###中文介绍

ESPullToRefresh is an easy-to-use component that give pull-to-refresh and infinite-scrolling implemention for developers. By extension to UIScrollView, you can easily add pull-to-refresh and infinite-scrolling for any subclass of UIScrollView. If you want to customize its UI style, you just need conform the specified protocol.

Thanks to: SVPullToRefresh by Sam Vermette, EGOTableViewPullRefresh by enormego, these projects inspired me a lot.

self.tableView.es_addPullToRefresh {
	[weak self] in
	/// Do anything you want...
	/// ...
	/// Stop refresh when your job finished, it will reset refresh footer if completion is true

self.tableView.es_addInfiniteScrolling {
	[weak self] in
	/// Do anything you want...
	/// ...
	/// If common end
	self?.tableView.es_stopLoadingMore()
	/// If no more data

}

Customize Style

As effect:

PS: Load effect is from MeiTuan iOS app.

Customize refresh need conform the ESRefreshProtocol and ESRefreshAnimatorProtocol protocol.

Add customize pull-to-refresh

func es_addPullToRefresh(animator animator: protocol<ESRefreshProtocol, ESRefreshAnimatorProtocol>, handler: ESRefreshHandler)

Add customize infinite-scrolling

func es_addInfiniteScrolling(animator animator: protocol<ESRefreshProtocol, ESRefreshAnimatorProtocol>, handler: ESRefreshHandler)

Espried and auto refresh

ESPullToRefresh support for the latest expiration time and the cache refresh time, You need set an refreshIdentifier to your UIScrollView.

scrollView.refreshIdentifier = "Your Identifier" // Set refresh identifier
scrollView.expriedTimeInterval = 20.0 // Set the expiration interval

You can use es_autoPullToRefresh() method, when the time over the last refresh interval expires automatically refreshed.

scrollView.es_autoPullToRefresh()

let expried = scrollView.espried // expired or not
