Hi Tom, I think the problem here is that if you have view A containing textField, and textField is centered in A, there's no constraint expressing anything about A's height. A can go to zero height and still have the textField centered within it.
If you added something giving a height (or fastened the edges of A to the textField), that'd probably do it. -ken On Fri, Nov 8, 2013 at 5:02 PM, Tom Harrington <atomicb...@gmail.com> wrote: > I'm trying to use NSStackView in what should be the most basic way > possible.
