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

override func viewDidLoad() {
    super.viewDidLoad()
    let newLoadControl = UILoadControl()
    newLoadControl.heightLimit = 100.0 //The default is 80.0
    newLoadControl.addTarget(self, action: "loadMoreData:", forControlEvents: UIControlEvents.ValueChanged)
    self.tableView.loadControl = newLoadControl
}

func loadMoreData(sender: AnyObject?) {
    //intentional Delay that represents a Network asyc call...
    let delaySeconds = 4
    let delayTime = dispatch_time(DISPATCH_TIME_NOW, Int64(delaySeconds * Double(NSEC_PER_SEC)))
    dispatch_after(delayTime, dispatch_get_main_queue()) {
      self.tableView.loadControl!.endLoading() //Update UILoadControl frame to the new UIScrollView bottom.
      self.tableView.reloadData()
    }
  }
}

That's it!
