调整嵌套 NSView 的大小
为了对各种独特的视图进行分类，我有一个精心设计的设置：通过工具栏选择主要类别，然后在类别的 NSScrollView 中选择特定窗格。这看起来像：窗口 -> NSViewController 控制五个视图 ->控制 X 视图的每个视图的子 NSViewController ->每个视图都包含一个核心图。简而言之，几乎每条路径的末尾都有一个核心图 CPLayerHostingView 的嵌套 NSViewController。
在我回答我的问题之前，请随时指出这是一个糟糕的实现。就用户友好性而言，我认为这是有道理的，但是嵌套对象的数量让我想知道是否有更好的方法。
现在，假设我已经以最好的方式设计了它，问题本身：假设我选择了一个类别，然后选择了其中的一个子项，并且正在查看渲染的图表。如果调整窗口大小，我希望图表能够适当调整大小。在 Interface Builder 中，我已经完成了实现这一目标所需的一切：从 CPLayerHostingView 到主窗口中的 NSView 的所有内容都已设置为在所有方向上自动调整大小。尽管如此，如果我在运行时调整大小，图形将保持静止并且不会调整大小或移动。在具有零个或一个 NSView 层的设计中，这会更容易调试，但在这种情况下我没有想法。
我可以使用哪些技巧（编程式的或基于 IB 的）来确保 NSView 根据窗口大小调整很多很多级别？
In order to categorize a wide variety of unique views, I have an elaborate setup: main categories are selected via a toolbar, and then specific panes are selected in a category's NSScrollView. This looks like: window -> NSViewController controlling five views -> sub-NSViewController for each view controlling X views -> each view contains a core-plot graph. In short, nested NSViewControllers with a core-plot CPLayerHostingView at the end of nearly every path.
Before I even get to my question, feel free to point out that this is a poor implementation. In terms of user-friendliness, I think it makes sense, but the sheer number of nested objects makes me wonder if there's a better way.
Now then, assuming I've designed it the best possible way, the question itself: suppose I have selected a category and then a sub-item within, and am looking at a rendered graph. I desire the graph to resize appropriately if the window is resized. In Interface Builder I have done everything necessary to make this happen: everything from the CPLayerHostingView to the NSView in the main window have been set to autosize in all directions. Despite this, if I resize at runtime, the graph stays still and does not resize or move. In a design with zero or one NSView tiers this would be much simpler to debug, but I'm out of ideas in this scenario.
What tricks, programmatic or IB-based, can I use to make sure an NSView resizes according to a window resize many, many levels up?

您不仅需要设置弹簧和支柱，还需要确保选中“自动调整子视图大小”。
Not only do you need to set the springs and struts, but you also need to make sure "Autoresizes Subviews" is checked.
