React-native pull to refresh and pull-up load more component, supported custom refresh and load more component

Supported Scroll Component is:

• ScrollView
• ListView
• FlatList
• VirtualizedList

Supported React-Native Version is >= 0.43.0, because this lib supported FlatList

example is in the folder of example, the app.js is the entrance, example run in environment:

• expo: 23
• react-native: 0.50.0
• react: 16.0.0

Suggest: run example in real device, the performance will perfect

• cd example

• yarn install

• yarn start

and then take your iphone or android device, use the Expo app scan the QRCode, and have fun

Be careful:

• if can not load project, see the detail, sometimes it cost long time to load, and sometimes, the Expo version is incorrect
• checkout the network, whether is your device and your computer in the same network segment

$ npm install react-native-ptr-control --save

here is a simple usage of this lib, see example folder and find app.js for full usage

Note: when use react-native-ptr-control, use it as usual, for example, if scrollComponent is 'ScrollView', pass ScrollView`s props and props of lib provide, such as:

• ScrollView

    import React, {Component} from 'react'
    import {View, Text} from 'react-native'
    import PTRControl from 'react-native-ptr-control'
    export default class MyScrollComponent extends Component {
      render () {
        return (
          <PTRControl
            //here is the origin props of ScrollView
            style={{flex: 1}}
            showsVerticalScrollIndicator={false}
            //here is the props of lib provide
            scrollComponent={'ScrollView'}
            enableFooterInfinite={false}>
            <View>
              <Text>{'scroll content'}</Text>
            </View>
          </PTRControl>
          )
      }
    }
  

• ListView

    import React, {Component} from 'react'
    import {View, Text} from 'react-native'
    import PTRControl from 'react-native-ptr-control'
    export default class MyScrollComponent extends Component {
      render () {
        return (
          <PTRControl
            //here is the origin props of ListView
            dataSource={this.state.dataSource}
            renderRow={this.renderRow}
            showsVerticalScrollIndicator={false}
            //here is the props of lib provide
            scrollComponent={'ListView'}
            />
          )
      }
    }
  

Note: list of below props is extends props, the origin props of scroll component (for example: ScrollView) should also be passed

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

onHeaderRefreshing = {(gestureStatus, offset) => <HeaderRefresh gestureStatus={gestureStatus} offset={offset/>}

onFooterInfiniting = {(gestureStatus, offset) => <FooterInfinite gestureStatus={gestureStatus} offset={offset/>}

• 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

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

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
