从AppKit打开SwiftUI设置

发布于12月07日

在MacOS 14上，打开设置的方式已经改变.到目前为止，我一直使用的代码是:

if #available(macOS 13, *) {
    NSApp.sendAction(Selector(("showSettingsWindow:")), to: nil, from: nil)
} else {
    NSApp.sendAction(Selector(("showPreferencesWindow:")), to: nil, from: nil)
}

在MacOS 14上，此代码抛出错误消息Please use SettingsLink for opening the Settings scene.

实际问题:如何在MacOS 14(Sonoma)中以编程方式从AppKit打开应用程序设置

推荐答案

这是一种新方法:

@main
struct MyApp: App {

var body: some Scene {
    WindowGroup {
        RootScreen()
    }

    Settings {
        SettingsScreen()
    }

    MenuBarExtra("My App", systemImage: "mic.fill") {
        SettingsLink {
           Text("Settings")
        }
    }
    .keyboardShortcut(".", modifiers: .command)
}

Alternative if you have `NSMenu`

import SettingsAccess

private func setupStatusBar() {
    let menu = NSMenu()
    menu.addItem(NSMenuItem(title: "Settings", action: #selector(openSettings), keyEquivalent: ""))

    statusBarItem = NSStatusBar.system.statusItem(withLength: CGFloat(NSStatusItem.variableLength))
    statusBarItem!.menu = menu
    statusBarItem!.button?.image = NSImage(systemSymbolName: "mic.fill", accessibilityDescription: nil)
}

@objc private func openSettings() {
    if #available(macOS 14, *) {
        appState?.openSettingsSignal.send()
    }
}

import SettingsAccess

@main
struct MyApp: App {

    var body: some Scene {
        WindowGroup {
            RootScreen()
                .openSettingsAccess()
        }
    }
}

struct RootScreen: View {

    private let appState: AppState
    @Environment(\.openSettings) var openSettings

    var body: some View {
    }
    .onReceive(appState.openSettingsSignal) {
        try? openSettings()
    }
}

struct AppState {
    let openSettingsSignal = PassthroughSubject<Void, Never>()
}
