How can I add sections to my UITableViewCell?

Question

How can I add sections to my UITableViewCell with the Bond framework?

 self.viewModel.items.bind(to: self.tableView) { (item, indexPath, tableView) -> UITableViewCell in
                      let cell = tableView.dequeueReusableCell(withIdentifier: String(describing: ListCell.self),
                                                               for: indexPath) as! ListCell
                       cell.item = item[indexPath.row]
                      return cell
                  }.dispose(in: self.bag)

Regarding the source code,

if you want to override just a title, you should override this class and implement correspond logic for

open class TableViewBinderDataSource<Changeset: SectionedDataSourceChangeset>: NSObject, UITableViewDataSource

but if you want to implement totally custom view, this is much complicated. I don't think that this is possible for this library. the reason is that you should override UITableViewDelegate, but it is used in public protocol ReactiveExtensions that cannot be overridden.

This part of code that I share is work and this is right way in Bond framework — KNK, Nov 08 '19 at 14:34

You must write this class

class  CustomSection<Changeset: SectionedDataSourceChangeset>: TableViewBinderDataSource<Changeset>, UITableViewDelegate where Changeset.Collection == Array2D <String, ListItemViewModel> {

        @objc func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
            return changeset?.collection[sectionAt: section].metadata
        }

and in viewDidload of your ViewController you must call this function.

private func setupViewModel() {  
        let sectionBindingDatSource: CustomSection = CustomSection<TreeChangeset>{ (changeset, indexPath, tableView) -> UITableViewCell in
            let cell = tableView.dequeueReusableCell(withIdentifier: String(describing: ListCell.self), for: indexPath) as! ListCell
            cell.item = changeset.sections[indexPath.section].items[indexPath.row]

            return cell
        }
        self.viewModel.sections.bind(to: self.tableView, using: sectionBindingDatSource)
    }

and if you want to override function of TableViewDataSourse and customize section you must set delegate

self.tableView.delegate = sectionBindingDatSource
