UISearchController disable cancel UIBarButtonItem

Question

The Problem

I am trying to use UISearchController to search for a destination on a map view. I want the UISearchBar to appear in the navigation bar, but I can't seem to make it do so without it showing a cancel button to the right of it:

This Cancel button has disappeared at times, whilst I'm playing around, but I can't get it to not appear now I have got the search table showing how I want it to:

I'm sure there must be something small I'm doing ever so slightly wrong, but I can't work out what it is...

My Code

self.resultsViewController = [UITableViewController new];
self.searchController = [[UISearchController alloc] initWithSearchResultsController:self.resultsViewController];
self.searchController.searchResultsUpdater = self;
self.searchController.hidesNavigationBarDuringPresentation = false;
self.searchController.delegate = self;
self.searchBar = self.searchController.searchBar;
self.searchBar.placeholder = self.stage.title;
self.searchBar.searchBarStyle = UISearchBarStyleMinimal;

self.definesPresentationContext = true;
self.navigationItem.titleView = self.searchBar;

self.resultsTableView = self.resultsViewController.tableView;
self.resultsTableView.dataSource = self;
self.resultsTableView.delegate = self;

There is a way easier way...

For iOS 8, and UISearchController, use this delegate method from UISearchControllerDelegate:

func didPresentSearchController(searchController: UISearchController) {
  searchController.searchBar.showsCancelButton = false
}

Don't forget to set yourself as the delegate: searchController.delegate = self
