Adding UISearchController to UIView - ios

Question

I'm trying to add a UIViewSearchController to ad UIView however it does not seem to show? So far I've created a subclass of UISearchController and UISearchBar. I've done that to remove the cancel button, from the searchController. However since i added these custom classes the searchBar does not show in the View? How come this that?
viewDidLoad in viewcontroller
//SearchController
backSearchView.backgroundColor = UIColor.clearColor()
self.resultSearchController = ({
let controller = MySearchController(searchResultsController: nil)
controller.hidesNavigationBarDuringPresentation = false
controller.dimsBackgroundDuringPresentation = false
controller.searchResultsUpdater = self
controller.dimsBackgroundDuringPresentation = false
controller.searchBar.sizeToFit()
controller.searchBar.frame = CGRectMake(8, 8, self.view.frame.width-16, 44)
controller.searchBar.setShowsCancelButton(false, animated: false)
controller.searchBar.backgroundImage = UIImage()
controller.searchBar.placeholder = "Søg"
controller.searchBar.returnKeyType = UIReturnKeyType.Default
controller.searchBar.delegate = self
let textFieldInsideSearchBar = controller.searchBar.valueForKey("searchField") as? UITextField
textFieldInsideSearchBar?.backgroundColor = UIColor.whiteColor()
textFieldInsideSearchBar?.clipsToBounds = true
textFieldInsideSearchBar?.layer.cornerRadius = 1
textFieldInsideSearchBar?.layer.borderWidth = 2
textFieldInsideSearchBar?.layer.borderColor = UIColor.whiteColor().CGColor
textFieldInsideSearchBar?.textColor = UIColor.darkGrayColor()
backSearchView.addSubview(controller.searchBar)
return controller
})()
SearchController subclass
class MySearchController: UISearchController, UISearchBarDelegate {
lazy var customSearchBar: NoCancelSearchBar = {
[unowned self] in
let result = NoCancelSearchBar(frame:CGRectZero)
result.delegate = self
return result
}()
override var searchBar: UISearchBar {
get {
return customSearchBar
}
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
SearchBar subclass
class NoCancelSearchBar: UISearchBar {
override func layoutSubviews() {
self.showsCancelButton = false
}
}
