Okay, the good news is that this turns out to be false! It turns out that you *can* exercise the autolayout engine for any view hierarchy by sending layoutIfNeeded to it. A lucky discovery.
So I can certainly make a hierarchy and lay it out with constraints and autolayout, without putting that hierarchy into the visible interface.
My problem now is just that I can't seem to find the autolayout fu that will cause a view containing a label to be laid out by the label, rather than the other way round.
In other words, I have a view superview and a label subview; I am resizing the label by giving it text content and saying sizeToFit; and now the label is the right size. So now I am going to exercise autolayout, and I want the view superview to resize to meet the constraints relating the superview to the label - what's happening instead is that the label is resizing again and the superview is staying the same.
