Is this ebook still relevant?

Thanks guys...

Question: I have no programming experience whatsoever (other than basic html and css). Do you recommend I take a class in Objective C? I'm definitely right-brained, computer savvy, and have math skills, but how hard is it going to be for a long-out-of-school 54-year old to pick up? In general terms, of course.

If you think it a good idea, do you recommend online courses or what?

Tominator, thanks for the links! That free, more current ebook looks like a great start!
