Swift 2 Mapkit从用户位置获取城市

let locationManager = CLLocationManager()
locationManager.requestWhenInUseAuthorization()

locationManager.delegate = self
locationManager.startUpdatingLocation()

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    if let location = locations.last {
        // 获取用户位置的经纬度坐标
        let coordinate = location.coordinate
        
        // 创建一个地理编码器
        let geocoder = CLGeocoder()
        
        // 使用地理编码器将经纬度转换为地理位置信息
        geocoder.reverseGeocodeLocation(location) { (placemarks, error) in
            if let error = error {
                print("Reverse geocoding failed: \(error.localizedDescription)")
                return
            }
            
            if let placemark = placemarks?.first {
                // 获取城市信息
                if let city = placemark.locality {
                    print("City: \(city)")
                    // 在这里可以使用获取到的城市信息进行后续操作
                }
            }
        }
    }
