SwiftUI - 导航栏颜色更改未应用于状态栏 [英] SwiftUI - Navigation bar colour change not being applied to status bar

问题描述

我有以下几点:

var body: some View {
        NavigationView {
            VStack {
                 Text("Hello")
            }.navigationBarTitle("Edit Profile", displayMode: .inline)
             .background(NavigationConfiguration { nc in
                 nc.navigationBar.barTintColor = .red
                 nc.navigationBar.titleTextAttributes = [.foregroundColor: UIColor.black]
            })
        }.navigationViewStyle(StackNavigationViewStyle())
}

对于导航栏的配置，我有:

For the configuration of the nav bar i have:

struct NavigationConfiguration: UIViewControllerRepresentable {
    var configuration: (UINavigationController) -> Void = { _ in }
    func makeUIViewController(context: UIViewControllerRepresentableContext<NavigationConfiguration>) -> UIViewController {
        UIViewController()
    }
    func updateUIViewController(_ uiViewController: UIViewController, context: UIViewControllerRepresentableContext<NavigationConfiguration>) {
        if let nc = uiViewController.navigationController {
            self.configuration(nc)
        }
    }
}

但由于某种原因，顶部状态栏被排除在外，并且没有对其应用颜色:

But for some reason the top status bar is being left out and the colour is not being applied to it:

如何将红色也应用到导航栏上方的状态栏，我希望它是相同的颜色.

How can the red colour also be applied to the status bar above the nav bar, I want it to be the same colour.

我尝试了以下方法，但失败了:

I've tried the below, but this fails:

init() {
    UINavigationBar.appearance().backgroundColor = .red
}

推荐答案

尝试以下操作(它应该可以工作，至少在 Xcode 11.4/iOS 13.4 上测试过，但有人报告它不是，所以它可能是依赖的)

Try the following (it should work, at least as tested with Xcode 11.4 / iOS 13.4, but someone reported it was not, so it might be dependent)

init() {
       let navBarAppearance = UINavigationBarAppearance()
       navBarAppearance.configureWithOpaqueBackground()
       navBarAppearance.backgroundColor = UIColor.systemRed

       UINavigationBar.appearance().standardAppearance = navBarAppearance
}
