title: put the sigUp form(includes several textField s) into the scroll Viewer template(iphone)
body: <p>I have designed a sign up form like following , which contains several textfields and every time user clicks on a textfield the keyboard comes up or the datePicker for birthday date. the sign up form comes up using tap.</p>
  
  <p>But the form itself jumps up and cover the whole screen,</p>
  
  <p>How can I change the viewDidLoad and also the design of my code to 1)have the sign up form in a scroll view format so that I avoid the form jump up in the screen?</p>
