【问题标题】:Not able to get subLocality using CLPlacemark in swift无法在 swift 中使用 CLPlacemark 获取 subLocality
【发布时间】:2019-04-12 14:20:10
【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。

【解决方案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
    }
})

    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)")
                }
    
         })
