问题描述

目前，我找不到任何方法来更改SwiftUI中导航栏的颜色/背景.有提示吗?

Currently I couldn't find any method to change the color/background of the navigation bar in SwiftUI. Any tips?

推荐答案

在SwiftUI中，目前我们不能直接对其进行更改，但是您可以像这样更改NavigationBar的外观，

In SwiftUI, at this point we can not change it directly, but you can change navigationBar appearance like this,

struct YourView: View {
    init() {
        UINavigationBar.appearance().backgroundColor = .orange

        //Use this if NavigationBarTitle is with Large Font
        UINavigationBar.appearance().largeTitleTextAttributes = [.font : UIFont(name: "Georgia-Bold", size: 20)!]

        //Use this if NavigationBarTitle is with displayMode = .inline
        //UINavigationBar.appearance().titleTextAttributes = [.font : UIFont(name: "Georgia-Bold", size: 20)!]
    }

    var body: some View {
        NavigationView {
            Text("Hello World!")
              .navigationBarTitle(Text("Dashboard").font(.subheadline), displayMode: .large)
            //.navigationBarTitle (Text("Dashboard"), displayMode: .inline)
        }
    }
}

我希望这会对您有所帮助.谢谢！
