一、需求来源
mac 工具栏开发，非常常见的一种功能，但是中文资源异常的少见，或者是xib 形式，花了一天时间查看了大量的国外相关资料博客最终纯代码实现。
二、使用示例
import Cocoa
import SwiftExpand
class NNTabViewController: NSWindowController {
// var toolbar: NSToolbar?
lazy var toolbar: NSToolbar = {
let toolbar = NSToolbar(identifier:"ScreenNameToolbarIdentifier")
toolbar.allowsUserCustomization = true
toolbar.delegate = self
return toolbar
}()
