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)
}
}
