This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@olimpic245/react-native-directed-scrollview) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

react-native-directed-scrollview

demo

A natively implemented scrollview component which lets you specify different scroll directions for child content.

The iOS implementation extends the default UIScrollView component, whereas the Android implementation is custom and aims to provide some limited parity with the iOS api.

The following props are supported:

Prop	Default	Description
`scrollEnabled`	`true`	When false, the view cannot be scrolled via touch interaction.
`pinchGestureEnabled`	`true`	When true, ScrollView allows use of pinch gestures to zoom in and out.
`minimumZoomScale`	`1.0`	How far the content can zoom out.
`maximumZoomScale`	`1.0`	How far the content can zoom in.
`bounces`	`true`	Whether content bounces at the limits when scrolling.
`bouncesZoom`	`true`	Whether content bounces at the limits when zooming.
`alwaysBounceHorizontal`	`false`	When `bounces` is enabled, content will bounce horizontally even if the content is smaller than the bounds of the scroll view.
`alwaysBounceVertical`	`false`	When `bounces` is enabled, content will bounce vertically even if the content is smaller than the bounds of the scroll view..
ios `showsVerticalScrollIndicator`	`true`	Whether vertical scroll bars are visible.
ios `showsHorizontalScrollIndicator`	`true`	Whether horizontal scroll bars are visible.

The following methods are supported:

Method	Example	Description
`scrollTo`	`scrollTo({x: 100, y: 100, animated: true})`	Scrolls to a given x and y offset.

Installation

npm install react-native-directed-scrollview --save
react-native link (or rnpm link)

Usage

To work properly this component requires that a fixed-size content container be specified through the contentContainerStyle prop.

import ScrollView, { ScrollViewChild } from 'react-native-directed-scrollview';
...

export default class Example extends Component {
  render() {
    return (
      <ScrollView
        bounces={true}
        bouncesZoom={true}
        maximumZoomScale={2.0}
        minimumZoomScale={0.5}
        showsHorizontalScrollIndicator={false}
        showsVerticalScrollIndicator={false}
        contentContainerStyle={styles.contentContainer}
        style={styles.container}
      >
        <ScrollViewChild scrollDirection={'both'}>
          // multi-directional scrolling content here...
        </ScrollViewChild>
        <ScrollViewChild scrollDirection={'vertical'}>
          // vertically scrolling content here...
        </ScrollViewChild>
        <ScrollViewChild scrollDirection={'horizontal'}>
          // horizontally scrolling content here...
        </ScrollViewChild>
      </ScrollView>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
  },
  contentContainer: {
    height: 1000,
    width: 1000,
  },
})
