Need form data from website in iOS app

Let me start by saying I already have 1 app in the store with 2 on the way. I just want to add a new feature to one of them, so I will merge your code with mine. There is a public website where you enter a form field and it returns data. Think of it as a VIN that returns make/model. If a user enters their VIN in a UITextField, I just want the return data to prefill a tableView. But if you can put this data into an array, I can throw it in a table. That's it. Here's the site: [login to view URL] and a value you can enter: 2059282 If you noticed, this is for a coin app. And as an aside, these coin holders not only have a certification number, they also have a barcode. The last 7 digits of the barcode is the certification number. If it's not tremendously difficult to implement a barcode reader, let me knowhow much that would be instead. Thank you for your time!
