Parameters for a Container View

Question

The scenario is as follows:

I own a UIViewController and within this controller I own one UITableViewController added as a ContainerView.

How do I pass parameters between my UIViewController and my ContainerView?

For example, I want to get past mine UIViewController a list of items to be presented in my ContainerView (UITableViewController).

Answer 1

Just you simply have a public method in your UITableViewController and execute it by UIViewController. Let’s assume that your UITableViewController has the following method in its header:

- (void)preencheTabela:(NSArray *)lista;

And the implementation:

- (void)preencheTabela:(NSArray *)lista {
    // TODO preencher sua lista atual com a recuperada
    [self.tableView reloadData];
}

And in his UIViewController, once you have the reference of the Controller with the table that was inserted in container, just run your method:

[self.referanciaTabela preencheTabela:listaEnviada];

Clarifying that it is not for the container that you will pass, and yes to the Controller that’s inside the container. It was clear?

Your reference, already with the container added from the storyboard, is more or less like this, in the viewDidLoad: for example:

self.referanciaTabela = [self.childViewControllers firstObject];
