react-native-multi-picker-ios

This is simply a React Native bridge to UIMultiPicker iOS library.

Usage

API is very similar to React Native Picker:

import React from 'react'
import {
  AppRegistry, 
  StyleSheet, 
  SafeAreaView,
  Text
} from 'react-native'
import MultiPicker from 'react-native-ui-multi-picker'

class App extends React.Component {

  static TASTES = [
    'Sweet',
    'Sour',
    'Bitter',
    'Salty',
    'Umami'
  ];

  state = {
    selected: ['Sweet', 'Bitter']
  }

  render() {
    return (
      <SafeAreaView style={styles.container}>
        <MultiPicker
          style={styles.picker}
          onChange={({ selectedValues }) => this.setState({ selected: selectedValues })}
          selectedValues={this.state.selected}
        >{App.TASTES.map(taste => 
          <MultiPicker.Item key={taste} value={taste} label={taste} />)}
        </MultiPicker>
        <Text style={styles.caption}>Selected: {this.state.selected.join(', ')}</Text>
      </SafeAreaView>
    )
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1
  },
  picker: {
    backgroundColor: '#DDD'
  },
  caption: {
    padding: 20
  }
})

AppRegistry.registerComponent('App', () => App)

Installation

⚠️ This library relies on CocoaPods for proper dependency management, since it pulls native Swift library UIMultiPicker.

First:

npm install --save react-native-multi-picker-ios

Then add the following to your ios/Podfile:

pod 'RNMultiPicker', :path => '../node_modules/react-native-multi-picker-ios'

Finally run pod install.
