Summary:
I'm trying to subclass UISearchController to customize the searchBar. I want it to not show the cancel button. 
However, once I use this new subclass, searchResultsController controller is not presented and presentSearchController is not called if I implement it on the delegate.

Steps to Reproduce:
1. Open the attached project (created from https://developer.apple.com/library/ios/samplecode/TableSearch_UISearchController/Introduction/Intro.html) and available on https://www.dropbox.com/s/i9n46a87z3qgz4v/TableSearch.swift.zip?dl=0.

2. Run the project
3. Try to search
4. Observe that the results are not updated, because the view controller that filters them never gets presented!

PS: The relevant code is on MainTableViewController, mainly CustomSearchController and MainTableViewController.viewDidLoad()

Expected Results:
I’d expected that the UISearchController worked flawlessly and the searchBar cancel button was hidden.

Actual Results:
UISearchController doesn’t show at all.

Regression:
UISearchController is new on iOS 8. 

Notes:
1. The docs for UISearchController clearly recommends to subclass (https://developer.apple.com/library/prerelease/ios/documentation/UIKit/Reference/UISearchController/index.html#//apple_ref/occ/instp/UISearchController/searchBar). Quoting here:

“To create a custom UISearchBar, subclass the UISearchController class and return your custom object."


2. There’s a post on StackOverflow from an Apple iOS Frameworks Engineer stating that it’s a bug (http://stackoverflow.com/questions/25904213/custom-uisearchbar-with-uisearchcontroller/25940619#25940619).

3. I’d like to replicate the behavior from App Store.app on iPhone, where I have a tab just for search. Notice that it doesn’t show the cancel button in any button.

4. I can get the expected result by using UISearchDisplayController, which I believe is what App Store.app is using.

5. This bug was filled after DTS #616849108 (requested by the engineer involved).
