Animated "Pull To Refresh" Library for UIScrollView.

You can add animated "pull to refresh" action to your UIScrollView, UITableView and UICollectionView.

Inspired by https://dribbble.com/shots/1797373-Pull-Down-To-Refresh

Xamarin.iOS version is here.

ScreenShot

Demo GIF Animation

You can play demo at appetize.io.

Installation

You can install this to your project via CocoaPods.

pod 'PullToBounce'

Usage

Please Wrap your scroll view

// Please wrap your scroll view
tableView.frame = yourFrame
let tableViewWrapper = PullToBounceWrapper(scrollView: tableView)

// Please add wrapper view to your view instead of your scroll view.
bodyView.addSubview(tableViewWrapper)

The frame of wrapper will be same as your scrollView.

And the color will be same as your scrollView's background color.

Event Handler

tableViewWrapper.didPullToRefresh = {
    didFinishYourLoading() {
        tableViewWrapper.stopLoadingAnimation()
    }
}

Custom Animation

Default arguments of "init" of PullToBounceWrapper

init(
  scrollView: UIScrollView, // this is the only required argument
  bounceDuration: CFTimeInterval = 0.8,
  ballSize:CGFloat = 36,
  ballMoveTimingFunc: CAMediaTimingFunction = CAMediaTimingFunction(controlPoints:0.49,0.13,0.29,1.61),
  moveUpDuration: CFTimeInterval = 0.25,
  pullDistance: CGFloat = 96,
  bendDistance: CGFloat = 40,
  didPullToRefresh: (()->())? = nil
)

You can use these arguments to customize animation.

You can’t perform that action at this time.
