Create a UIViewController for my class source, how to?

I have this class to create the date source. How do I create a UIViewController using this class?

public partial class JogosSource : UITableViewSource {

    List<TableItem> tableItems; 
    string cellIdentifier = "TableCell";

    public JogosSource (List<TableItem> items)
    {
    }

    public override int RowsInSection (UITableView tableview, int section)
    {
    }

    public override void RowSelected (UITableView tableView, NSIndexPath indexPath)
    {
    }

    public override UITableViewCell GetCell (UITableView tableView, MonoTouch.Foundation.NSIndexPath indexPath)
    {
    }
}

I'm not pretty sure I understand your question.

UITableViewSource is a class that combines UITableViewDelegate and UITableViewDataSource into one convenient class that contains the methods of both.

So, if you want to use that class, JogoSource in your case, as written in MT doc you need to

Assign an instance of this object to the UITableView.Source property.

To create a UITableView element you could follow three different ways:

  • Subclass an UITableViewController (this class has a table view its own)

  • Subclass a UIViewController with its own XIB, drag the table within the main view and link it with an outlet

  • Subclass a UIViewController (with its own XIB, this is optionally), create the table by code

Setting the Source for your table view instance could be done in ViewDidLoad method. Here you are sure that outlets, for example, are set up correctly.

this.YourTable = new JogoSource(yourItems);

Simple advice

Usually, when you deal with a UITableViewSource class you could also inject within its constructor the controller that "controls" that source. This could be useful for example in situations when you deal with UINavigationController.

So, I would change the ctr of JogoSource as

public JogosSource (UIViewController injectedController, List<TableItem> items)
{
    // _controller is a private var of type UIViewController
    _controller = injectedController;
}

If your controller is inserted, for example, in a UINavigationController and you need to show some details when you select a row, by means of _controller you access the parent (an instance of UINavigationController).

P.S. There are other possibilities to create a table but I listed the main ones. Furthermore, check the code since I've written by hand.

Hope that helps.
