As Matt Neuburg states in his book:

Autoresizing is a matter of conceptually assigning a subview “springs and struts.” A spring can stretch; a strut can’t. Springs and struts can be assigned internally or externally. Thus you can specify (using internal springs and struts) whether and how the view can be resized, and (using external springs and struts) whether and how the view can be repositioned.

And

Autolayout, depends on the constraints of views. A constraint (an instance of NSLayoutConstraint) is much more sophisticated than the "autoresizingMask" it’s a full-fledged object with numeric values, and can describe a relationship between any two views (not just a subview and its superview).
