Books About Darwin/MacOS X Programming?

Otter asks: "I've been dabbling in C++ programming with Linux and Qt. I'm interested in trying Darwin or MacOS X development but am not sure where to start. Mac programming books only deal with traditional MacOS. I could use CodeWarrior and Carbon, but if I'm going to start out, I might as well use the NeXT/Cocoa methods that are the way of the future and, I've heard, a lot better. So, how do I get started? Apple's Web site is still oriented towards the traditional API's and the move to Carbon. Are there any books that would give me a good introduction? Any tutorials? Can I continue with C++ or do I need to learn Objective C or Java? Does Code Warrior support Cocoa development (in the IDE and/or in the documentation)? "
