如何定位UITableView（MonoTouch）

Question

Given the following code:

public class MainTableController : UITableViewController
{
    // Allow us to set the style of the TableView
    public MainTableController(UITableViewStyle style) : base(style)
    {
    }

    public override void ViewDidLoad ()
    {   
        TableView.DataSource = new MainTableDataSource();
        TableView.Delegate = new MainTableDelegate(this);

        TableView.BackgroundColor = UIColor.FromPatternImage(UIImage.FromFile ("Content/Background-Home@2x.png"));

        TableView.Bounces = false;

        base.ViewDidLoad ();
    }
}

Given the following output:

How can I update my code so that the group of table cells starts halfway down the page? The actual pixels aren't important, I am just trying to figure out where properties are to modify this.

Answer 1

It's not a good idea to manually position the UITableView in a UITableViewController. That being said I think adjusting the ContentInset property should get you where you need to go:

this.TableView.ContentInset = new UIEdgeInsets(this.TableView.Center.Y, 0, 0, 0);

This should push down the first Section / Cell to the specified UIEdgeInset.Top value.

Edit: As per clarification in comments...

If you need to maintain position of the background view...you might have better luck by creating a HeaderView for the first section and increasing it's frame to a size sufficient enough to move the first cell down:

public override UIView GetViewForHeader (UITableView tableView, int sectionIdx)
{
    if(sectionIdx == 0) { 

        // adjust appropriate index above ^

        var view = new UIView();
        view.Frame = new RectangleF(...) // adjust your frame here
        return view;    
    }
}
