I wanted to get some advice on how to make a iPhone app work with an existing webapp. Specifically, how do I make it so that if a user enters in something (say text into a textbox), it will effectively put that information into the existing webpage. An example of this would be entering in a username and password, clicking a button, or checking a box on a survey. My hope is that it would essentially just create a native interface for the webpage. Any and all guidance would be greatly appreciated. Thanks!
