Though lecture #7 is called animation and auto layout the title of the last lecture would be better fit, because it discusses mainly views and gestures.
The theory part describes how to draw into views using code and how to use different kind of gestures. The demo at the end of the lecture shows their usage.
The code for this lecture is available at github as well as from Stanford.
The lecture as well as its slides are available via iTunes called “7. Animation, Auto Layout”.
