如何将地理坐标转换成准确的地址？

Question

我想将用户的位置，其中包含纬度和经度的值，转换成准确的地址。但是它不起作用，它在执行后返回一个空字符串。

此外，Xcode建议我使用CNPostalAddress，我不知道它是什么。

这是函数

import Foundation
import CoreLocation
import AddressBook`

    func reverseGeocoder()->String{
        let info:String?
        var geocoder = CLGeocoder()
        var currentUserLocation = CLLocation(latitude: 30, longitude: 122)
        geocoder.reverseGeocodeLocation(currentUserLocation, completionHandler: {
            (placemarks,error) -> Void in
            if placemarks != nil && placemarks?.count > 0{
                let placemark = placemarks![0] as CLPlacemark
                let addressDictionary = placemark.addressDictionary! as NSDictionary

                let str:NSMutableString = ""
                if let address = addressDictionary.objectForKey(kABPersonAddressStreetKey) as? String{
                    str.appendString(address)
                }

                if let state = addressDictionary.objectForKey(kABPersonAddressStateKey) as? String{
                    str.appendString(state)
                }

                if let city = addressDictionary.objectForKey(kABPersonAddressCityKey) as? String{
                    str.appendString(city)
                }

                info = str as String
            }
        }
        )
        return info
}

以下是警告

如果你能帮我修好它，我会很感激的:)

Answer 1

将import AddressBook替换为import Contacts，同时也替换

addressDictionary.objectForKey(kABPersonAddressStreetKey)与addressDictionary.objectForKey(CNPostalAddress.Street)

addressDictionary.objectForKey(kABPersonAddressStateKey)与addressDictionary.objectForKey(CNPostalAddress.State)

addressDictionary.objectForKey(kABPersonAddressCityKey)与addressDictionary.objectForKey(CNPostalAddress.City)

使用完成

func reverseGeocoder (completion: (info:String) -> Void){

    var geocoder = CLGeocoder()
    var currentUserLocation = CLLocation(latitude: 30, longitude: 122)
    geocoder.reverseGeocodeLocation(currentUserLocation, completionHandler: {
        (placemarks,error) -> Void in
        if placemarks != nil && placemarks?.count > 0{
            let placemark = placemarks![0] as CLPlacemark
            let addressDictionary = placemark.addressDictionary! as NSDictionary

            let str:NSMutableString = ""
            if let address = addressDictionary.objectForKey(kABPersonAddressStreetKey) as? String{
                str.appendString(address)
            }

            if let state = addressDictionary.objectForKey(kABPersonAddressStateKey) as? String{
                str.appendString(state)
            }

            if let city = addressDictionary.objectForKey(kABPersonAddressCityKey) as? String{
                str.appendString(city)
            }
            completion(info: str as String)

        }
    }
    )

因此，它似乎是iOS 9中的一个新类，您必须导入内容。

import Contacts

CNPostalAddress封装城市、街道、州等信息。这是更多的细节。班级/

Answer 3

if let coordinates = base.coOrdinates
        {
          if let lat = coordinates.lat {
            let location = CLLocation(latitude: lat, longitude: coordinates.lon!)
            let reverseGeocoder = CLGeocoder()
            reverseGeocoder.reverseGeocodeLocation(location, completionHandler: {place,_ in
              //print(place)
              let myPlacemark = place![0]
              let countryName = myPlacemark.country
              let cityName = myPlacemark.subAdministrativeArea
              let streetName = myPlacemark.subLocality
              NSOperationQueue.mainQueue().addOperationWithBlock {
                self.lastLocationLabel.text = "\(streetName!), \(cityName!), \(countryName!)"
              }
            })
          } else {
            self.lastLocationLabel.text = "Not available"
          }
        }

也许能帮到你。我就是这样从坐标中得到位置字符串的。
