在Mac催化剂上打开一个新窗口
我正在移植一个iPad应用程序使用Mac催化剂。我正在尝试打开一个视图控制器在一个新的窗口。
如果我使用的是严格的AppKit，我可以像这个帖子中描述的那样做一些事情。但是，由于我使用的是UIKit，所以没有可用的showWindow()方法。
这篇文章说，通过在项目中的一个新包中添加AppKit是可能的(我这样做了)，但是它并没有解释如何实际显示新窗口的具体细节。上面写着..。
另一件您不能做的事情是生成一个具有UIKit视图层次结构的新的UIKit。但是，您的UIKit代码能够生成一个新的窗口场景，您的AppKit代码能够获取它所呈现的结果NSWindow，并劫持它来执行您想要的任何操作，因此在这个意义上，您可以为辅助调色板和各种其他功能生成UIKit窗口。
有人知道如何实现本文中所解释的内容吗？
TL;DR:，我如何用Mac催化剂作为一个新的独立NSWindow打开一个UIViewController？

编辑:添加了关于如何拥有其他不同窗口(如面板)的信息
为了在mac上支持多个窗口，您所需要做的就是在iPad上支持多个窗口。
您可以在从22:28分钟开始的这 WWDC会话中找到所需的所有信息，但是要总结它，您需要做的是支持新的场景生命周期模型。
首先编辑目标并检查支持多窗口复选标记。
完成此操作后，单击配置选项，该选项将带您到info.plist。确保您有合适的应用场景报表条目
创建一个名为SceneDelegate.swift的新的快速文件，并将下面的样板代码粘贴到其中
import UIKit
class SceneDelegate: UIResponder, UIWindowSceneDelegate {
var window: UIWindow?
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
// Use this method to optionally configure and attach the UIWindow `window` to the provided UIWindowScene `scene`.
// If using a storyboard, the `window` property will automatically be initialized and attached to the scene.
// This delegate does not imply the connecting scene or session are new (see `application:configurationForConnectingSceneSession` instead).
// Create the SwiftUI view that provides the window contents.
guard let _ = (scene as? UIWindowScene) else { return }
}
func sceneDidDisconnect(_ scene: UIScene) {
// Called as the scene is being released by the system.
// This occurs shortly after the scene enters the background, or when its session is discarded.
// Release any resources associated with this scene that can be re-created the next time the scene connects.
// The scene may re-connect later, as its session was not neccessarily discarded (see `application:didDiscardSceneSessions` instead).
}
func sceneDidBecomeActive(_ scene: UIScene) {
// Called when the scene has moved from an inactive state to an active state.
// Use this method to restart any tasks that were paused (or not yet started) when the scene was inactive.
}
func sceneWillResignActive(_ scene: UIScene) {
// Called when the scene will move from an active state to an inactive state.
// This may occur due to temporary interruptions (ex. an incoming phone call).
}
func sceneWillEnterForeground(_ scene: UIScene) {
// Called as the scene transitions from the background to the foreground.
// Use this method to undo the changes made on entering the background.
}
func sceneDidEnterBackground(_ scene: UIScene) {
// Called as the scene transitions from the foreground to the background.
// Use this method to save data, release shared resources, and store enough scene-specific state information
// to restore the scene back to its current state.
}
}你基本上就完蛋了。运行你的应用程序，点击命令+N创建任意数量的新窗口。
如果要在代码中创建新窗口，可以使用以下命令：
@IBAction func newWindow(_ sender: Any) {
UIApplication.shared.requestSceneSessionActivation(nil, userActivity: nil, options: nil) { (error) in
//
}
}，现在我们进入了如何创建额外的windows的大谜团。
关键是在应用程序中创建多个场景类型。您可以在info.plist (我无法正常工作)或在AppDelegate中完成。
让我们将函数更改为创建一个新窗口：
@IBAction func newWindow(_ sender: Any) {
var activity = NSUserActivity(activityType: "panel")
UIApplication.shared.requestSceneSessionActivation(nil, userActivity: activity, options: nil) { (error) in
}
}为您的新场景创建一个新的故事板，创建至少一个视图控制器，并确保设置为故事板中的initalviewcontroller。
让我们将以下函数添加到app委托中：
func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
if options.userActivities.first?.activityType == "panel" {
let configuration = UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
configuration.delegateClass = CustomSceneDelegate.self
configuration.storyboard = UIStoryboard(name: "CustomScene", bundle: Bundle.main)
return configuration
} else {
let configuration = UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
configuration.delegateClass = SceneDelegate.self
configuration.storyboard = UIStoryboard(name: "Main", bundle: Bundle.main)
return configuration
}
}通过在请求场景时设置userActivity，我们可以知道要创建哪个场景并相应地为其创建配置。菜单中的新窗口或CMD+N仍然会创建默认的新窗口，但是新窗口按钮现在将从新的故事板创建UI。

有了SwiftUI，您就可以这样做了(感谢罗恩·塞布罗)：
1.激活多窗口支持：
2.要求新的场景：
struct ContentView: View {
var body: some View {
VStack {
// Open window type 1
Button(action: {
UIApplication.shared.requestSceneSessionActivation(nil,
userActivity: NSUserActivity(activityType: "window1"),
options: nil,
errorHandler: nil)
}) {
Text("Open new window - Type 1")
}
// Open window type 2
Button(action: {
UIApplication.shared.requestSceneSessionActivation(nil,
userActivity: NSUserActivity(activityType: "window2"),
options: nil,
errorHandler: nil)
}) {
Text("Open new window - Type 2")
}
}
}
}3.创建新的窗口视图：
struct Window1: View {
var body: some View {
Text("Window1")
}
}struct Window2: View {
var body: some View {
Text("Window2")
}
}4.更改SceneDelegate.swift：
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
if let windowScene = scene as? UIWindowScene {
let window = UIWindow(windowScene: windowScene)
if connectionOptions.userActivities.first?.activityType == "window1" {
window.rootViewController = UIHostingController(rootView: Window1())
} else if connectionOptions.userActivities.first?.activityType == "window2" {
window.rootViewController = UIHostingController(rootView: Window2())
} else {
window.rootViewController = UIHostingController(rootView: ContentView())
}
self.window = window
window.makeKeyAndVisible()
}
