iphone - What is Auto Layout?

Question

What is Auto Layout - what does it do, and is it an iOS 5 feature?

Since the new iPhone 5 has a bigger screen, all the options on how to optimize your applications for it come down to Auto Layout.

Can you point me to some article about Auto Layout, and how I can adapt it with my project?

Answer 1

I recommend watching the WWDC 2012 session Introduction to Auto Layout for iOS and OS X.

Auto Layout is a new way to define dynamic GUIs. Before, we had autoresizing masks, that described how a subview will resize or move when its superview is resized. With Auto Layout you can do the same and also a lot more complicated GUIs quite easily.
