将GPS坐标转换为Swift中的城市名称/地址

Question

我有一个经度/纬度位置，我想将其转换为Swift中的位置名称String。做这个的最好方式是什么？我相信最好使用reverseGeocodeLocation函数，但不完全确定如何。这是我到目前为止有：

func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) { 
    if (locationFixAchieved == false) { 
     locationFixAchieved = true 
     var locationArray = locations as NSArray 
     var locationObj = locationArray.lastObject as CLLocation 
     var coord = locationObj.coordinate 
     var latitude = coord.latitude 
     var longitude = coord.longitude 

     getCurrentWeatherData("\(longitude)", latitude: "\(latitude)") 
     reverseGeocodeLocation(location:coord, completionHandler: { (<#[AnyObject]!#>, <#NSError!#>) -> Void in 
      <#code#> 
     }) 

    } 
} 

func reverseGeocodeLocation(location: CLLocation!, completionHandler: CLGeocodeCompletionHandler!){ 

} 

Answer 1

你需要编写的代码是这样的：

geocoder.reverseGeocodeLocation(currentLocation, completionHandler: { 
      placemarks, error in 

       if error == nil && placemarks.count > 0 { 
        self.placeMark = placemarks.last as? CLPlacemark 
        self.adressLabel.text = "\(self.placeMark!.thoroughfare)\n\(self.placeMark!.postalCode) \(self.placeMark!.locality)\n\(self.placeMark!.country)" 
        self.manager.stopUpdatingLocation() 
       } 
      }) 

Answer 2

请查看这个答案。

func getAddressFromGeocodeCoordinate(coordinate: CLLocationCoordinate2D) { 
    let geocoder = GMSGeocoder() 
    geocoder.reverseGeocodeCoordinate(coordinate) { response , error in 

     //Add this line 
     if let address = response!.firstResult() { 
     let lines = address.lines! as [String] 
     print(lines) 

     } 
    } 
    } 

Answer 3

斯威夫特代码来获得地址的标的，很好地格式化

let address = ABCreateStringWithAddressDictionary(placemark.addressDictionary!, false).componentsSeparatedByString("\n").joinWithSeparator(", ") 

print(address!) 

Answer 4

我使用的斯威夫特3/XCode的8

我用Benjamin Herzog's answer但我遇到了一些相关的构建错误到可选和铸造。

在重写它时，我决定将它封装在一个函数中并进行概括，以便它可以很容易地插入到任何地方。

import CoreLocation 

func getPlacemark(forLocation location: CLLocation, completionHandler: @escaping (CLPlacemark?, String?) ->()) { 
    let geocoder = CLGeocoder() 

    geocoder.reverseGeocodeLocation(location, completionHandler: { 
     placemarks, error in 

     if let err = error { 
      completionHandler(nil, err.localizedDescription) 
     } else if let placemarkArray = placemarks { 
      if let placemark = placemarkArray.first { 
       completionHandler(placemark, nil) 
      } else { 
       completionHandler(nil, "Placemark was nil") 
      } 
     } else { 
      completionHandler(nil, "Unknown error") 
     } 
    }) 

} 

使用它：

getPlacemark(forLocation: originLocation) { 
    (originPlacemark, error) in 
     if let err = error { 
      print(err) 
     } else if let placemark = originPlacemark { 
      // Do something with the placemark 
     } 
    }) 
}
