我正在将GMSAutocompleteResultsViewController用于谷歌自动完成搜索位置。当我用它搜索时，它显示的结果非常有限。它没有显示所有结果。此外，当它在 android 中使用时，它显示了许多结果。请让我知道我错过了什么。
override func viewDidLoad() {
super.viewDidLoad()
resultsViewController = GMSAutocompleteResultsViewController()
resultsViewController?.delegate = self
searchController = UISearchController(searchResultsController: resultsViewController)
searchController?.searchResultsUpdater = resultsViewController
// Put the search bar in the navigation bar.
searchController?.searchBar.sizeToFit()
navigationItem.titleView = searchController?.searchBar
// When UISearchController presents the results view, present it in
// this view controller, not one further up the chain.
definesPresentationContext = true
// Prevent the navigation bar from being hidden when searching.
searchController?.hidesNavigationBarDuringPresentation = false
}
