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.

Usage

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


import Arale

var araleHeaderView: AraleHeaderView!

...

let araleHeaderView = AraleHeaderView(minHeight: 256.0, backgroundImage: myBackgroundImage)
araleHeaderView.delegate = self
self.tableView.addSubview(self.araleHeaderView)
...

// In case you want to add an UIActivityIndicatorView
// To handle action if the AraleHeaderView has resize to maxHeight you can implement a AraleHeaderViewDelegate conformed UIViewController

araleHeaderView.delegate = self

...

// And implement headerViewDidReachMaxHeight to get event when the araleHeaderView did reach the maximum height

func headerViewDidReachMaxHeight(headerView: AraleHeaderView) {
    NSLog("%@", "Start Refreshing")
    headerView.activityIndicatorView.stopAnimating()
}
...
// AraleHeaderViewDelegate comes with three optional delegate method
func headerViewWillResizeFrame(headerView: AraleHeaderView)
func headerViewDidResizeFrame(headerView: AraleHeaderView)
func headerViewDidReachMaxHeight(headerView: AraleHeaderView)
...

Configuration

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

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

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