided the navigationBar in both the controllers. On ControllerB there is a a tableview and on top of that is a searchBar. On selection of any tablerow I am dismissing the controller back to ControllerA. The problem is it shows some Bar on controllerA and I don't know how to hide it.If I don't search anything and Press the back Button on controller B then no navigationBar appears on the ControllerA. But If I select something then it shows. I think its something to do with the searchBar Presentation. Here is my code
ControllerB
override func viewDidLoad() {
super.viewDidLoad()
self.resultSearchController = ({
let controller = UISearchController(searchResultsController: nil)
controller.searchResultsUpdater = self
controller.dimsBackgroundDuringPresentation = false
controller.searchBar.sizeToFit()
controller.searchBar.placeholder = "Search City"
self.tableView.tableHeaderView = controller.searchBar
self.definesPresentationContext = true
return controller
})()
self.tableView.reloadData()
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if (self.resultSearchController.active) {
return self.filteredKeys.count
} else {
return dict.count-1
}
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! CountryTableViewCell
if(self.resultSearchController.active){
// let key = self.filteredKeys[indexPath.row]
//let dictionary = self.dict[key] as! NSDictionary
let cityName = (((self.dict["\(indexPath.row)"] as?NSDictionary)!["Country"] as?NSDictionary)!["city_name"] as?NSString)
let stateName = (((self.dict["\(indexPath.row)"] as?NSDictionary)!["Country"] as? NSDictionary)!["state_name"] as? NSString)
let shortName = (((self.dict["\(indexPath.row)"] as?NSDictionary)!["Country"] as? NSDictionary)!["short_country_name"] as? NSString)
if (cityName !== "-" || shortName !== "-"){
cell.stateNameLabel.text = stateName as? String
cell.cityNameLabel.text = cityName as? String
cell.shortNameLabel.text = shortName as? String
}
}
return cell
}
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
let id = Int((((dict["\(indexPath.item)"] as?NSDictionary)!["Country"] as?NSDictionary)!["id"] as?NSString)! as String)
let cityName = (((dict["\(indexPath.item)"] as?NSDictionary)!["Country"] as?NSDictionary)!["city_name"] as?NSString)! as String
let countryShortName = (((dict["\(indexPath.item)"] as?NSDictionary)!["Country"] as?NSDictionary)!["short_country_name"] as?NSString)! as String
delegate.country(id!,cityName: cityName, countryShortName: countryShortName,departureOrArrivalSegue: departureOrArrivalSegue!)
self.navigationController!.popViewControllerAnimated(true)
}

You can just use
self.navigationController?.setNavigationBarHidden(true, animated: true)
