Permission denied - geolocation in React Native

Question

I've been playing around with React Native, getting custom locations to work and setting the "NSLocationWhenInUseUsageDescription" key. The error, when running on the ios simulator, is this:

{
 "code": 2,
 "message": "Unable to retrieve location.",
 "PERMISSION_DENIED": 1,
 "POSITION_UNAVAILABLE": 2,
 "TIMEOUT": 3 
}

This is what I have, pretty much straight from the Geolocation example page https://facebook.github.io/react-native/docs/geolocation.html

/* eslint no-console: 0 */
'use strict';

var React = require('react');
var ReactNative = require('react-native');
var {
  StyleSheet,
  Text,
  View,
} = ReactNative;

export default class GeolocationExample extends React.Component {
  state = {
    initialPosition: 'unknown'
  };

  componentDidMount() {
    navigator.geolocation.getCurrentPosition(
      (position) => {
        var initialPosition = JSON.stringify(position);
        this.setState({initialPosition});
      },
      (error) => alert(JSON.stringify(error)),
      {enableHighAccuracy: true, timeout: 20000, maximumAge: 1000}
    );
  }

  render() {
    return (
      <View>
        <Text>
          <Text style={styles.title}>Initial position: </Text>
          {this.state.initialPosition}
        </Text>
      </View>
    );
  }
}

var styles = StyleSheet.create({
  title: {
    fontWeight: '500',
  },
});

Any help would be appreciated!

Answer 1

You need to set the location in the Simulator. There is an option for that in simulator menus as described in this question: Set the location in iPhone Simulator

Answer 2

In Simulator navigator, Choose Debug, at bottom choose Location, next choose Apple, then CMD+R to reload and it worked.

Answer 3

As Santosh suggested, you need to set the location in the iOS Simulator: Debug > Location.

Keep in my mind that from time to time, you will get the "PERMISSION_DENIED " error even tho you set the location in the simulator. If this is happening, you need to select a different predefined location and then the error goes away.
