如何在iOS Storyboard中使两个约束相互匹配？

Question

I have a view that is sized to the width of the screen with a 1x1 ratio of width to height (matching height). I have a view below that square view that is a set height from the bottom. What I want is for the top view to be centered in the blank space. So I would love to just set 1 constraint for the top and 1 constraint for the bottom to say, match. Then if there are x number of points of available, each constraint should be size x / 2.

So far, I haven't been able to find a constraint setting that can do this. Could someone describe how to do this?

通常，您添加2个透明视图，上方1个，下方1个，将边缘固定到现有视图，并将2个新视图设置为相等的高度。
