在tvOS中实现SwiftUI的主结构和明细结构

import SwiftUI

struct MainView: View {
    var body: some View {
        NavigationView {
            VStack {
                Text("主结构视图")
                    .font(.largeTitle)
                    .padding()
                
                NavigationLink(destination: DetailView()) {
                    Text("进入明细结构")
                        .font(.title)
                        .padding()
                }
            }
        }
    }
}

import SwiftUI

struct DetailView: View {
    var body: some View {
        VStack {
            Text("明细结构视图")
                .font(.largeTitle)
                .padding()
            
            Button(action: {
                // 执行操作
            }) {
                Text("返回主结构")
                    .font(.title)
                    .padding()
            }
        }
    }
}
