Slightly out of date, but definitely still worth it.

OK, firstly the edition I received is slightly out of date, it does not have ARC (automatic reference counting) but to be honest, the book teaches you good memory management techniques, the fact you no longer need them, doesn't mean it's not good to learn, as long as you remember to untick it for the exercises or not try to release objects.
It's also missing any reference to story boarding in xcode, but again, remember to untick it when doing the exercises, and then you can follow them using the old xib files instead.
This is a really great read through, I have also purchased Kochan's Objective-C reference book, which does have ARC in it and Sams 24HR, also a 2012 book, as I felt it would be better to read more than one to fully learn.
The book takes you through several applications and is much more like learning from a good interactive teacher (think mad science teacher from school) than a university lecturer. :)
