在纸上进行选择后不可刷新 我再次遇到了另一个愚蠢的错误。目前的问题是这个。我正在使用Apple的MklocalsearchCompleter获取餐厅的名称和地址。我也在使用Swift ...

地址视图

import SwiftUI
import MapKit
import SwiftData

struct AddressView: View {
    @State private var locationService = LocationService(completer: .init())
    @State private var search: String = ""
    @Binding var isPresentingLocationView: Bool
    @Bindable var review: Review
    
    var body: some View {
        NavigationStack {
            ZStack {
                LinearGradient(gradient: Gradient(colors: [Color(red: 0.9725490196078431, green: 0.9607843137254902, blue: 0.8627450980392157, opacity: 1), Color(red: 0.9137254901960784, green: 0.9254901960784314, blue: 0.8509803921568627, opacity: 1), Color(red: 0.9882352941176471, green: 0.7529411764705882, blue: 0.13333333333333333, opacity: 1), Color(red: 0.9450980392156862, green: 0.47058823529411764, blue: 0.08627450980392157, opacity: 1)]), startPoint: .top, endPoint: .bottom).ignoresSafeArea()
                
                    .navigationTitle("Add Location")
                
                VStack {
                    HStack {
                        Image(systemName: "magnifyingglass")
                        TextField("Search for a restaurant", text: $search)
                            .autocorrectionDisabled()
                    }
                    
                    Spacer()
                    
                    List {
                        ForEach(locationService.completions) { completion in
                            Button(action: {didTapOnCompletion(completion)}) {
                                VStack(alignment: .leading, spacing: 4) {
                                    Text(completion.title)
                                        .font(.headline)
                                        .fontDesign(.rounded)
                                    Text(completion.subTitle)
                                }
                            }
                            
                            .listRowBackground(Color.clear)
                        }
                    }
                    .listStyle(.plain)
                    .scrollContentBackground(.hidden)
                }
                .onChange(of: search) {
                    locationService.update(queryFragment: search)
                }
                .padding()

                .presentationBackground(.regularMaterial)
                .presentationBackgroundInteraction(.enabled(upThrough: .large))
            }
        }
    }
    private func didTapOnCompletion(_ completion: SearchCompletions) {
        isPresentingLocationView = false
        review.restaurantName = completion.title
        review.location = completion.subTitle
        print("this is the name \(review.restaurantName) and this is the location \(review.location)")

    }
}

我无法弄清楚发生了什么。这也是一些GIF。

您应该将review属性传递到地址视图，而不是创建并传递一个新实例Review
