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:

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.
