This App demonstrates how to use an iPhone Development Library that generates QR Codes and has App users post them to their Facebook's wall. Their Facebook friends can then scan the codes from the screen using one of many QR code readers available on the App Store. Red Lazer is highly recommended, http://bit.ly/fw7uvo The library to helps your App gain a massive amount of exposure as users will broadcast that they like your App to all of their Facebook friends. Even if you are not a developer, users can use this App to broadcast Apps that they would like to recommend to friends. If any developer is interested in using this library, please check it out at https://github.com/jgank/QR-Code-Facebook-Post-for-iPhone
