我是否必须使用监视鼠标移动等的视图来手动管理所有这些？

你必须自己做所有的工作。您将需要跟踪视图中的对象及其位置，并进行所有鼠标跟踪和视图更新。
然而，这实际上并不是很困难，Apple 在其 草图示例代码。
You have to do all the work yourself. You will need to keep track of the objects in your view, their positions and do all the mouse tracking and view updating.
However, this is not actually very difficult, and Apple has provided a very complete example in its Sketch sample code.
我建议在您希望视图可调整大小的位置绘制一些按钮。然后开始跟踪视图中的鼠标事件。现在，当用户在单击某个位置时拖动鼠标时，只需相应地更改视图的框架即可。所有这些都应该可以在 NSView 的子类中实现。
I suggest drawing some buttons where you want the view to be resizable. Then start tracking mouse events in the view. Now, when a user drags its mouse while clicking on when of your spots, just change the view's frame accordingly. All of that should be possible to implement in a subclass of
NSView.
