SwiftUI 更新导航栏标题颜色

如何在 SwiftUI 中更改导航栏标题颜色

NavigationView {
    List {
        ForEach(0..<15) { item in
            HStack {
                Text("Apple")
                    .font(.headline)
                    .fontWeight(.medium)
                    .color(.orange)
                    .lineLimit(1)
                    .multilineTextAlignment(.center)
                    .padding(.leading)
                    .frame(width: 125, height: nil)
                
                Text("Apple Infinite Loop. Address: One Infinite Loop Cupertino, CA 95014 (408) 606-5775 ")
                    .font(.subheadline)
                    .fontWeight(.regular)
                    .multilineTextAlignment(.leading)
                    .lineLimit(nil)
            }
        }
    }
    .navigationBarTitle(Text("TEST")).navigationBarHidden(false).foregroundColor(.orange)
}

我尝试过.foregroundColor(.orange)但它不起作用

也尝试过.navigationBarTitle(Text("TEST").color(.orange))

It is not需要使用.appearance()在全球范围内做到这一点。

尽管 SwiftUI 不直接公开导航样式，但您可以使用以下方法解决此问题UIViewControllerRepresentable。由于 SwiftUI 使用常规UINavigationController在幕后，视图控制器仍然有一个有效的.navigationController财产。

struct NavigationConfigurator: UIViewControllerRepresentable {
    var configure: (UINavigationController) -> Void = { _ in }

    func makeUIViewController(context: UIViewControllerRepresentableContext<NavigationConfigurator>) -> UIViewController {
        UIViewController()
    }
    func updateUIViewController(_ uiViewController: UIViewController, context: UIViewControllerRepresentableContext<NavigationConfigurator>) {
        if let nc = uiViewController.navigationController {
            self.configure(nc)
        }
    }

}

并使用它

struct ContentView: View {
    var body: some View {
        NavigationView {
            ScrollView {
                Text("Don't use .appearance()!")
            }
            .navigationBarTitle("Try it!", displayMode: .inline)
            .background(NavigationConfigurator { nc in
                nc.navigationBar.barTintColor = .blue
                nc.navigationBar.titleTextAttributes = [.foregroundColor : UIColor.white]
            })
        }
    .navigationViewStyle(StackNavigationViewStyle())
    }
}
