How to fetch data from website within the app?

[MarcoAlmeida]

I am developing an app for Lawyers to be used here in Brazil and one of the features of this app is to track the fase of the lawsuit as it develops through time.

It works like this: the user fill a form within the app with the info on the lawsuit and it is stored in a database. Whenever the user wants to know if the lawsuit has any new record, he´ll push a button and will get the records ordered by date.

The website that the app will fetch is Tribunal de Justiça da Paraíba Carregando... the problem is that I don´t know how to code in order to get the app access that site, input the lawsuit number and get the reply displayed on an UIWebView.

So could anyone help me, or just give me a guide on where to find a solution for this??

Thank you, Marco Almeida.
