我已经为iTunes创建了一个音量控制器，但我希望这个应用程序在OS X系统菜单栏上放置一个图标并让我的滑块控制器下拉。

You need to create an NSStatusItem in your app. Have a look at the Status Bars documentation .

You would normally create a faceless background app by setting the LSUIElement key in your Info.plist file to YES and have the app create the status item on launch.
