Pulldown Refresh Demo

Check source code at Github:
https://github.com/Sylvia-YiyinShen/PulldownRefreshDemo

There are several different ways to implement pull-down refresh. One is based on scrollView delegate functions, another one is based on key-value observing on contentOffset. My demo is implemented via the later approach, since when applying the pull-down refreshing to a tableVIew it just requires 2-line changes.

• Easy to configure refresh control on existing tableView/collectionView
• Easy to replace the indicator(1-line change if using the indicator provided within the demo) https://github.com/Sylvia-YiyinShen/LoadingIndicatorDemo

How to use

• Grab Indicator and PulldownRefresh folder to your project
• Make your tableView subclassing RefreshableTableView
• Invoke RefreshableTableView func configureRefreshControl(refreshHandler: @escaping () -> Void)
• Invoke in the right place RefreshableTableView  func refreshDone()

Note: Look at the RefreshableTableView.swift if you also want to apply refreshControl to CollectionView
