   return (
   <PullScrollView
   renderItem={this.renderRow}
   data={this.state.dataSource}
   showsVerticalScrollIndicator={false}
   scrollComponent={'FlatList'}
   getRef={ref => this.refOfScrollList = ref}
   enableHeaderRefresh={true}
   onTopReachedThreshold={10}
   onHeaderRefreshing={() => {
   clearTimeout(this._timer)
   this._timer = setTimeout(() => {
   this.getData(true)
   this.setState({
   dataSource: this.data
   }, () => {
   PullScrollView.headerRefreshDone();
   })
   }, 1000)
   }}
   pullFriction={0.68}
   enableFooterInfinite={true}
   onEndReachedThreshold={10}
   onFooterInfiniting={() => {
   clearTimeout(this._timer)
   this._timer = setTimeout(() => {
   this.getData()
   this.setState({
   dataSource: this.data
   }, () => {

Properties

onHeaderRefreshing and onFooterInfiniting

this props should be passed a function, and gestureStatus and offset will be the params, something like that

onHeaderRefreshing = {(gestureStatus, offset) => }

onFooterInfiniting = {(gestureStatus, offset) => }

gestureStatus

0: gesture none 1: pull-up to load-more 2: pull-down to refresh 3: release to refresh or load-more 4: on header refreshing 5: on footer loading-more offset

when pull-down to refresh or pull-up to load-more, this offset params represent the pull distance static methods

Important: when header refresh done, or footer load-more done, should call this static method

headerRefreshDone PTRControl.headerRefreshDone()

after onHeaderRefreshing, when refresh done, and the data load complete, call this method to stop refresh

footerInfiniteDone PTRControl.footerInfiniteDone()

after onFooterInfiniting, when load-more done, and the data load complete, call this method to stop load-more
