如何在SwiftUI中从登录视图转换为tabView

import SwiftUI

struct LoginView: View {
    @State private var isLoggedIn = false
    
    var body: some View {
        NavigationView {
            VStack {
                // 登录表单
                // ...
                
                // 登录按钮
                Button(action: {
                    // 登录验证逻辑
                    isLoggedIn = true
                }) {
                    Text("登录")
                }
                
                // 跳转到TabView
                NavigationLink(
                    destination: TabView(),
                    isActive: $isLoggedIn,
                    label: {
                        EmptyView()
                    })
                    .hidden()
            }
        }
    }
}

struct TabView: View {
    var body: some View {
        TabView {
            // Tab 1
            Text("Tab 1")
                .tabItem {
                    Image(systemName: "1.circle")
                    Text("Tab 1")
                }
            
            // Tab 2
            Text("Tab 2")
                .tabItem {
                    Image(systemName: "2.circle")
                    Text("Tab 2")
                }
            
            // Tab 3
            Text("Tab 3")
                .tabItem {
                    Image(systemName: "3.circle")
                    Text("Tab 3")
                }
        }
    }
}
