CollectionSwipableCellExtension

It is the extension for UICollectionView and UITableView which appends buttons to a cell and shows them on cell swiping.

Features:

swipe to delete gesture
doesn’t require subclassing of cell class, it’s more useful in case when a third-party cell is already used.
the buttons UI are fully customised by providing own layout.
right-to-left languages support

Install

Carthage

github "KosyanMedia/CollectionSwipableCellExtension" ~> 0.0.1

Using

Initialize the extension object with UITableView or UICollectionView and set a delegate.
isEnabled property allows to activate/deactivate functionality.

swipableExtension = CollectionSwipableCellExtension(with: tableView)
swipableExtension?.delegate = self
swipableExtension?.isEnabled = true

Implement methods of CollectionSwipableCellExtensionDelegate protocol, which returns a layout for buttons and defines what cells are swipable.

func isSwipable(itemAt indexPath: IndexPath) -> Bool {
    return true
}

func swipableActionsLayout(forItemAt indexPath: IndexPath) -> CollectionSwipableCellLayout? {
    let actionLayout = CollectionSwipableCellOneButtonLayout(buttonWidth: 100, insets: .zero, direction: .leftToRight)
    actionLayout.action = { [weak self] in
        //do something
    }

    return actionLayout
}

Call resetSwipableActions() in UITableViewDelegate in order to exclude problems with cell's reuse.

func tableView(_ tableView: UITableView, didEndDisplaying cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    cell.resetSwipableActions()
}

or UICollectionViewDelegate

func collectionView(_ collectionView: UICollectionView, didEndDisplaying cell: UICollectionViewCell, forItemAt indexPath: IndexPath) {
    cell.resetSwipableActions()
}

Layout customization

We provide one simple layout CollectionSwipableCellOneButtonLayout. You can customize it by subclassing or create your own layout which implements CollectionSwipableCellLayout protocol.
