Got "Couldn't find hybrid.styleproto" in iOS6.1 simulator


Hello everyone.

good book.

I just try the code on the book, but what I got is only grids, and there are some messages printed in console.

2013-08-02 20:34:40.540 Whereami[92411:c07] Couldn’t find default.styleproto in framework

I didn’t know what these were, so I searched Google but found nothing useful.

I downloaded the solution to see if I made some mistakes, but I saw the solution works fine under iOS5.

Could someone explain these? Thank you very much.
