UITableView and GADBannerView - xamarin.ios

Question

I was trying to implement a TableView where between the rows of my source I would like to insert a GADBannerView (sponsored ads by Google AdMob). I currently have a datasource which every time I come to the end add 10 elements like an infinite scroll.
My intention would be to insert an element GADBannerView every 6 rows. How could I do?
UPDATE
As suggested
public override int RowsInSection (UITableView tableview, int section)
{
return (int)Math.Floor (Convert.ToDouble(ViewModel.ListElements.Count / 6) )+ ViewModel.ListElements.Count;
}
public override UITableViewCell GetCell (UITableView tableView, NSIndexPath indexPath)
{
if(indexPath.Row % 6 == 0 && indexPath.Row > 0){
var cell = tableView.DequeueReusableCell (BannerGATableCell.Key) as BannerGATableCell ?? BannerGATableCell.Create ();
_bannerView.LoadRequest (GADRequest.Request);
cell.AddSubview(_bannerView);
return cell;
}
if (indexPath.Row >= 6) {
return base.GetCell (tableView, NSIndexPath.FromRowSection((int)(indexPath.Row - (int)(indexPath.Row / 6)),0));
}
return base.GetCell (tableView, indexPath);
}

Answer 1

First you need to know how many banners will fit into your source.
Say you have 14 rows in total in your source.
Every 6th row is supposed to be a banner.
number of banners == (int)Math.Floor(14f / 6) == 2
So we have one banner at row 6 (index 5) and one at 12 (index 11).
In your RowsInSection() method add 2 to the number of rows you have (for the banners).
Then in GetCell() check if it is time to inject a banner:
if(indexPath.Row % 6 == 0 && indexPath.Row > 0)
{
var bannerCell = tableView.DequeueReusableCell(SOME_SPECIAL_CELL_ID) as BannerCell;
if(bannerCell == null)
{
...
}
bannerCell.SetBannerView(SomeHelper.GetBannerView());
return bannerCell;
}
BannerCell would be a subclass of UITableViewCell you have to create that allows setting the banner. You can also use a normal cell and add the banner view to the ContentView of the cell. But don't forget to remove the subview first.
