如何在 iOS 中仅过滤 GMSAutocompleteResultsViewController 中的学校？

Question

我正在使用 GMSAutocompleteResultsViewController 搜索 iOS 中的地点。我写下地名并根据关键字获得结果。但问题是我只想搜索学校。因此，如果我输入任何地名，如果它是学校，那么我应该出现在结果中，否则不会。

GMSAutocompleteFilter 只显示一些过滤器，如机构、地区、城市、地址等，但在 android 中它有过滤器作为学校

下面是我用于搜索的代码。

class SearchLocationController: DIBaseController {

    var resultsViewController: GMSAutocompleteResultsViewController?
    var searchController: UISearchController?
    var resultView: UITextView?

    override func viewDidLoad() {
        super.viewDidLoad()

        resultsViewController = GMSAutocompleteResultsViewController()
        resultsViewController?.delegate = self

        searchController = UISearchController(searchResultsController: resultsViewController)
        searchController?.searchResultsUpdater = resultsViewController

        let filter = GMSAutocompleteFilter()
        filter.type = .establishment
        resultsViewController?.autocompleteFilter = filter

        // 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
    }
}

// Handle the user's selection.
extension SearchLocationController: GMSAutocompleteResultsViewControllerDelegate {
    func resultsController(_ resultsController: GMSAutocompleteResultsViewController,
                           didAutocompleteWith place: GMSPlace) {
        searchController?.isActive = false
        // Do something with the selected place.

    }

    func resultsController(_ resultsController: GMSAutocompleteResultsViewController,
                           didFailAutocompleteWithError error: Error){
        // TODO: handle the error.
        print("Error: ", error.localizedDescription)
    }

    // Turn the network activity indicator on and off again.
    func didRequestAutocompletePredictions(_ viewController: GMSAutocompleteViewController) {
        UIApplication.shared.isNetworkActivityIndicatorVisible = true
    }

    func didUpdateAutocompletePredictions(_ viewController: GMSAutocompleteViewController) {
        UIApplication.shared.isNetworkActivityIndicatorVisible = false
    }
}

显然，在iOS SDK中，支持的地方类型只有geocode、address、establishment、region和city.
