添加子视图时访问父视图
我有一个 ViewController，其中有 2 个不同大小的 NSView。我想将自定义 ViewController 的视图作为子视图添加到这两个 NSView 中，并动态调整大小以填充（两个父视图）。我可以在主布局的实现文件中很好地完成此操作，但它的代码很多。我想让我的自定义 ViewController 完成所有工作。为此，我需要知道要添加自定义视图的视图的高度和宽度。有一个parentViewController属性，但它对我没有任何作用。有没有办法引用正在添加视图的视图？
在我的自定义 ViewController viewDidLoad 方法中，我希望能够拥有
[self.view setFrame:CGRectMake(0, 0,
self.parentViewController.view.frame.size.width,
self.parentViewController.view.frame.size.height)];
，但这里的高度和宽度都是零。
我已经研究了几个小时的文档，但我仍然很困惑。任何帮助将不胜感激。
I have a ViewController that has 2 NSViews in it of different sizes. I'm wanting to add the view of a custom ViewController as a subView to both of these NSViews and have it dynamically size to fill (the 2 parent views). I can accomplish this just fine in the implementation file for the main layout, but its a lot of code. I would like to instead have my custom ViewController do all the work. To do that, I need to know the height and width of the view that I am adding my custom view to. There is a parentViewController property, but it isn't doing anything for me. Is there a way to reference the view that a view is being added to?
In my custom ViewController viewDidLoad method I would like to be able to have
[self.view setFrame:CGRectMake(0, 0,
self.parentViewController.view.frame.size.width,
self.parentViewController.view.frame.size.height)];
but the height and width are both nil here.
I've been digging through documentation for hours and I am still confused. Any help would be much appreciated.

应该首先设置parentViewController 属性。如果没有设置则为零。您还没有指定它是否设置正确。不过，有一种更简单的方法可以做到这一点，假设您的视图的超级视图设置正确。试试这个：
或者如果您需要更改其中的某些内容，请从超级视图的框架中创建矩形。
The parentViewController property should be set in the first place. It will be nil if it is not set. You have not specified if it is set correctly. There is a simpler way to do this though, assuming that your view's superview is set correctly. Try this:
or make the rect from the superview's frame if you need to alter something in there.
