xcode - NSToolbar - 工具栏空间项 - 打破默认约束

Question

如果我通过小尺寸、图标和文本更改应用程序中 NSToolbar 的大小，则应用程序会因不满足的约束而制动(尝试关闭自动布局，或让应用程序生成其布局)

我的窗口由工具栏和内部(左/右)分割 View 组成

[81687:303] Unable to simultaneously satisfy constraints:
(
    "<NSAutoresizingMaskLayoutConstraint:0x100635620 h=--& v=--& V:[NSToolbarItemViewer:0x101b4d930(5)]>",
    "<NSAutoresizingMaskLayoutConstraint:0x100634b30 h=--& v=-&- V:|-(11)-[_NSToolbarSpace:0x101b49a00]   (Names: '|':NSToolbarItemViewer:0x101b4d930 )>",
    "<NSAutoresizingMaskLayoutConstraint:0x100634ad0 h=--& v=-&- V:[_NSToolbarSpace:0x101b49a00]-(12)-|   (Names: '|':NSToolbarItemViewer:0x101b4d930 )>"
)

Will attempt to recover by breaking constraint 
<NSAutoresizingMaskLayoutConstraint:0x100634b30 h=--& v=-&- V:|-(11)-[_NSToolbarSpace:0x101b49a00]   (Names: '|':NSToolbarItemViewer:0x101b4d930 )>

Set the NSUserDefault NSConstraintBasedLayoutVisualizeMutuallyExclusiveConstraints to YES to have -[NSWindow visualizeConstraints:] automatically called when this happens.  And/or, break on objc_exception_throw to catch this in the debugger.

当我可视化约束错误时

编辑:看起来“工具栏空间项目”打破了约束，如果我删除它，我运行得很好

看起来像一个错误，我最终使用空白 NSView 添加了自己的空间项目
