didHighlightRowAt in RxSwift

Question

How do I implement didHighlightRowAt (UITableViewDelegate) in RxSwift? I could find most of the delegate methods but I could not find didHighlightRowAt.

Answer 1

This way?

extension Reactive where Base: UITableView {

    var didHighlightRowAt: ControlEvent<IndexPath> {
        let selector = #selector(UITableViewDelegate.tableView(_:didHighlightRowAt:))
        let events = delegate
            .methodInvoked(selector)
            .filter({ ($0.last as? IndexPath) != nil })
            .map({ $0.last as! IndexPath })
        return ControlEvent(events: events)
    }
}

let observable = UITableView().rx.didHighlightRowAt.asObservable()
