我正在尝试使用

从所选索引中删除项目
[toolbar removeItemAtIndex:9];

这给了我这个

Unable to simultaneously satisfy constraints:
(
    "<NSAutoresizingMaskLayoutConstraint:0x600000287f30 h=--& v=--& V:[NSToolbarItemViewer:0x10040b290(5)]>",
    "<NSAutoresizingMaskLayoutConstraint:0x600000287d00 h=--& v=-&- V:|-(10)-[_NSToolbarSpace:0x60000015b280]   (Names: '|':NSToolbarItemViewer:0x10040b290 )>",

Will attempt to recover by breaking constraint

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.

使用此removeItemAtIndex是否打破了基本约束?或者是否有其他方法可以在不破坏约束的情况下删除项目。

感谢。
