Dave, I have had some great frustrations understanding and then debugging auto-layout issues. I have an application that now can present an arbitrary number of moveable, resizable and overlappable views, which have a fairly rich class hierarchy themselves, within a containing view. I had to dance down a long and very merry path to get all that to work with auto-layout. Looking at demos, looking at WWDC videos, reading sample code, reading documentation, and one judicious post here is what got me over the hump. There is no substitute for lots of hard work and lots of frustration. I’d recommend that you just keep plugging away. That’s what all of us have had to do.
The more I have gotten into auto-layout the more I am grokking the underlying linear algebra, and the more I am understanding what’s going on. For anything complicated veiw-wise, auto-layout has, IMHO, a very steep learning curve. However, it works well and does some marvelous things.
