如何使用CLLocationManager获取附近的城市

Question

我知道如何获得当前的城市，但我还需要附近的城市名称......

locationManager.startUpdatingLocation() // start updating location
            locationManager.startMonitoringSignificantLocationChanges()
            currentLocation = self.locationManager.location != nil ? self.locationManager.location : nil
            if currentLocation != nil{ 
                geoCoder.reverseGeocodeLocation(currentLocation, completionHandler: {
                    placemarks, error in

                    if error == nil && placemarks!.count > 0 {
                        let placeArray = placemarks as [CLPlacemark]?
                        // Place details
                        let placeMark: CLPlacemark! = placeArray?[0]

                        // City
                        if let city = placeMark.addressDictionary?["City"] as? NSString {
                            self.city = city as String
                        }


                    }
                })

            }

我需要一个类似的功能来检索附近的城市名称..有没有办法使用CLLocationManager来做到这一点？ 似乎没有API可以做到这一点？ https://developer.apple.com/reference/corelocation/cllocationmanager
