SwiftuUI NavigationLink inside touchBar

问题

I'm trying to create NavigationLink in MacBook touchBar with help of SwiftUI. Actually with my piece of code, the button is shown in touchbar, but unfortunately the link doesn't work.

NavigationView {
  .touchBar {
    NavigationLink(destination: BookView()) {
      Text("GoToBook")
    }
  }
}

struct BookView: View {
  var body: some View {
    Text("Hello")
  }
}

回答1:

Try instead with Button in touchBar activating NavigationLink programmatically, like below

@State private var isActive = false

...

// below in body
NavigationView {
  SomeView()      // << your view here 
  .background(NavigationLink(destination: BookView(), isActive: $isActive) { 
                EmptyView() 
              }  // hidden link
  )
  .touchBar {
     Button("GoToBook") { self.isActive.toggle() } // activate link
  }
}
