ReverseExtension

A UITableView extension that enables cell insertion from the bottom of a table view.

Concept

It is difficult to fill a tableview content from the bottom.

ReverseExtension rotates the UITableView and the UITableViewCells like in these images.

If you implement this logic in UIViewController, it will add too much complexity.

By encapsulating the implementation to the re namespace property, we hide the complexity.

In addition, you can roll back to the normal behavior by removing the re namespace.

Example

import UIKit
import ReverseExtension

class ViewController: UIViewController {
    @IBOutlet weak var tableView: UITableView!

    override func viewDidLoad() {
        super.viewDidLoad()
        tableView.dataSource = self
        tableView.register(UITableViewCell.self, forCellReuseIdentifier: "Cell")

        //You can apply reverse effect just by setting the delegate.
        tableView.re.delegate = self
        tableView.re.scrollViewDidReachTop = { scrollView in
            print("scrollViewDidReachTop")
        }
        tableView.re.scrollViewDidReachBottom = { scrollView in
            print("scrollViewDidReachBottom")
        }
    }
}

extension ViewController: UITableViewDelegate {
    //ReverseExtension also supports handling UITableViewDelegate.
    func scrollViewDidScroll(_ scrollView: UIScrollView) {
        print("scrollView.contentOffset.y =", scrollView.contentOffset.y)
    }
}
