Installation

v1.5.14

$ npm i react-native-swiper --save

v1.6.0-rc

npm i --save react-native-swiper@next

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-swiper'

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

export default class SwiperComponent 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', () => SwiperComponent)

Supported ScrollResponder

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

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
$ yarn
$ yarn start
$ 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.

After development, you should add test for your modification and make all tests passed to prevent other contributors break the feature in the future accidentally. We use detox + jest for e2e test now, you can read Detox for more detail.
