在iOS swiftui视图中实现前向地理编码功能

import SwiftUI
import CoreLocation

struct ContentView: View {
    @State private var address = ""
    @State private var coordinates = CLLocationCoordinate2D()
    
    var body: some View {
        VStack {
            TextField("输入地址", text: $address)
                .padding()
            
            Button("地理编码") {
                geocodeAddress()
            }
            .padding()
            
            Text("经度: \(coordinates.latitude), 纬度: \(coordinates.longitude)")
                .padding()
        }
    }
    
    func geocodeAddress() {
        let geocoder = CLGeocoder()
        
        geocoder.geocodeAddressString(address) { (placemarks, error) in
            if let error = error {
                print("地理编码失败: \(error.localizedDescription)")
                return
            }
            
            if let placemark = placemarks?.first {
                coordinates = placemark.location?.coordinate ?? CLLocationCoordinate2D()
            }
        }
    }
}
