ios - 在SwiftUI中将@EnvironmentObject与PresentationButton一起使用

我正试图通过@EnvironmentObject传递数据，但它仅在我通过NavigationButton转到下一个视图时才起作用，但是，我希望以模式（PresentationButton）呈现下一个视图

struct ContentView : View {

     @EnvironmentObject var settings: UserSettings

     var body: some View {
        NavigationView {
        VStack {
            // A button that writes to the environment settings
            Button(action: {
                self.settings.score += 1
            }) {
                Text("Increase Score")
            }
            NavigationButton(destination: DetailView()) {
                Text("Show Detail View")
            }
        }
      }
   }
}

struct DetailView: View {
     @EnvironmentObject var settings: UserSettings

     var body: some View {
     // A text view that reads from the environment settings
        VStack {
            Text("Score: \(settings.score)")
        }
     }
 }

我想用的是：

 PresentationButton( Text("Show Detail View"), destination: DetailView())

最佳答案

尝试使用DetailView将可绑定对象提供给environmentObject：

PresentationButton(Text("Show Detail View"),
                   destination: DetailView().environmentObject(settings))
