如何在 NSStatusBar 中绘制自定义视图？

Question

我目前有一个带有显示标题的NSStatusBara 。NSStatusBarItem但我不想用自定义替换标题/文本NSView。我怎样才能做到这一点？

我目前有：

func applicationDidFinishLaunching(_ aNotification: Notification) {
    let statusBar = NSStatusBar.system
    statusBarItem = statusBar.statusItem(withLength: NSStatusItem.variableLength)
    statusBarItem.button?.title = "My Menu Bar App"
}

假设我不想用以下内容替换标题：

let view = NSView(frame: NSRect(x: 0, y: 0, width: 40, height: 40))
view.layer?.backgroundColor = NSColor.yellow.cgColor

我怎样才能做到这一点？我尝试将其作为子视图添加到按钮中，但没有成功。

• 在类的顶层创建对状态项的强引用

  let statusItem = NSStatusBar.system.statusItem(withLength: NSStatusItem.variableLength)
  

• applicationDidFinishLaunching启用图层并将视图添加到按钮的子视图中

  func applicationDidFinishLaunching(_ aNotification: Notification) {
  
      let view = NSView(frame: NSRect(x: 0, y: 0, width: 22, height: 22))
      view.wantsLayer = true
      view.layer?.backgroundColor = NSColor.yellow.cgColor
      statusItem.button?.addSubview(view)
  
  }
