Dynamischer Code zum Speichern mehrerer Werte

Question

Ich habe ein Polygon, das für eine Grafschaft mit Google Maps iOS SDK geplottet wurde.

Für jeden Landkreis gibt es mehrere Breiten- und Längengrade, so dass wir ihn grafisch darstellen können.

Der Code ist für 1 Land. Gibt es einen Weg, wo ich es für mehrere Länder schaffen kann?

So würde die Struktur sein:

County 1 - 

lat  long 
32.4757 -86.41182 
31.7557 -88.41482 
32.4357 -87.65335 

County 2 - 

lat  long 
42.4757 -96.41182 
41.7557 -98.41482 
42.4357 -97.65335 

County 3 - 

lat  long 
52.4757 -76.41182 
51.7557 -78.41482 
52.4357 -77.65335 

Code:

import UIKit 
import GoogleMaps 

class ViewController: UIViewController { 

override func loadView() { 
    let camera = GMSCameraPosition.cameraWithLatitude(37.0902, longitude: -95.7129, zoom: 3.0) 
    let mapView = GMSMapView.mapWithFrame(CGRect.zero, camera: camera) 
    mapView.myLocationEnabled = true 
    view = mapView 


    struct county { 
     let lat: CLLocationDegrees 
     let long: CLLocationDegrees 
    } 

    let counties = [

Answer 1

Option 1

Sie mögen versuchen, diese können auf Location Struktur erstellen, die lat lange speichern und Ändern Sie das Land struct, das den Ländernamen und das CountryLocation-Array speichert.

Jetzt erstellen Array von Land und alle Objekte davon speichert Standorte für dieses bestimmte Land.

Option 2

können Sie Dictionary verwenden, die Sie nur für diesen Schlüssel als Ländername und Wert als Array Ihres Landes enthalten das Wörterbuch keine Notwendigkeit zu schaffen, müssen irgend etwas in Ihrem struct zu ändern.

var countries = [String: [Country]]() 

Edit: speichern Objekt für Option 1 Versuch wie diese.

var countries = [Country(name:"Ind",locations:[CountryLocation(lat:22.663696,long:87.746803),CountryLocation(lat:22.542061,long:88.318954)], 
       Country(name:"UK",locations:[CountryLocation(lat:52.412811,long:-1.778197),CountryLocation(lat:51.481583,long:-3.179090),CountryLocation(lat:50.768036,long:0.290472)] 
       ]
