我如何制作一个带有标签视图的视图，可滚动？

The setup I'll describe is for an NSTabView that will pin to the top, left, and right sides of the scroll view. Note the NSTabView could be replaced with any other NSView, the setup is the same.

Starting with you putting a scroll view into the xib/storyboard, you'll have NSScrollView -> NSClipView -> NSView (document view). Constrain the NSScrollView to the edges of the window. Drop your NSTabView onto the NSView instance. Add constraints so that your NSTabView edge constraints equal the NSView and define a height constraint either explicitly or implicitly with other content inside the tab view that defines it.

Personally I like to change the NSView instance (document view) layout to use constraints, by default it uses autoresizing masks and this makes it difficult to keep it in sync with the NSTabView. We want the document view to be pinned to the top, left, and right sides of the scroll view. The size of this view is what determines the scrollable region so we want it to be the same size as the NSTabView so the height of the tab view will determine the scrollable area.

To change this, select the document view, and under the Size Inspector we want to change the "Layout" type to "Automatic".

Lastly, add constraints to the top, left, and right and you should be good to go.

If you want the scroll view to start at the top rather than the bottom, you should subclass the document view and override isFlipped:

class FlippedView: NSView {
    override var isFlipped: Bool { true }
}
