SwiftUI how to set image for NavigationBar titleView like in UIKit?

问题

I want to set an image in the titleView of NavigationBar in SwiftUI, as we do in UIKit

navigationItem.titleView = UIImageView(image: UIImage(named: "logo"))

this is how we do it in UIKit.

anyone know how to do it?

Here's how to do it:

1. Add SwiftUIX to your project.
2. Set your custom title view via View.navigationBarTitleView(_:displayMode:)

Example code:

struct ContentView: View {
    public var body: some View {
        NavigationView {
            Text("Hello World")
                .navigationBarTitleView(MyView())
        }
    }
}

Simple, Just add your root view into ZStack with top alignment and add your custom center view after root view

struct CenterNavigattionBar: View {
    var body: some View {
        ZStack(alignment: .top){
            //Root view with empty Title
            NavigationView {
                Text("Test Navigation")
                .navigationBarTitle("",displayMode: .inline)
                .navigationBarItems(leading: Text("Cancle"), trailing: Text("Done"))
            }
            //Your Custom Title
            VStack{
                Text("add title and")
                    .font(.headline)
                Text("subtitle here")
                    .font(.subheadline)
            }
        }

    }
}

Before Image

After Image

Currently, you can't.

There are two overloads for .navigationBarTitle(), taking either a Text view or a type conforming to StringProtocol. You can't even pass in a modified view like Text("Title").font(.body). This would be a great feature, I'd submit a feature request: http://feedbackassistant.apple.com
