With iOS7 being as complete a redesign as we've had for iOS since the release of the iPhone, as a student looking into starting to learn iOS development this summer, does the new iOS change what I should learn? Are iOS6 books similar enough to learn from, or should I wait for new resources to come out?
I'd go for iOS 6 books to get you started.
Later you can join the (free) developer account [1] and watch some of the WWDC-videos about why and what Apple has changed in iOS 7.
