# react-native-swiper

  The original repository is no longer maintained, so i made this with some improvements:

- add missing type for **scrollViewStyle** (see this [PR]((https://github.com/leecade/react-native-swiper/pull/1304)))
- add **containerScrollViewStyle** prop for wrapper View that wraps ScrollView 


### Installation

```bash
$ npm i @ng-ha/react-native-swiper
```

### Basic Usage

- Install `react-native` first

```bash
$ npm i react-native-cli -g
```

- Initialization of a react-native project

```bash
$ react-native init myproject
```

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

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

import Swiper from '@ng-ha/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)
```

| bounces                          |  false  | `bool` | If `true`, the scroll view bounces when it reaches the end of the content if the content is larger then the scroll view along the axis of the scroll direction. If `false`, it disables all bouncing even if the alwaysBounce\* props are true. |
| scrollsToTop                     |  false  | `bool` | If true, the scroll view scrolls to top when the status bar is tapped.                                                                                                                                                                          |
| removeClippedSubviews            |  true   | `bool` | If true, offscreen child views (whose overflow value is hidden) are removed from their native backing superview when offscreen. This canimprove scrolling performance on long lists.                                                            |

#### Supported ScrollResponder

| Prop                |          Params           |    Type    | Description                                                 |
| :------------------ | :-----------------------: | :--------: | :---------------------------------------------------------- |
| onScrollBeginDrag   | `e` / `state` / `context` | `function` | When animation begins after letting up                      |
| onMomentumScrollEnd | `e` / `state` / `context` | `function` | Makes no sense why this occurs first during bounce          |
| 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:

```jsx
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>
    )
  }
})
```
