使用viewcontroller时的swiftUI导航栏标题设置

import SwiftUI

struct ContentView: View {
    var body: some View {
        NavigationView {
            Text("Hello, World!")
                .navigationBarTitle("标题")
        }
    }
}

override func viewDidLoad() {
    super.viewDidLoad()
    
    let contentView = ContentView()
    let hostingController = UIHostingController(rootView: contentView)
    
    addChild(hostingController)
    view.addSubview(hostingController.view)
    hostingController.view.frame = view.bounds
    hostingController.didMove(toParent: self)
}
