In September, I wrote about our Mac OS X 10.7 Lion Auto Layout. As auto layout is one of the building blocks for laying out user interface for next major update of Startupizer, and being new technology, I came across few issues that took me a while to figure out. In this post, I’ll cover some of them for my future reference and hopefully shed some light for those of you stumbling upon the same walls.

In my previous post (part 1 and part 2), I talked about new Lion feature - view-based table views. I skimmed over auto layout briefly. In this post, I’m going to talk about it a bit more. We’ll update the example app from previous post to use auto layout and see what changes are required when porting existing code. In addition, we’ll take a look at how we can use auto layout with view controllers and dynamic view hierarchies.
