UILoadControl

UILoadControl is inspired by UIRefreshControl. It can be used to indicate data loading at the bottom of UITableView or UICollectionView.

Check this examples:

By default UIControl can only be placed as UITableView’s subview and it’s automatically handled as UIRefreshControl and placed at its top.

UILoadControl is a subclass of UIControl, placed inside a UIView (loadControlView) and this view is placed as a subview of UIScrollView. The UILoadControl has a UIScrollView extension (UIScrollView_Extesnion) that manage the UILoadControl’s layout.

All UIScrollView take the hability to handle UILoadControl in its .loadControl property.

Usage

To run the example project, clone the repo, and run pod install from the Example directory first.

Attach UILoadControl to any UIScrollView you want, like in the example below:

import UILoadControl

class MyViewController: UIViewController, UIScrollViewDelegate {
    
    var tableView: UITableView!
    
    //Setup loadControl on tableView
    override func viewDidLoad() {
        super.viewDidLoad()
        tableView.delegate = self
        tableView.dataSource = self
        tableView.loadControl = UILoadControl(target: self, action: #selector(loadMore(sender:)))
        tableView.loadControl?.heightLimit = 100.0 //The default is 80.0
    }
    
    //update loadControl when user scrolls de tableView
    func scrollViewDidScroll(_ scrollView: UIScrollView) {
        scrollView.loadControl?.update()
    }

    //load more tableView data
    func loadMore(sender: AnyObject?) {
        AnyAPIManager.defaultManager.giveMoreData() { (response, error) in
            //... Manage response
            self.tableView.loadControl?.endLoading() //Update UILoadControl frame to the new UIScrollView bottom.
            self.tableView.reloadData()
        }
    }
}

That’s it!
