GetHeightForHeader and GetViewForHeader not called

Question

I am working on a tableview which has two sections. And I would like to add a headerView in the second section header.

I have implemented the following code. It cal

Answer 1

I had the same problem just realised I was setting the delegate and the source like so:

Table.Delegate = new TableDelegate(this); //remove this bit
Table.Source = new TableSource<string>(list, Table);

I realised that I should be using only UITableViewSource and not setting both.

UITableViewSource replaces the following two classes, which are still available in Xamarin.iOS but are not normally required:

UITableViewDataSource – An Objective-C protocol that is modeled in Xamarin.iOS as an abstract class. Must be subclassed to provide a table with a view for each cell, as well as information about headers, footers and the number of rows and sections in the table.

UITableViewDelegate – An Objective-C protocol that is modeled in Xamarin.iOS as a class. Handles selection, editing features and other optional table features.

Xamarin docs

I just moved my rowselected method into my TableSource and it now calls the TitleForHeader and GetViewForHeader methods (they are not mutually exclusive) and only set the source no delegate.

Answer 2

Had the same issue, I just forgot to set the delegate in viewDidLoad

public override void ViewDidLoad()
{
     base.ViewDidLoad();

     TableView.DataSource = new YourViewControllerTableDataSource();
     TableView.Delegate = new YourViewControllerTableDelegate();

}
