Add another 'UI' Library


License Platform Version


A custom stretchable header view for UIScrollView or any its subclasses with UIActivityIndicatorView support for reloading your content. Built for iOS 10 and later.


Example 1

Arale, by ZulwiyozaPutra

  • Compatible with UITableView, UICollectionView, or any UIScrollView subclasses.
  • Data source and delegate independency: can be added to an existing view controller without interfering with your existing delegate or dataSource.
  • No need to subclass a custom view controller or to use a custom UICollectionViewLayout.

If you are using this library in your project, I would be more than glad to know about it!


To add a stretchy header to your table or collection view, you just have to do this:

import Arale

init with optional backgroundImage

let araleHeaderView = AraleHeaderView(minHeight: 256.0, backgroundImage: myBackgroundImage)

In case you want to add a UIActivityIndicatorView, to handle action if the AraleHeaderView did resize to maxHeight you can implement a AraleHeaderViewDelegate conformed UIViewController

araleHeaderView.delegate = self

You can implement headerViewDidReachMaxHeight method to get event when the araleHeaderView did reach the maximum height

func headerViewDidReachMaxHeight(_ headerView: AraleHeaderView) {
    NSLog("%@", "Start Refreshing")

AraleHeaderViewDelegate comes with three optional delegate method

func headerViewWillResizeFrame(_ headerView: AraleHeaderView)
func headerViewDidResizeFrame(_ headerView: AraleHeaderView)
func headerViewDidReachMaxHeight(_ headerView: AraleHeaderView)


You can add an optional UIViewActivityIndicatorView in your stretchy header view:

let myActivityIndicatorview = UIActivityIndicatorView(style: .white)
araleHeadeView.activityIndicatorView = myActivityIndicatorView

the activityIndicatorView will not be rendered if remain nil in case you don't need an activityIndicator.


Arale is available through CocoaPods. To install it, simply add the following line to your Podfile, you can check the Example Podfile to see how it looks like:

pod "Arale"
