SwiftUI 2:在新窗口中打开视图的方式 [英] SwiftUI 2: the way to open view in new window

问题描述

假设我有一个应用程序

var storeVM = BookStoreViewModel(bla1: bla1, bla2: bla2, bla3: bla3)@SceneBuilder var body:一些场景{窗口组{BookStoreView(型号:storeVM)}#if 操作系统(macOS)设置{设置视图(模型:配置)}#万一}

BookStore 有一个 Grid，其中有很多书保存在某个 DB 中.

BookView 可以通过以下方式启动:

BookView(model: bookViewModel)

目标:在新的独立窗口中打开 BookView(例如单击按钮).我该怎么做?

---

奖金问题:如何从代码中打开 SettingsView(model: config)?

---

PS:NavigationLink 不是我的解决方案，因为我没有使用 NavigationView.

解决方案

我找到了这个答案，它在能够打开新窗口方面对我有用:

Lets imagine that I have an App

var storeVM = BookStoreViewModel(bla1: bla1, bla2: bla2, bla3: bla3)

@SceneBuilder var body: some Scene {
    WindowGroup {
        BookStoreView( model: storeVM )
    }
    
    #if os(macOS)
    Settings {
        SettingsView(model: config)
    }   
    #endif
}

BookStore have a Grid with a lot of books saved in some DB.

BookView can be initiated by a following way:

BookView(model: bookViewModel)

Target: to open BookView IN A NEW SEPARATED WINDOW(as example by click on the button). How can I do this?

---

Bonus question: How can I open SettingsView(model: config) from the code?

---

PS: NavigationLink is not solution for me because I not using the NavigationView.

解决方案

I found this answer, which worked for me in terms of being able to open a new window: https://developer.apple.com/forums/thread/651592?answerId=651132022#651132022

I'm on xcode 12.3, Swift 5.3, running Big Sur.

The following is an example of how to set things up so a button in the ContentView can be used to open the OtherView window.

@main
struct testApp: App {
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
        WindowGroup("OtherView") {
            OtherView()
        }
        .handlesExternalEvents(matching: Set(arrayLiteral: "*"))
    }
}

struct ContentView: View {
    @Environment(.openURL) var openURL

    var body: some View {
       Button("Other View") {
           if let url = URL(string: "test://otherview") {
               openURL(url)
           }
       }
    }
}

struct OtherView: View {
    var body: some View {
        Text("Other View!")
    }
}

Note: Make sure to follow the URL Scheme instructions included in the linked answer (quoted here for convenience):

Now in Project->Info->URL Types type in test in the URL Schemes field (and the identifier field too) to register our app with the system.

I achieved this by editing the Info.plist file and making the additions there, i.e URL types -> URL Schemes...:
