如何在类外更改NSStatusItem

import Cocoa

class StatusItemManager {
    static let shared = StatusItemManager()
    
    var statusItem: NSStatusItem?
    
    private init() {
        statusItem = NSStatusBar.system.statusItem(withLength: NSStatusItem.squareLength)
        statusItem?.button?.title = "My App"
        
        let menu = NSMenu()
        menu.addItem(withTitle: "Option 1", action: #selector(option1Clicked), keyEquivalent: "")
        menu.addItem(withTitle: "Option 2", action: #selector(option2Clicked), keyEquivalent: "")
        statusItem?.menu = menu
    }
    
    @objc func option1Clicked() {
        // 处理Option 1的点击事件
    }
    
    @objc func option2Clicked() {
        // 处理Option 2的点击事件
    }
}

// 在类外更改NSStatusItem的标题和菜单项
StatusItemManager.shared.statusItem?.button?.title = "Updated Title"
StatusItemManager.shared.statusItem?.menu?.addItem(withTitle: "Option 3", action: #selector(option3Clicked), keyEquivalent: "")

@objc func option3Clicked() {
    // 处理Option 3的点击事件
}
