UITableViewRowAction example in Swift

This Swift code example will demonstrate how to user UITableViewRowAction to add Table View Row Action Buttons to UITableView.

The code example below will cover:

  • Implement UITableView programmatically
  • User UITableViewDataSource and UITableViewDelegate protocols to load data into table view and make table row cells interactive
  • Load three items from an array into the table view
  • Determine device screen size and make table view stretch full width and height
  • Implement editActionsForRowAtIndexPath to make table view cell slide to the left side and reveal action buttons
  • User UITableViewRowAction to create two table view row action buttons
  • Handle events when user taps on UITableViewRowAction button
  • Change background color of UITableViewRowAction
  • Use UIAlertController to display an Action Sheet when user taps on share action button
  • Handle events when user taps on UIAlertController action buttons

UITableViewRowAction. Add Table View Row Action Buttons to UITableView

  func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [UITableViewRowAction]?
    {
        let shareAction  = UITableViewRowAction(style: .Normal, title: "Share") { (rowAction, indexPath) in
            print("Share Button tapped. Row item value = \(self.itemsToLoad[indexPath.row])")
            
            self.displayShareSheet(indexPath)
        }
        let deleteAction  = UITableViewRowAction(style: .Default, title: "Delete") { (rowAction, indexPath) in
            print("Delete Button tapped. Row item value = \(self.itemsToLoad[indexPath.row])")
        }
        shareAction.backgroundColor = UIColor.greenColor()
        return [shareAction,deleteAction]
    }
