MapView #

IMPORTANT: This component is now DEPRECATED and will be removed in January 2017 (React Native version 0.42). This component only supports iOS.

Please use react-native-maps by Airbnb instead of this component. Our friends at Airbnb have done an amazing job building a cross-platform MapView component that is more feature complete. It is used extensively (over 9k installs / month).

MapView is used to display embeddable maps and annotations using MKMapView.

import React, { Component } from 'react';
import { MapView } from 'react-native';

class MapMyRide extends Component {
  render() {
    return (
      <MapView
        style={{height: 200, margin: 40}}
        showsUserLocation={true}
      />
    );
  }
}

Props #

View props... #

annotations?: `[object Object]` #

Map annotations with title and subtitle.

followUserLocation?: `bool` #

If true the map will follow the user's location whenever it changes. Note that this has no effect unless showsUserLocation is enabled. Default value is true.

legalLabelInsets?: `{top: number, left: number, bottom: number, right: number}` #

Insets for the map's legal label, originally at bottom left of the map.

mapType?: `enum('standard', 'satellite', 'hybrid')` #

The map type to be displayed.

standard: Standard road map (default).
satellite: Satellite view.
hybrid: Satellite view with roads and points of interest overlaid.

maxDelta?: `number` #

Maximum size of the area that can be displayed.

minDelta?: `number` #

Minimum size of the area that can be displayed.

onAnnotationPress?: `function` #

Deprecated. Use annotation onFocus and onBlur instead.

onRegionChange?: `function` #

Callback that is called continuously when the user is dragging the map.

onRegionChangeComplete?: `function` #

Callback that is called once, when the user is done moving the map.

overlays?: `[object Object]` #

Map overlays

pitchEnabled?: `bool` #

When this property is set to true and a valid camera is associated with the map, the camera's pitch angle is used to tilt the plane of the map.

When this property is set to false, the camera's pitch angle is ignored and the map is always displayed as if the user is looking straight down onto it.

region?: `{latitude: [object Object], longitude: [object Object], latitudeDelta: [object Object], longitudeDelta: [object Object]}` #

The region to be displayed by the map.

The region is defined by the center coordinates and the span of coordinates to display.

rotateEnabled?: `bool` #

When this property is set to true and a valid camera is associated with the map, the camera's heading angle is used to rotate the plane of the map around its center point.

When this property is set to false, the camera's heading angle is ignored and the map is always oriented so that true north is situated at the top of the map view

scrollEnabled?: `bool` #

If false the user won't be able to change the map region being displayed. Default value is true.

showsAnnotationCallouts?: `bool` #

If true the map will show the callouts for all annotations without the user having to click on the annotation. Default value is false.

showsCompass?: `bool` #

If false, compass won't be displayed on the map. Default value is true.

showsPointsOfInterest?: `bool` #

If false points of interest won't be displayed on the map. Default value is true.

showsUserLocation?: `bool` #

If true the app will ask for the user's location and display it on the map. Default value is false.

NOTE: You'll need to add the NSLocationWhenInUseUsageDescription key in Info.plist to enable geolocation, otherwise it will fail silently.

style?: `[object Object]` #

Used to style and layout the MapView.

zoomEnabled?: `bool` #

If false the user won't be able to pinch/zoom the map. Default value is true.

androidactive?: `bool` #

Type Definitions #

AnnotationDragState #

State of an annotation on the map.

Type:
$Enum

Constants:

Value	Description
idle	Annotation is not being touched.
starting	Annotation dragging has began.
dragging	Annotation is being dragged.
canceling	Annotation dragging is being canceled.
ending	Annotation dragging has ended.
