I would like a simple book scanning and selling app written in the language Objective C. The user will have the option to scan the book barcode or input isbn number. The isbn number will be pooled from isbndb.com. The app will display the selling price at [login to view URL] and half.com. The user will have the option to sell the book at either site or continue scanning books. I have a very simple GuI and Pseudo code available when more details are needed.
