Hey guys, I'm interested in getting into some Mac programming as a hobby. I have primarily been a Windows-programming guy, and have a intermediate level experience with Visual Basic .NET and have written several apps using it for my company. While in college, WAY back in the beginning (like Freshman year) I had a class on C and took about half a semester of C++ the following semester. I'm interested in learning more about the development tools built-in to OS X--namely Xcode and Interface Builder. As of right now, I have not the slightest idea how to use either of these. I do, however, have the basic understanding of programming necessary for some books. It's also my understanding that these tools are primarily focused on Objective-C, of which I have no experience. Bottom line, I'd like some recommendations for a (some?) book(s) to get to read up on the subject. I've got my eye on "Beginning Mac OS Programming" by Michael Trent and Drew McCormack. Does anyone have any experience with this particular book? Any other recommendations to get me started? We're about to take a trip during Thanksgiving to visit my wife's family, so I'm going to have to make a decision quickly so the book can be overnighted from Amazon. Any input soon would be appreciated.
