Basic Usage

• Install react-native first

$ npm i react-native-cli -g

• Initialization of a react-native project

$ react-native init myproject

• Then, edit myproject/index.ios.js, like this:

import React, { Component } from 'react';
import {
  AppRegistry,
  StyleSheet,
  Text,
  View
} from 'react-native';

import Swiper from 'react-native-nextswiper';

const styles = StyleSheet.create({
  wrapper: {
  },
  slide1: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#9DD6EB',
  },
  slide2: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#97CAE5',
  },
  slide3: {
    flex: 1,

    alignItems: 'center',
    backgroundColor: '#92BBD9',
  },
  text: {
    color: '#fff',
    fontSize: 30,
    fontWeight: 'bold',
  }
})

export default class Swiper extends Component {
  render(){
    return (
      <Swiper style={styles.wrapper} showsButtons={true}>
        <View style={styles.slide1}>
          <Text style={styles.text}>Hello Swiper</Text>
        </View>
        <View style={styles.slide2}>
          <Text style={styles.text}>Beautiful</Text>
        </View>
        <View style={styles.slide3}>
          <Text style={styles.text}>And simple</Text>
        </View>
      </Swiper>
    );
  }
}

AppRegistry.registerComponent('myproject', () => Swiper);

Supported ScrollResponder

onTouchStartCapture	e / state / context	function	Immediately after onMomentumScrollEnd
onTouchStart	e / state / context	function	Same, but bubble phase
onTouchEnd	e / state / context	function	You could hold the touch start for a long time
onResponderRelease	e / state / context	function	When lifting up - you could pause forever before * lifting

Note: each ScrollResponder be injected with two params: state and context, you can get state and context(ref to swiper's this) from params, for example:

var swiper = React.createClass({
  _onMomentumScrollEnd: function (e, state, context) {
    console.log(state, context.state)
  },
  render: function() {
    return (
      <Swiper style={styles.wrapper}
      onMomentumScrollEnd ={this._onMomentumScrollEnd}
     ...
      </Swiper>
    )
  }
})

More ScrollResponder info, see: https://github.com/facebook/react-native/blob/master/Libraries/Components/ScrollResponder.js

Methods

scrollBy(index, animated)

Scroll by relative index.

Parameters:

Name	Type	default	Description
index	number	undefined	offset index
animated	bool	true	offset index

Examples

$ cd examples
$ npm i
$ react-native run-ios

Quick start with examples.

Development

$ cd examples
$ npm i
$ npm run dev
$ react-native run-ios

Then launch simulator to preview. Note that you just need to edit the source file src/index.js, the change will auto sync to examples.

And now that this project follows the standard code style, you'd better prepare it for IDE.
