Question

我试图用swift获取当前城市名称和国家/地区名称。这是我的源代码。 //然后在CLLocationManagerDelegate方法中，您可以获取用户的当前位置坐标：

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    let locValue:CLLocationCoordinate2D = manager.location!.coordinate
    print("locations = \(locValue.latitude) \(locValue.longitude)")
    self.locationManager.stopUpdatingLocation()
    getAddressFromGeocodeCoordinate(manager.location!)

}

func getAddressFromGeocodeCoordinate(locationObj: CLLocation) {
    let geocoder = CLGeocoder()
    geocoder.reverseGeocodeLocation(locationObj, completionHandler: { (placemarks, error) -> Void in

        // Place details
        var placeMark: CLPlacemark!
        placeMark = placemarks?[0]

        // Address dictionary
        print(placeMark.addressDictionary)

        // City
        if let city = placeMark.addressDictionary!["City"] as? NSString {
            print("city:",city)
        }

        // Country
        if let country = placeMark.addressDictionary!["Country"] as? NSString {
            print("country", country)
        }

    })
}

但是当我想打印城市时，它返回零。我也trid placeMark.subAdministrativeArea但它也返回nil。

我目前位于丹东市。

我的代码打印好国家。比如country China但是城市。

有谁知道解决方案？

检查是否有任何错误或获得print(placeMark.addressDictionary)

的响应

geocoder.reverseGeocodeLocation(newLocation, completionHandler: {(stuff, error)->Void in

        if error {
            println("reverse geodcode fail: \(error.localizedDescription)")
            return
        }

        if stuff.count > 0 {
            self.placemark = CLPlacemark(placemark: stuff[0] as CLPlacemark)

            self.addressLabel.text = String(format:"%@ %@\n%@ %@ %@\n%@",
                self.placemark.subThoroughfare ? self.placemark.subThoroughfare : "" ,
                self.placemark.thoroughfare ? self.placemark.thoroughfare : "",
                self.placemark.locality ? self.placemark.locality : "",
                self.placemark.postalCode ? self.placemark.postalCode : "",
                self.placemark.administrativeArea ? self.placemark.administrativeArea : "",
                self.placemark.country ? self.placemark.country : "")
        }
        else {
            println("No Placemarks!")
            return
        }

        })

使用CLGeocoder无法在swift中获得正确的城市名称
