SwiftUI在NavigationLink中更改后退按钮的颜色

struct ContentView: View {
    var body: some View {
        NavigationView {
            VStack {
                NavigationLink(destination: DetailView()) {
                    Text("Go to Detail")
                }
            }
            .navigationBarTitle("Main")
            .navigationBarItems(leading: backButton)
        }
    }
    
    var backButton: some View {
        Button(action: {
            // 处理后退按钮点击事件
        }) {
            Image(systemName: "arrow.left")
                .foregroundColor(.red) // 设置按钮颜色
        }
    }
}

struct DetailView: View {
    var body: some View {
        Text("Detail View")
            .navigationBarTitle("Detail")
    }
}
