Passing Data Between ViewControllers Using Storyboards and Segues (Video)

Although this may not be the proper way to exchange data between ViewControllers using Storyboards, this video tutorial offers a solution to the problem. It may seem easy at first, but it isn’t very intuitive for those of us who are just starting out with iPhone and iPad app development.

The problem to solve is this: passing 2 variables of type NSString from one ViewController to another using Storyboards. The solution is to add a "segue" (loosely speaking, a segue is a "pipe" between ViewControllers), and set the attributes of the second ViewController from the first ViewController (in this case, two attributes of type NSString).

This data will be passed through a specific "segue" that has an identifier, and it is done through the following "prepareForSegue" method:

-(void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
    if ([[segue identifier] isEqualToString:@"NOMBRE_DEL_SEGUE"]) {
        NOMBRE_VIEWCONTROLLER_DESTINO *segundoView = [segue destinationViewController];
        segundoView.NOMBRE_ATRIBUTO = VALOR_A_PASAR;

    }
}

Below is a video showing how this simple app for passing data between Views using Storyboards and Segues was built:
