I finished the highly detailed walkthrough for the Calculator assignment (it basically tells you step by step how to build this project). I added a few new buttons and some color, then recorded building and running it on the iOS Simulator. Enjoy.
The next step is to follow the actual assignment and probably add some more functionality. Fun!
//edit - so annoying, I cannot get a decent sized and viewable video to embed on this page. You can either view the small YouTube video here, or click through the the full YouTube site and view full screen there. Why wouldn't they just include the full screen button on the embedded video? :-\
