在UIViewController中点击搜索栏文本字段时,应用程序崩溃

我的ViewController看起来像这样 -

class DetailViewController: UIViewController, GMSMapViewDelegate, UISearchBarDelegate {

let testBaseUrl = "https://maps.googleapis.com/maps/api/geocode/json?"

var searchBar = UISearchBar()
var searchImageView   : UIImageView!
var mapView: GMSMapView!
var markers = [GMSMarker]()
var cameraPosition: GMSCameraPosition!
var searchAddress: String!

var mapButton = UIBarButtonItem()
var listButton = UIBarButtonItem()
var filterButton = UIBarButtonItem()
var arrayOfButtons = [AnyObject]()

override func viewDidLoad() {
    super.viewDidLoad()

    cameraPosition = GMSCameraPosition.cameraWithLatitude(-37.809487,
        longitude:144.965699, zoom:17.5, bearing:30, viewingAngle:40)
    mapView = GMSMapView.mapWithFrame(CGRectZero, camera:cameraPosition)

    mapView.delegate = self
    self.view = mapView

}

override func viewWillAppear(animated: Bool) {
    setUISearchView()

} …
