我有一个GridNode继承自CPSplitView它的类，用于包装类型的对象GridELement。a 的每个连续拆分都GridNode将其分成两个新GridNodes的（包含GridElements与其父级一起调整大小）。

另一个类 -GridToolbar继承自GridElement. 它应该基本上具有相同的行为，GridElement尽管大小不应该自动改变（因为容器被调整大小）但只有在用户拖动拆分器之后。

问题是，即使我将其设置AutoresizingMask为特定方向（因为工具栏可以是垂直或水平的），它仍然会在它们两个中调整大小。

关于我可以做些什么来防止这种情况发生的任何建议？

  return self;

我在这里收到了一个有用的建议。创建我自己的委托，GridNode在拖动分隔线时根据固定值集处理 's 子视图的自动调整大小是我所要做的。
