关闭最后一个窗口时关闭SwiftUI应用程序
是否可以在用户关闭最后一个窗口时关闭 macOS SwiftUI 应用程序,类似于applicationShouldTerminateAfterLastWindowClosedAppDelegate 函数。
func applicationShouldTerminateAfterLastWindowClosed(NSApplication) -> Bool
回答
我在这里找到了答案 https://www.hackingwithswift.com/quick-start/swiftui/how-to-add-an-appdelegate-to-a-swiftui-app
为 AppDelegate 创建一个类
import Foundation
import AppKit
class AppDelegate: NSObject, NSApplicationDelegate {
func applicationShouldTerminateAfterLastWindowClosed(_ sender: NSApplication) -> Bool {
return true
}
}
向 SwiftUI App 类添加属性包装器
import SwiftUI
@main
struct SwiftUIApp: App {
@NSApplicationDelegateAdaptor(AppDelegate.self) var appDelegate
var body: some Scene {
WindowGroup {
ContentView()
.frame(minWidth: 300, idealWidth: 300, maxWidth: .infinity, minHeight: 300, idealHeight: 300, maxHeight: .infinity)
}
}
}
