设置
我有以下代码：(可以复制粘贴到新的macOS项目(
import Cocoa
import SwiftUI
@NSApplicationMain
class AppDelegate: NSObject, NSApplicationDelegate {
var statusBarItem: NSStatusItem!
func applicationDidFinishLaunching(_ aNotification: Notification) {
let statusBar = NSStatusBar.system
statusBarItem = statusBar.statusItem(
withLength: NSStatusItem.squareLength)
statusBarItem.button?.title = "🍎"
// Setting action
statusBarItem.button?.action = #selector(self.statusBarButtonClicked(sender:))
statusBarItem.button?.sendAction(on: [.leftMouseUp])
let statusBarMenu = NSMenu(title: "Status Bar Menu")
statusBarMenu.addItem(
withTitle: "Order an apple",
action: #selector(AppDelegate.orderAnApple),
keyEquivalent: "")
statusBarMenu.addItem(
withTitle: "Cancel apple order",
action: #selector(AppDelegate.cancelAppleOrder),
keyEquivalent: "")
// Setting menu
statusBarItem.menu = statusBarMenu
}
@objc func statusBarButtonClicked(sender: NSStatusBarButton) {
let event = NSApp.currentEvent!
if event.type == NSEvent.EventType.rightMouseUp {
print("Right click!")
} else {
print("Left click!")
}
}
@objc func orderAnApple() {
print("Ordering a apple!")
}
@objc func cancelAppleOrder() {
print("Canceling your order :(")
}
}
实际行为：菜单在左键和右键单击时打开，状态栏按钮单击未触发。
删除此行后：
statusBarItem.menu = statusBarMenu
状态栏按钮单击左键时触发，菜单未显示(按预期(
所需行为：右键单击时菜单打开，左键单击菜单未打开，操作已触发。
我如何实现它？
编辑
在评论的帮助下，我设法实现了@red_menace行为：
import Cocoa
import SwiftUI
@NSApplicationMain
class AppDelegate: NSObject, NSApplicationDelegate {
var statusBarItem: NSStatusItem!
var menu: NSMenu!
func applicationDidFinishLaunching(_ aNotification: Notification) {
let statusBar = NSStatusBar.system
statusBarItem = statusBar.statusItem(
withLength: NSStatusItem.squareLength)
statusBarItem.button?.title = "🍎"
// Setting action
statusBarItem.button?.action = #selector(self.statusBarButtonClicked(sender:))
statusBarItem.button?.sendAction(on: [.leftMouseUp, .rightMouseUp])
let statusBarMenu = NSMenu(title: "Status Bar Menu")
statusBarMenu.addItem(
withTitle: "Order an apple",
action: #selector(AppDelegate.orderAnApple),
keyEquivalent: "")
statusBarMenu.addItem(
withTitle: "Cancel apple order",
action: #selector(AppDelegate.cancelAppleOrder),
keyEquivalent: "")
// Setting menu
menu = statusBarMenu
}
@objc func statusBarButtonClicked(sender: NSStatusBarButton) {
let event = NSApp.currentEvent!
if event.type == NSEvent.EventType.rightMouseUp {
statusBarItem.popUpMenu(menu)
} else {
print("Left click!")
}
}
@objc func orderAnApple() {
print("Ordering a apple!")
}
@objc func cancelAppleOrder() {
print("Canceling your order :(")
}
}
但是 Xcode 说openMenufunc 在 10.14 中被弃用，并告诉我Use the menu property instead.我有没有办法使用新的 API 实现所需的行为？
显示菜单的常用方法是将菜单分配给状态项，单击状态项按钮时将显示该菜单。 由于popUpMenu已弃用，因此需要另一种方式在不同条件下显示菜单。 如果希望右键单击使用实际状态项菜单，而不仅仅是在状态项位置显示上下文菜单，则可以将状态项菜单属性保留为零，直到您想要显示它。
我已经调整了您的代码以将statusBarItem和statusBarMenu引用分开，仅将菜单添加到单击的操作方法中的状态项。 在操作方法中，添加菜单后，对状态按钮执行正常单击以删除菜单。 由于状态项在单击按钮时将始终显示其菜单，因此添加了NSMenuDelegate方法，用于在菜单关闭时将菜单属性设置为nil，从而还原原始操作：
import Cocoa
@NSApplicationMain
class AppDelegate: NSObject, NSApplicationDelegate, NSMenuDelegate {
// keep status item and menu separate
var statusBarItem: NSStatusItem!
var statusBarMenu: NSMenu!
func applicationDidFinishLaunching(_ aNotification: Notification) {
let statusBar = NSStatusBar.system
statusBarItem = statusBar.statusItem(withLength: NSStatusItem.squareLength)
statusBarItem.button?.title = "🍎"
statusBarItem.button?.action = #selector(self.statusBarButtonClicked(sender:))
statusBarItem.button?.sendAction(on: [.leftMouseUp, .rightMouseUp])
statusBarMenu = NSMenu(title: "Status Bar Menu")
statusBarMenu.delegate = self
statusBarMenu.addItem(
withTitle: "Order an apple",
action: #selector(AppDelegate.orderAnApple),
keyEquivalent: "")
statusBarMenu.addItem(
withTitle: "Cancel apple order",
action: #selector(AppDelegate.cancelAppleOrder),
keyEquivalent: "")
}
@objc func statusBarButtonClicked(sender: NSStatusBarButton) {
let event = NSApp.currentEvent!
if event.type == NSEvent.EventType.rightMouseUp {
print("Right click!")
statusBarItem.menu = statusBarMenu // add menu to button...
statusBarItem.button?.performClick(nil) // ...and click
} else {
print("Left click!")
