打开第二个视图，如NavigationLink onRecive()

import SwiftUI

struct ContentView: View {
    @StateObject var viewModel = ViewModel()
    @State private var showSecondView = false
    
    var body: some View {
        NavigationView {
            VStack {
                Text("First View")
                    .font(.title)
                
                NavigationLink(
                    destination: SecondView(),
                    isActive: $showSecondView,
                    label: {
                        Text("Go to Second View")
                            .font(.headline)
                            .padding()
                            .background(Color.blue)
                            .foregroundColor(.white)
                            .cornerRadius(10)
                    })
                    .onReceive(viewModel.dataChanged) { _ in
                        // 执行一些操作，例如更新视图的状态
                        showSecondView = true
                    }
            }
            .padding()
        }
    }
}

struct SecondView: View {
    var body: some View {
        Text("Second View")
            .font(.title)
    }
}

class ViewModel: ObservableObject {
    @Published var dataChanged = false
    
    // 模拟数据变化
    func fetchData() {
        // 执行网络请求、处理数据等操作
        
        // 数据变化后设置dataChanged为true
        dataChanged = true
    }
}
