我有 3 个 NSToolbarItems，第一个工作得很好，另外两个，每次我选择它们时都会抛出

[16392:513506] -[NSToolbarItem isEqualToString:]: unrecognized selector sent to instance 0x6080001203c0

我尝试从情节提要断开并重新连接它们，但没有任何改变。IBAction 甚至没有被调用。

 func toolbarSelectableItemIdentifiers(toolbar: NSToolbar) -> [AnyObject] {
//    let array = toolbar.items.filter { contains(Identifier.allValues, $0.itemIdentifier ) }//wrong!
return Identifier.allValues
}

委托只需要标识符的名称，而不是可选项目本身。
