GMSPlace returns 无效坐标（-180，-180），但名称和地点 ID 正确

Question

我正在尝试在 Google 地图上实现自动完成搜索，该搜索将使用标记显示用户 select 在地图上的位置。

搜索正常。问题如下。当我 select 从搜索结果中找到一个位置时，我得到一个 GMSPlace 对象，该对象具有与 selected 值一样的正确名称、正确的地点 ID（使用此 link 确认），但不正确坐标（-180.0,-180.0，或 kCLLocationCoordinate2DInvalid 常量）。我在多个位置对此进行了测试。

此代码的大部分是从 documentation 借用的地方 API。

import UIKit
import GoogleMaps
import GooglePlaces

class ViewController: UIViewController, UISearchBarDelegate {

    @IBOutlet weak var mapContainer: UIView!
    var mapView: GMSMapView!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        self.mapView = GMSMapView(frame: self.mapContainer.frame)
        self.view.addSubview(self.mapView)
    }

    // Code from https://developers.google.com/places/ios-sdk/autocomplete#add_an_autocomplete_ui_control
    @IBAction func searchByAddress(_ sender: Any) {
        // Present the Autocomplete view controller when the button is pressed.
        let autocompleteController = GMSAutocompleteViewController()
        autocompleteController.delegate = self

        // Specify the place data types to return.
        let fields: GMSPlaceField = GMSPlaceField(rawValue: UInt(GMSPlaceField.name.rawValue) |
            UInt(GMSPlaceField.placeID.rawValue))!
        autocompleteController.placeFields = fields

        // Display the autocomplete view controller.
        present(autocompleteController, animated: true, completion: nil)
    }
}

extension ViewController: GMSAutocompleteViewControllerDelegate {

    // Handle the user's selection.
    func viewController(_ viewController: GMSAutocompleteViewController, didAutocompleteWith place: GMSPlace) {
        let position: CLLocationCoordinate2D = place.coordinate

        let camera = GMSCameraPosition.camera(withLatitude: position.latitude, longitude: position.longitude, zoom: 10)
        let newMapView = GMSMapView.map(withFrame: self.mapContainer.frame, camera: camera)
        self.mapView = newMapView
        self.view.addSubview(newMapView)

        let marker = GMSMarker()
        marker.position = position
        marker.title = place.name
        marker.map = self.mapView

        viewController.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) {
        viewController.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
    }

}

如有任何帮助，我们将不胜感激！

我遇到了同样的问题并浏览了 Place SDK 文档，该文档清楚地说明我们应该事先向 GMSPlaceField 定义我们究竟需要哪些细节，如果您完全遵循该文档，结果将是仅在正在填充的名称和 placeId 中。因此，在实例化您的 GMSAutoCompleteViewController 时，请按以下方式定义。

**let fields: GMSPlaceField = GMSPlaceField(rawValue:UInt(GMSPlaceField.name.rawValue) |
            UInt(GMSPlaceField.placeID.rawValue) |
            UInt(GMSPlaceField.coordinate.rawValue) |
            GMSPlaceField.addressComponents.rawValue |
            GMSPlaceField.formattedAddress.rawValue)!
autocompleteController.placeFields = fields**

GMSPlace returns 无效坐标（-180，-180），但名称和地点 ID 正确

GMSPlace returns invalid coordinate (-180, -180), but name and place ID are correct
