Xcode: storyboard and data storage in each controller

As you can guess, I'm a new programmer, and I'm having trouble getting a simple thing! I am making an application with multiple controllers. Each controller has text fields and UIsegmentedControl elements. When I switch from one view controller to another (if that matters), the contents of the previous one (text fields and segmented control parameter) are reset. How can I make them keep their previous state? Thanks in advance.

-(void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
    bViewController *deneme = [segue destinationViewController];
    [deneme setPassedValue:label.text];
}

This piece of code will solve your problem, I hope. He retains the mark of what is inside her. And you need to add some more codes for other classes.
