React Native Interface

LocationSwitch.enableLocationService(
    interval,
    requestHighAccuracy,
    successCallback,
    errorCallback
);

LocationSwitch.isLocationEnabled(
    successCallback,
    errorCallback
);

Option	Default	Info
interval	1000	Update interval in ms (ignored on IOS)
requestHighAccuracy	false	If true, highest accuracy is requested. If false, "block" level accuracy is requested (ignored on IOS)
successCallback	null	Is called when the user allows access to the location services or when the location services are already enabled
errorCallback	null	Is called when the user denies access to the location services

Usage

import React, { Component } from 'react';
import { AppRegistry, Text, View, TouchableOpacity, StyleSheet, Alert } from 'react-native';
import LocationSwitch from 'react-native-location-permission';

const style = StyleSheet.create({
  container: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'center',
  },
  button: {
    padding: 20,
  },
  text: {
    fontSize: 20,
  },
  textSuccess: {
    fontSize: 20,
    color: 'green',
  },
});

export default class LocationSwitchApp extends Component {

  constructor(props) {
    super(props);

    this.state = { locationEnabled: false };
    this.onEnableLocationPress = this.onEnableLocationPress.bind(this);
  }

  componentDidMount() {
    LocationSwitch.isLocationEnabled(
      () => {
        Alert.alert('Location is enabled');
        this.setState({ locationEnabled: true });
      },
      () => { Alert.alert('Location is disabled'); },
    );
  }

  onEnableLocationPress() {
    LocationSwitch.enableLocationService(1000, true,
      () => { this.setState({ locationEnabled: true }); },
      () => { this.setState({ locationEnabled: false }); },
    );
  }

  renderLocationStatus() {
    if (this.state.locationEnabled) {
      return <Text style={style.textSuccess} >Location enabled</Text>;
    }
    return <Text style={style.text}>Location disabled</Text>;
  }

  render() {
    return (
      <View style={style.container}>
        <TouchableOpacity style={style.button} onPress={this.onEnableLocationPress}>
          <Text style={style.text}>Enable location service</Text>
        </TouchableOpacity>
        {this.renderLocationStatus()}
      </View>
    );
  }
}

AppRegistry.registerComponent('reactClientSandbox', () => LocationSwitchApp);
