Thank you. Really, thank you. I'm not sure why the world works as it does, but so often when I am attempting to learn or accomplish something, within a day or so something comes along that exactly matches what I need. In this case, I had a desire to dig into an Obj-C project yesterday to try yet again to really learn it. The Apple tutorial is extensive, if verbose. This introduction is exactly what I need at this moment to get me through the knowledge gap.
