更改导航按钮 SwiftUI 的颜色

Question

如何将导航“后退按钮”（它是自动创建的）的颜色更改为黑色， 以及 DisclosureGroup “Chevron” 的颜色为另一种颜色？

我尝试过 .buttonStyle(PlainButtonStyle()) 和 .foregroundColor(.black)

struct ContentView: View {

    var body: some View {
    
        NavigationView {
            NavigationLink(destination: DetailView()) {
        
                Text("Go to details ->")
                    .foregroundColor(.purple)
                    .underline()
            }
        }
    }
}


struct DetailView: View {
    @State private var isExpanded = false
    
    var body: some View {
        VStack {
            DisclosureGroup("All Details", isExpanded: $isExpanded) {
                
            }.buttonStyle(PlainButtonStyle())
            .foregroundColor(.black)

            Spacer()
        }
        .padding()
    }
}

Answer 1

在这种情况下使用.accentColor

        DisclosureGroup("All Details", isExpanded: $isExpanded) {
            
        }
        .accentColor(.black)

添加

struct ContentView: View {

    var body: some View {
    
        NavigationView {
            NavigationLink(destination: DetailView()) {
        
                Text("Go to details ->")
                    .foregroundColor(.purple)
                    .underline()
            }
        }.accentColor(.black)
    }
}
