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.
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!
