如何在SwiftUI中对阵列使用UserDefault

import SwiftUI

class ArrayManager: ObservableObject {
    @Published var array: [String] {
        didSet {
            UserDefaults.standard.set(array, forKey: "array")
        }
    }
    
    init() {
        self.array = UserDefaults.standard.stringArray(forKey: "array") ?? []
    }
}

import SwiftUI

struct ContentView: View {
    @EnvironmentObject var arrayManager: ArrayManager
    
    var body: some View {
        VStack {
            // 在视图中使用阵列数据
            ForEach(arrayManager.array, id: \.self) { item in
                Text(item)
            }
            
            // 修改阵列数据
            Button(action: {
                arrayManager.array.append("New Item")
            }) {
                Text("Add Item")
            }
        }
    }
}

import SwiftUI

@main
struct MyApp: App {
    @StateObject var arrayManager = ArrayManager()
    
    var body: some Scene {
        WindowGroup {
            ContentView()
                .environmentObject(arrayManager)
        }
    }
}