}
}
@objc func menuDidClose(_ menu: NSMenu) {
statusBarItem.menu = nil // remove menu so button works as before
}
@objc func orderAnApple() {
print("Ordering a apple!")
}
@objc func cancelAppleOrder() {
print("Canceling your order :(")
}
}
这是可能的方法。菜单位置可能会有更准确的计算，包括考虑userInterfaceLayoutDirection的可能差异，但想法保持不变 - 在手动控制下处理可能的事件，并自行决定对每个事件执行的操作。
代码中注释的重要位置。(在 Xcode 11.2、macOS 10.15 上测试(
@NSApplicationMain
class AppDelegate: NSObject, NSApplicationDelegate {
var statusBarItem: NSStatusItem!
func applicationDidFinishLaunching(_ aNotification: Notification) {
let statusBar = NSStatusBar.system
statusBarItem = statusBar.statusItem(
withLength: NSStatusItem.squareLength)
statusBarItem.button?.title = "🍎"
// Setting action
statusBarItem.button?.action = #selector(self.statusBarButtonClicked(sender:))
statusBarItem.button?.sendAction(on: [.leftMouseUp, .rightMouseUp]) // << send action in both cases
let statusBarMenu = NSMenu(title: "Status Bar Menu")
statusBarMenu.addItem(
withTitle: "Order an apple",
action: #selector(AppDelegate.orderAnApple),
keyEquivalent: "")
statusBarMenu.addItem(
withTitle: "Cancel apple order",
action: #selector(AppDelegate.cancelAppleOrder),
keyEquivalent: "")
// Setting menu
statusBarItem.button?.menu = statusBarMenu // << store menu in button, not item
}
@objc func statusBarButtonClicked(sender: NSStatusBarButton) {
let event = NSApp.currentEvent!
if event.type == NSEvent.EventType.rightMouseUp {
print("Right click!")
if let button = statusBarItem.button { // << pop up menu programmatically
button.menu?.popUp(positioning: nil, at: CGPoint(x: -1, y: button.bounds.maxY + 5), in: button)
}
} else {
print("Left click!")
}
}
@objc func orderAnApple() {
print("Ordering a apple!")
}
@objc func cancelAppleOrder() {
print("Canceling your order :(")
}
}
我在macOS Catalina上使用此代码。10.15.2. ( Xcode 11.3(.
左键单击它触发操作。右键单击它显示菜单。

我在卡塔琳娜身上使用了这段代码。我不像其他一些答案所建议的那样performClick，而是必须手动定位弹出窗口。这适用于我使用外部显示器。
func applicationDidFinishLaunching(_ aNotification: Notification) {
statusItem = NSStatusBar.system.statusItem(withLength: NSStatusItem.variableLength)
statusItem.button?.action = #selector(onClick)
statusItem.button?.sendAction(on: [.leftMouseUp, .rightMouseUp])
menu = NSMenu()
menu.addItem(NSMenuItem(title: "Quit", action: #selector(NSApplication.terminate(_:)), keyEquivalent: "q"))
menu.delegate = self
}
@objc func onClick(sender: NSStatusItem) {
let event = NSApp.currentEvent!
if event.type == NSEvent.EventType.rightMouseUp {
// right click, show quit menu
statusItem.menu = menu;
menu.popUp(positioning: nil,
at: NSPoint(x: 0, y: statusItem.statusBar!.thickness),
in: statusItem.button)
} else {
// main click
}
}
@objc func menuDidClose(_ menu: NSMenu) {
// remove menu when closed so we can override left click behavior
statusItem.menu = nil
}
从这里已经给出的伟大答案中学习，我想出了一个替代方案。
此方法的优点是您只需设置一次NSMenu，而不必再忙于设置或删除它。
设置NSStatusBarButton
let status = NSStatusBar.system.statusItem(withLength: NSStatusItem.variableLength)
status.button!.image = NSImage(named: "status")
status.button!.target = self
status.button!.action = #selector(triggerStatus)
status.button!.menu = /* your NSMenu */
status.button!.sendAction(on: [.leftMouseUp, .rightMouseUp])
接收操作
@objc private func triggerStatus(_ button: NSStatusBarButton) {
guard let event = NSApp.currentEvent else { return }
switch event.type {
case .rightMouseUp:
NSMenu.popUpContextMenu(button.menu!, with: event, for: button)
case .leftMouseUp:
/* show your Popup or any other action */
default:
break
}
}
