【问题描述】：

我实际上正在快速构建一个应用程序。 问题是应用程序应该从经度纬度获取子位置并检查该子位置是否是数组的一部分，但我无法获得子位置

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)

)

应该将 GAMBETTA 作为 subLocality 返回，但什么都不会发生。

“什么都不会发生”，因为您没有要求子地区性。

【参考方案1】：

您可以根据位置坐标使用Geocoder 进行反向地理编码，这将返回CLPlacemark，然后您可以检查subLocality（如果存在），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
    
)

【参考方案2】：

你能不能试试，对你有帮助。

   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)")
            

     )
