LoadMoreTableViewController is a TableViewController that helps you to show some data like fetched from a web API successively.

LoadMoreTableViewController

Basic Usage

Prepare a Cell

You need to prepare a cell that is displayed on a LoadMoreTableViewController.

  • Xib file way

    1. Create a xib file then put a Table View Cell on it.
    2. Register the cell to the table of the LoadMoreTableViewController with using UITableView method register(_:forCellReuseIdentifier:).
      • The cellReuseIdentifier should be the same as the LoadMoreTableViewController property public var cellReuseIdentifier.
  • Storyboard way

    1. On a Storyboard, add a Table View Cell to a Table View Controller that inherits LoadMoreTableViewController.
    2. Set the Identifier of the Table View cell as it is the same as the LoadMoreTableViewController property public var cellReuseIdentifier.

The cell’s identifier should be the same as the LoadMoreTableViewController property public var cellReuseIdentifier on the both ways.
The default value is "Cell" and it is configureable.

The cell should be designed with using Auto Layout.
The LoadMoreTableViewController is using Automatic Dimension feature of UITableView so it will adjust the cell height.

Set Closures

  • public var fetchSourceObjects: (_ completion: @escaping (_ sourceObjects: [Any], _ hasNext: Bool) -> ()) -> ()

    • Fetch the new data in this closure.
    • Call completion closure to return these information.
      • The fetched new objects (sourceObjects).
      • If the next loading exists (hasNext).
  • public var configureCell: (_ cell: UITableViewCell, _ row: Int) -> UITableViewCell
    • Configure the cell and return it in this closure.
    • The cell type is the same as you prepared.

Example

import LoadMoreTableViewController

class MyTableViewController: LoadMoreTableViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        tableView.registerNib(UINib(nibName: "StandardCell", bundle: nil), forCellReuseIdentifier: cellReuseIdentifier)

        fetchSourceObjects = { [weak self] completion in
            self?.request(offset: sourceObjects.count) { products in
                completion(products, true)
            }
        }
        configureCell = { [weak self] cell, row in
            cell.textLabel?.text = (self?.sourceObjects[row] as? Product)?.title
            return cell
        }
    }

}

Additional Usage

Data Source

The fetched data are stored to the array public var sourceObjects: [Any].
You can directly access or manipulate this array.

Refreshing Data

Use function public func refreshData(immediately immediately: Bool).

  • immediately: true
    • Immediately makes the tableView empty and starts fetching the data from the first.
    • The loading activity indicator shows on the top.
  • immediately: false
    • Refreshes the tableView after fetching the data from the first.
    • This prevents the loading activity indicator is displayed on the top when UIRefreshControl is used.

Other Settings

  • public func showRetryButton()

    • Changes the loading activity indicator to retry button.
    • When retry button is tapped, next loading starts.
  • public static var retryText: String?

    • Changes retry button text.
  • public static var retryImage: UIImage?

    • Changes retry button image.
  • public var didSelectRow: ((Int) -> ())?
    • Notifies what row is selected.
