iOS反向地理編碼（從座標獲取位置的名稱，而不僅僅是地址）

我正在爲自己構建一個小型應用程序，現在它有一個名爲performSearch的函數，可以在您的本地區域內執行搜索所有附近的咖啡店，健身房和餐館都會在這些位置放置針腳。但是，我很困惑我如何獲得註解以顯示實際地圖視圖中顯示的位置名稱。任何人有任何經驗？iOS反向地理編碼（從座標獲取位置的名稱，而不僅僅是地址）

基本上，而不是隻顯示地址，我想註釋說「星巴克地址......」

示例代碼：

這不會與任何給定的搜索字段搜索，並在降低引腳使用該搜索字段在給定區域中映射所有位置的視圖。

var matchingItems: [MKMapItem] = [MKMapItem]() 
@IBOutlet weak var map: MKMapView! 

func performSearch(searchField: String) { 

    matchingItems.removeAll() 

    //search request 
    let request = MKLocalSearchRequest() 
    request.naturalLanguageQuery = searchField 
    request.region = self.map.region 

    // process the request 
    let search = MKLocalSearch(request: request) 
    search.startWithCompletionHandler { response, error in 
     guard let response = response else { 
      print("There was an error searching for: \(request.naturalLanguageQuery) error: \(error)") 
      return 
     } 

     for item in response.mapItems { 
      // customize your annotations here, if you want 
      var annotation = item.placemark 
      self.reverseGeocoding(annotation.coordinate.latitude, longitude: allData.coordinate.longitude) 

      self.map.addAnnotation(annotation) 
      self.matchingItems.append(item) 
     } 

    } 
} 


func reverseGeocoding(latitude: CLLocationDegrees, longitude: CLLocationDegrees) { 
    let location = CLLocation(latitude: latitude, longitude: longitude) 
    CLGeocoder().reverseGeocodeLocation(location, completionHandler: {(placemarks, error) -> Void in 
     if error != nil { 
      print(error) 
      return 
     } 
     else if placemarks?.count > 0 { 
      let pm = placemarks![0] 
      let address = ABCreateStringWithAddressDictionary(pm.addressDictionary!, false) 
      print("\n\(address)") 
      if pm.areasOfInterest?.count > 0 { 
       let areaOfInterest = pm.areasOfInterest?[0] 
       print(areaOfInterest!) 
      } else { 
       print("No area of interest found.") 
      } 
     } 
    }) 
}

首先，reverseGeocodeLocation異步運行，所以你不得不使用完成處理模式。

但是，第二，反向地理編碼是不必要的，因爲response.mapItems中的item具有name屬性。因此，請將其用作註釋的標題。

例如：

func performSearch(searchField: String) { 
    matchingItems.removeAll() 

    //search request 
    let request = MKLocalSearchRequest() 
    request.naturalLanguageQuery = searchField 
    request.region = map.region 

    // process the request 
    let search = MKLocalSearch(request: request) 
    search.startWithCompletionHandler { response, error in 
     guard let response = response else { 
      print("There was an error searching for: \(request.naturalLanguageQuery) error: \(error)") 
      return 
     } 

     for item in response.mapItems { 
      let annotation = MKPointAnnotation() 
      annotation.title = item.name 
      annotation.subtitle = item.placemark.title 
      annotation.coordinate = item.placemark.coordinate 
      self.map.addAnnotation(annotation) 
      self.matchingItems.append(item) 
     } 
    } 
}
