ReverseExtension

UITableView extension that enabled to insert cell from bottom of tableView.

Concept

It is difficult to fill a tableview content from bottom. So, ReverseExtension rotate both of UITableView and UITableViewCell like this images.

If you implement those in ViewController, it will have been fat. So, escaping those implementation to re namespace property, and hiding those complex implementation. In addition, you can rollback to normal behaviour, only removing re namespace.

Example

import UIKit
import ReverseExtension

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

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

        //You can apply reverse effect only set 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)
    }
}
