在 SwiftUI 2.0 中添加 EnvironmentObject [英] Add EnvironmentObject in SwiftUI 2.0

问题描述

由于 SwiftUI 2.0 没有 AppDelegate 和 SceneDelegate，EnvironmentObjects 应该在哪里设置?

Since SwiftUI 2.0 does not have an AppDelegate and SceneDelegate anymore, where should EnvironmentObjects be set?

这是以前的做法，我现在必须在哪里添加它们?

This how it was done previously, where do i have to add them now?

window.rootViewController = UIHostingController(rootView: ContentView()
                             .environmentObject(settings))

推荐答案

尝试以下操作:

@main
struct TestApp: App {
    @StateObject var settings: Settings = ... // init here

    var body: some Scene {
        WindowGroup {
            ContentView()
                .environmentObject(settings)
        }
    }
}
