我试图做一个简单的NSTouchBar有3个级别的NSPopoverTouchBarItem，所以基本上它是这样的：NSTouchBar多层次NSPopoverTouchBarItem
我有3 NSButton和1 NSPopoverTouchBarItem主要NSTouchbar其打开第二NSTouchbar
第二和1 NSPopoverTouchBarItem其打开第三NSTouchbar
问题是，当我尝试打开第三个NSTouchbar，好像第二个NSTouchbar被解雇了，有时并没有打开第三个。
此外，当打开第三个，当我们关闭，我们去的第一个NSTouchbar，而不是第二NSTouchbar
下面是代码，应该是简单，应该工作（我使用Xcode的触摸栏中模拟器）

这看起来像苹果的SDK的错误。另一个原因是，我无法找到任何像您尝试实现的具有两种弹出级别的系统触摸条。我的建议是使用像Apple [NSTouchBar目录]（https://developer.apple.com/library/content/samplecode/NSTouchBarCatalog/Introduction/Intro.html#//apple_ref/doc/uid/TP40017550）中的Scrubber来让更多的物品只能进入两个级别的弹（（至少在他们修复之前）。 –
