swift - 从 ViewController 设置菜单栏图标

Question

如何从另一个 ViewController 更改 MacOS 应用程序的菜单栏图标？

• AppDelegate.swift(初始化菜单栏图标)
• ViewController.swift(尝​​试设置菜单栏图标 ❌)

我找到了这个，但这并没有改变我的菜单栏图标: Mac: How to save alternate app icon in dock OSX xcode

let image = NSImage.init(named: NSImage.Name(rawValue: "AltAppIcon"))
NSApp.applicationIconImage = image

看到 BOINC 图标的菜单栏右下角有自定义暂停符号/徽章了吗？这个应用程序的图标改变了。他们是否改写了该文件的名称并将其更改为“暂停图标”图像？

✅更新*

设置菜单栏图标的 AppDelegate.swift 函数有效:

AppDelegate.swift

func setIcon() {
  let onIcon = NSImage(named: "fv-mini-icon-green")
  statusItem.button?.image = onIcon
}

ViewController.swift

func taskOnIcon() {
  DispatchQueue.main.async(execute: {
    let appDele = NSApplication.shared.delegate as! AppDelegate
    appDele.setIcon()
  })
}

这里有一个方法...

class AppDelegate: NSObject, NSApplicationDelegate {
    var statusBarItem: NSStatusItem!

    func applicationDidFinishLaunching(_ aNotification: Notification) {

        let statusBar = NSStatusBar.system
        statusBarItem = statusBar.statusItem(withLength: 16)

        let button = statusBarItem.button
        button?.image = NSImage(named: "fv-mini-icon-green")
