Swift google 使用本地搜索自动完成

Question

我正在尝试使用 Swift 3.0 中的 Google 个位置进行 Google 自动完成。但我需要根据我当前的位置进行搜索。例如，如果我在印度加尔各答，输入搜索关键字 "Ko"，它将首先显示加尔各答的结果。

谁能帮帮我。这是我的代码。我在 class

中导入 Google 个位置

@IBAction func txtFieldLocationDidStartEditing(_ sender: Any) {   
  self.placeAutocomplete()
}
func placeAutocomplete() {
    let autocompleteController = GMSAutocompleteViewController()
       autocompleteController.delegate = self
   present(autocompleteController, animated: true, completion: nil)
}

// 标记：- 自动完成代表

func viewController(_ viewController: GMSAutocompleteViewController, didAutocompleteWith place: GMSPlace) {
    print("Place name: \(place.name)")
    dismiss(animated: true, completion: nil)
}

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

// User canceled the operation.
func wasCancelled(_ viewController: GMSAutocompleteViewController) {
    dismiss(animated: true, completion: nil)
}

// 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
}

请大家帮我解决一下。提前致谢。

GMSAutocompleteViewController 提供的唯一 API 是像这样设置 GMSCoordinateBounds (reference):

func placeAutocomplete() {
    let visibleRegion = mapView.projection.visibleRegion()
    let bounds = GMSCoordinateBounds(coordinate: visibleRegion.farLeft, coordinate: visibleRegion.nearRight)

    let autocompleteController = GMSAutocompleteViewController()
    acController.autocompleteBounds = bounds
    autocompleteController.delegate = self
    present(autocompleteController, animated: true, completion: nil)
}
