使用key:value from local JSON - SwiftUI更改按钮/标签文本

{
  "buttonText": "Click Me",
  "labelText": "Hello, World!"
}

struct DataModel: Codable {
  let buttonText: String
  let labelText: String
}

import SwiftUI

struct ContentView: View {
  @State private var data: DataModel? // 存储解析后的数据

  var body: some View {
    VStack {
      Button(action: {
        // 在按钮点击时更新文本内容
        if let buttonText = data?.buttonText {
          print(buttonText)
        }
      }) {
        Text("Button")
      }

      if let labelText = data?.labelText {
        // 使用标签显示文本内容
        Text(labelText)
      }
    }
    .onAppear {
      loadData() // 在视图加载时加载数据
    }
  }

  func loadData() {
    if let url = Bundle.main.url(forResource: "data", withExtension: "json") {
      do {
        let data = try Data(contentsOf: url)
        let decoder = JSONDecoder()
        self.data = try decoder.decode(DataModel.self, from: data)
      } catch {
        print("Error: \(error)")
      }
    }
  }
}
