Monotouch.Dialog: ScopeBar hidden by SectionHeader - ios

Question

Using MonoTouch.Dialog I add a simple table and add a ScopeBar:
this.Style = UITableViewStyle.Plain;
this.EnableSearch = true;
this.AutoHideSearch = false;
this.SearchPlaceholder = "Search".t();
UISearchBar sb = TableView.TableHeaderView as UISearchBar;
if (sb != null)
{
sb.ScopeButtonTitles = new string[] { "Girl".t(),"Boy".t(),"All".t() };
sb.ShowsScopeBar = true;
sb.SizeToFit();
}
Looks good:
When I set the Section and give it a Title, the Section appears on top of the scope bar:
Section secMain = new Section("Top 100".t());

To do this, you need to change MonoTouch.Dialog.DialogViewController and make void SetupSearch() protected virtual.
Then, in your controller override the SetupSearch method with the code that follows. The downside to this approach is that you have to use a custom search delegate. But from seeing the response to some of your other questions, it appears you are already doing that.
protected override void SetupSearch()
{
SearchBar = new UISearchBar(new RectangleF (0, 0, TableView.Bounds.Width, 90))
{
Delegate = new MySearchBarDelegate(this),
Placeholder = "Search".t(),
ShowsScopeBar = true,
ScopeButtonTitles = new [] { "Girl".t(),"Boy".t(),"All".t() },
SelectedScopeButtonIndex = 0,
};
TableView.TableHeaderView = SearchBar;
}
public class MySearchBarDelegate : UISearchBarDelegate
{
MyViewController _container;
public SearchDelegate (MyViewController container)
{
_container = container;
}
public override void SelectedScopeButtonIndexChanged (UISearchBar searchBar, int index)
{
_container.SearchScopeChanged(searchBar, index);
}
public override void OnEditingStarted (UISearchBar searchBar)
{
searchBar.ShowsCancelButton = true;
_container.StartSearch ();
}
public override void OnEditingStopped (UISearchBar searchBar)
{
searchBar.ShowsCancelButton = false;
_container.FinishSearch ();
}
public override void TextChanged (UISearchBar searchBar, string searchText)
{
_container.PerformFilter (searchText ?? "");
}
public override void CancelButtonClicked (UISearchBar searchBar)
{
searchBar.ShowsCancelButton = false;
_container.SearchBar.Text = "";
_container.FinishSearch ();
searchBar.ResignFirstResponder ();
}
public override void SearchButtonClicked (UISearchBar searchBar)
{
_container.SearchButtonClicked (searchBar.Text);
}
}
