How To parse UITextField value from one Nib to another

Question

How can I parse UITextField value from one Nib file to another, By initWithNibName

Here is the Code for the First View

-(IBAction)testbuttonPressed:(id)sender
{
    //test.text=@"hello H R U";
    detailsViewController=[[FlipsideViewController alloc] initWithNibName:@"FlipsideView" bundle:nil];
    detailsViewController.address1=txtName;
    [UIView beginAnimations:@"flipping view" context:nil];
    [UIView setAnimationDuration:1];

    [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
    [UIView setAnimationTransition: UIViewAnimationTransitionCurlDown forView:self.view cache:YES];
    [self.view addSubview:detailsViewController.view];

    [UIView commitAnimations];
}

• txtName is UITextField here.
• and In the FlipsideViewController address1 is UITextField
• and in the FlipsideViewController.m I am trying to fetch it by address1.text.

Now when I am running the app. First View Appear with the UITextField to which txtName is attached. On Button Click new View appeared by It is not Printing address1.text value which I have inputed in the previous view
