I'm creating the cell here
public override UITableViewCell GetCell (UITableView tableView,
NSIndexPath indexPath)
{
UITableViewCell cell = tableView.DequeueReusableCell
(kCellIdentifier);
if (cell == null)
{
You must create a cell here:
cell = new AccessibilityExtensions
(UITableViewCellStyle.Default, kCellIdentifier);
}
cell.TextLabel.Text = list[indexPath.Row].Name;
cell.Accessory =
UITableViewCellAccessory.DisclosureIndicator;
cell.SetAccessibilityLabel("text");
//UITableViewCell cell1 = new
AccessibilityExtensions();
return cell;
}
is this where i would call the extension?
AccessibilityExtensions is a C# extension class. You can't create
instances from it.
Add the attached file to your project, and whenever you want to
set an accessibility label to a UIView descendant, you just
invoke the extension method on the instance.
