我如何在孩子们的视图中启动Swiftui应用程序？

好吧，这就是我的应用程序的样子。

@main
struct MemorizableApp: App {
    init() {
        FirebaseApp.configure()                             // Configure the FirebaseApp instance
        Database.database().isPersistenceEnabled = true     // Set DB persistence to true
    }
    
    var body: some Scene {
        WindowGroup {
            if Auth.auth().currentUser == nil {
                SignInView()
                    .onOpenURL{ url in
                        GIDSignIn.sharedInstance.handle(url)
                    }
            } else {
                MainView()
            }
        }
    }
}

这是MemorizableApp.swift。如您所见，该应用在MainView中启动。但是我希望该应用程序可以在笔记本视图中启动。显然，在上面的代码中将Mainview更改为NotebookSview不起作用，因为1）NotebookSview中没有NavigationView，而2）我将无法导航回MainView。但是，某种程度上，Apple的快捷方式应用程序完全可以做到这一点，而无需创建自定义的返回按钮。我该如何实现这种行为？

Okay, here's what my app looks like.

@main
struct MemorizableApp: App {
    init() {
        FirebaseApp.configure()                             // Configure the FirebaseApp instance
        Database.database().isPersistenceEnabled = true     // Set DB persistence to true
    }
    
    var body: some Scene {
        WindowGroup {
            if Auth.auth().currentUser == nil {
                SignInView()
                    .onOpenURL{ url in
                        GIDSignIn.sharedInstance.handle(url)
                    }
            } else {
                MainView()
            }
        }
    }
}

And this is MemorizableApp.swift. As you can see, the app starts in MainView. But I want the app to launch in NotebooksView instead. Obviously, changing MainView to NotebooksView in the code above won't work because 1) NotebooksView doesn't have a NavigationView in it, and 2) I won't be able to navigate back to MainView. But somehow Apple's Shortcuts app did exactly this without creating a custom back button. How can I achieve this behaviour?

您需要做的是以编程方式激活navigationLink：

in mainView add：@State var showerNavigate = false，然后修改navigationlink到以下内容：

NavigationLink(destination: NoteBooksView(), isActive: $shouldNavigate) {
    ...
}

和MemorizableApp：

@main
struct MemorizableApp: App {
    init() {
        FirebaseApp.configure()                             // Configure the FirebaseApp instance
        Database.database().isPersistenceEnabled = true     // Set DB persistence to true
    }
    var body: some Scene {
        WindowGroup {
            if Auth.auth().currentUser == nil {
                SignInView()
                    .onOpenURL{ url in
                        GIDSignIn.sharedInstance.handle(url)
                    }
            } else {
                MainView(shouldNavigate: true) //set it to true
            }
        }
    }
}

注意：navigationLink的使用（目标：content：content，isActive：iSACTIVE：绑定＆lt; bool＆gt;）＆amp; navigationView是 ios 16中的debected 。看看在这里＆amp; 在这里。

What you need to do is activate your NavigationLink programmatically:

In MainView add: @State var shouldNavigate = false, then modify your NavigationLink to the following:

NavigationLink(destination: NoteBooksView(), isActive: $shouldNavigate) {
    ...
}

And in MemorizableApp:

@main
struct MemorizableApp: App {
    init() {
        FirebaseApp.configure()                             // Configure the FirebaseApp instance
        Database.database().isPersistenceEnabled = true     // Set DB persistence to true
    }
    var body: some Scene {
        WindowGroup {
            if Auth.auth().currentUser == nil {
                SignInView()
                    .onOpenURL{ url in
                        GIDSignIn.sharedInstance.handle(url)
                    }
            } else {
                MainView(shouldNavigate: true) //set it to true
            }
        }
    }
}

Note: The use of NavigationLink(destination: Content, isActive: Binding<Bool>) & NavigationView is deprecated in iOS 16. Take a look here & here.
