title: Submit a form in UIWebView
body: <p>I have a form in the UIWebView to interact with a web service, when I submit the form, the data gets sent to a web service and it will return the result to another UIWebView. The two UIWebViews are under a navigation controller, so when the use submits the form, it slides to another view to display the result. Can anyone point me out how I can achieve this? What do I fill in the "action" attribute in the form element? How can I get the user input back to the application so I can use  the web service? I am new to this field, any help will be appreciated. Thanks! </p>

  <p>Update:</p>
  
  <p>Is there a way to save form data from web view back to my program? I think it's better to save form data back to the program (i.e. store params into nsstring) when I click submit button, and then start querying web service.</p>
