put the sigUp form(includes several textField s) into the scroll Viewer template(iphone)

Question

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.

But the form itself jumps up and cover the whole screen,

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?

- (UIView *)signUpForm
{

if      (!_signUpForm) {
        CGRect frame = CGRectMake(0.0, kSignUpViewVisibleHeight, kDeviceWidth, 310.0);
        UIView *container = [[UIView alloc] initWithFrame:frame];

        CGFloat y = 15.0;
        frame = CGRectMake(15.0, y, kDeviceWidth - 2*15.0, kDefaultTextFieldHeight);
        UITextField *field = [[UITextField alloc] initWithFrame:frame];
        field.placeholder = @"Email*";
        field.keyboardType = UIKeyboardTypeEmailAddress;
        [container addSubview:field];
        self.Email = field;
        self. Email.delegate = self;
            self.Email.clearButtonMode = UITextFieldViewModeWhileEditing;

        CGFloat spacing = 8.0;
        y = frame.origin.y + kDefaultTextFieldHeight + spacing;
        frame = CGRectMake(15.0, y, kDeviceWidth - 2*15.0, kDefaultTextFieldHeight);
