Add refresh to UITableView(为UITableView添加header刷新和footer刷新)

// add header Refresh
mainTableView.xr.addPullToRefreshHeader(refreshHeader: XRActivityRefreshHeader(), heightForHeader: 65, ignoreTopHeight: XRRefreshMarcos.xr_StatusBarHeight) {
	// do request...
}

// add footer Refresh
mainTableView.xr.addPullToRefreshFooter(refreshFooter: XRActivityRefreshFooter(), refreshingClosure: {
	// do request...
})

Add refresh to UICollectionView(为UICollectionView添加header刷新和footer刷新)

// add header Refresh
mainCollectionVw.xr.addPullToRefreshHeader(refreshHeader: XRActivityRefreshHeader()) { 
	// do request...
}

// add footer Refresh
mainCollectionVw.xr.addPullToRefreshFooter(refreshFooter: XRActivityRefreshFooter(), refreshingClosure: {
	// do request...
})

Add refresh to UIWebView(为UIWebView添加header刷新扩展)

// add header Refresh
webView.xr.addPullToRefreshHeader(refreshHeader: XRActivityRefreshHeader()) { [weak self] in
	if let weakSelf = self {
	   weakSelf.webView.reload()
	}

}

Auto dropdown refresh(自定进行header下拉刷新)

mainTableView.xr.beginHeaderRefreshing()

End dropdown refresh(结束header刷新)

mainTableView.xr.endHeaderRefreshing()

Add a pull-up load(为UITableView，UICollectionView，UIWebView, WKWebView，UIScrollView添加刷新footer)

mainTableView.xr.addPullToLoadingMoreWithRefreshFooter(refreshFooter: XRActivityRefreshFooter(), heightForFooter: 55) {

	// do loading more request
}

End the pull up load more(结束footer刷新)

mainTableView.xr.endFooterRefreshing()

How to adapt iPhoneX, iPhoneXS, XR, and XS Max? (如何适配iPhone X...)

Very simple, you can specify the value of the ignoreTopHeight of XRRefreshHeader, and the value of ignoreBottomHeight of XRRefreshFooter, and ignoreBottomHeight is already adapted by default, no need to set, of course, you can also specify the value you want. Adaptation will become very simple.

非常简单，你可以指定 XRRefreshHeader的ignoreTopHeight, 以及 XRRefreshFooter的ignoreBottomHeight的值，而ignoreBottomHeight默认已经适配好了，无须设置，当然，你也可以指定你想要的值。适配将变得非常简单。

Rendering(效果图)

Customization(如何自定制刷新样式？)

You can inherit the base classes XRBaseRefreshHeader and XRBaseRefreshFooter, override refreshStateChanged, and, if necessary, override progressvaluechanged to customize the drop-down refresh and drop-down loading effects you want.

你可以通过继承 XRBaseRefreshHeader 和 XRBaseRefreshFooter这两个类，通过写很少的代码就可以自定制出你想要的下拉刷新，上拉加载样式，还可以通过 progressvaluechanged的值更精确得控制动画。

Under the hood(实现原理)

XREasyRefreshControl extends UIScrollView by adding new public methods as well as a dynamic properties.

It uses key-value observing to track the scrollView's contentOffset and contentSize.
