Google Place Autocomplete不会显示任何搜索结果

Question

我正在使用Google地方自动填充功能。但是，当我尝试在搜索栏中键入任何单个位置时，结果为空，当我单击搜索栏时，它会向我提示以下消息。 （在此之前工作正常，能够搜索结果）

以下是一些代码，

override func viewDidLoad() {
    super.viewDidLoad()

    self.googleMapsView = GMSMapView(frame: self.mapView.frame)
    self.view.addSubview(self.googleMapsView)

    searchResultController = SearchResultsController()
    searchResultController.delegate = self
    gmsFetcher = GMSAutocompleteFetcher()
    gmsFetcher.delegate = self

    searchBar()
}


func searchBar() {
        self.searchController = UISearchController(searchResultsController: searchResultController)

        self.searchController.delegate = self
        self.searchController.searchBar.delegate = self

        self.searchController.hidesNavigationBarDuringPresentation = false
        self.searchController.dimsBackgroundDuringPresentation = true

        self.navigationItem.titleView = searchController.searchBar
        self.definesPresentationContext = true
    }
