how to retrieve all visible table section header views

Question

is there a way to get all the section header views that are visible?

something similar to UITableView\'s visibleCells instance method..

Answer 1

Swift 4+ Clean and simple, without duplicities:

extension UITableView {

    var visibleHeaderViews: [UITableViewHeaderFooterView] {
        guard let visibleSectionsIndexPaths = indexPathsForVisibleRows?.compactMap({ $0.section }) else { return [] }

        return Set(visibleSectionsIndexPaths).compactMap { headerView(forSection: $0) }
    }

}
