谷歌地图在iOS Swift中按纬度和经度放置信息

Question

我在地图上有一个标记。滚动地图时，标记也会移动。我可以找到标记坐标，但是如何使用该坐标找到地点信息？

当前位置的地点信息

func locate() {
        placesClient.currentPlace(callback: { (placeLikelihoodList, error) -> Void in
            if let error = error {
                print("Pick Place error: \(error.localizedDescription)")
                return
            }
            
            let placeInfo = getCurrentPlaceInformation()
            self.placeNameLbl.text = placeInfo.name
            self.placeAddressLbl.text = placeInfo.address
            
            if let placeLikelihoodList = placeLikelihoodList {
                let place = placeLikelihoodList.likelihoods.first?.place
                if let place = place {
                    print("LOG: place name : \(place.name), place Address : \(place.formattedAddress)")
                    
                    PLACE_NAME = place.name
                    PLACE_ADDRESS = place.formattedAddress ?? ""
                    
                    let placeInfo = getCurrentPlaceInformation()
                    self.placeNameLbl.text = placeInfo.name
                    self.placeAddressLbl.text = placeInfo.address
                }
            }
        })
    }

如何通过自定义坐标查找地点信息？

Apple 反向地理编码 API

import CoreLocation
let geocoder = CLGeocoder()
geocoder.reverseGeocodeLocation(<#T##location: CLLocation##CLLocation#>, completionHandler: <#T##CLGeocodeCompletionHandler##CLGeocodeCompletionHandler##([CLPlacemark]?, Error?) -> Void#>)

将 GoogleMaps 添加到项目中（可以使用 pod）

let geocoder = GMSGeocoder()
geocoder.reverseGeocodeCoordinate(position) { response, error in
  //
if error != nil {
                print("reverse geodcode fail: \(error!.localizedDescription)")
            } else {
                if let places = response?.results() {
                    if let place = places.first {


                        if let lines = place.lines {
                            print("GEOCODE: Formatted Address: \(lines)")
                        }

                    } else {
                        print("GEOCODE: nil first in places")
                    }
                } else {
                    print("GEOCODE: nil in places")
                }
            }
}
