Awesome.

I had $1 left in my iTunes account and decided to spend it on this, just because Im just like you.
Im 13 and trying to learn iOS/Cocoa development, and this is really encouraging. Thank you.

PS: I suggest you open iBooks and search for Apples UIG. (User interface guidelines) its a free book, and I highly recommend it.
