无法在 swift 中使用 CLPlacemark 获取子位置

Question

我实际上是在用 swift 构建一个应用程序。问题是应用程序应该从经度纬度获取子位置，并检查该 subLocality 是否是数组的一部分，但我无法获取子位置

这里的任何专业人士都可以帮助我吗

这是使用的经度纬度

let loc: CLLocation = CLLocation(latitude:43.60089111328125, longitude: 3.875329601741884)
ceo.reverseGeocodeLocation(loc, completionHandler: {(placemarks, error) in
                        if (error != nil)
                        {
                            print("reverse geodcode fail: (error!.localizedDescription)")
                        }
                        let pm = placemarks! as [CLPlacemark]
                        if pm.count > 0 {
                            let pm = placemarks![0]
                            addressString = ""
                            if pm.name != nil {
                                addressString += pm.name! + ", "
                            }
                            if pm.isoCountryCode != nil {
                                addressString += pm.isoCountryCode! + ", "
                            }
                            if pm.country != nil {
                                addressString += pm.country! + ", "
                            }
                            if pm.postalCode != nil {
                                addressString += pm.postalCode! + ", "
                            }
                            if pm.administrativeArea != nil {
                                addressString += pm.administrativeArea! + ", "
                            }
                            if pm.subAdministrativeArea != nil {
                                addressString += pm.subAdministrativeArea! + ", "
                            }
                            if pm.locality != nil {
                                addressString += pm.locality! + ", "
                            }
                            if pm.subLocality != nil {
                                addressString += pm.subLocality! + ", "
                            }
                            if pm.thoroughfare != nil {
                                addressString += pm.thoroughfare! + ", "
                            }
                            if pm.subThoroughfare != nil {
                                addressString += pm.subThoroughfare! + ", "
                            }
                            if pm.areasOfInterest != nil {
                                print(pm.areasOfInterest!)
                            }
     print(pm.addressDictionary)
}
})

这应该将 GAMBETTA 返回为子位置，但什么都没有发生。

Answer 1

您可以使用

Geocoder根据位置坐标进行反向地理编码，这将返回一个CLPlacemark，然后您可以检查是否存在subLocality，如下所示：

let geoCoder = CLGeocoder()
geoCoder.reverseGeocodeLocation(loc, completionHandler: { placemarks, error in
    // Place details
    guard let placeMark = placemarks?.first else { return }
    // SubLocality
    if let subLocality = placeMark.subLocality {
      // Do something if exists
    }
})

Answer 2

你能试试吗，它会帮助你的。

   let newlocation: CLLocation = CLLocation(latitude:43.60089111328125, longitude: 3.875329601741884)

        let geoCoder = CLGeocoder()
        geoCoder.reverseGeocodeLocation(newlocation, completionHandler: { (placemarks, error) -> Void in
            // Place details
            var placeMark: CLPlacemark!
            placeMark = placemarks?[0]
            print(placeMark.subLocality as Any)
            // Address dictionary
            print(placeMark.addressDictionary as Any)
            //City
            if let city = placeMark.addressDictionary!["City"] as? String {
                print("city : (city)")
            }
     })
