Props
View props...
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.
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: number, longitude: number, latitudeDelta: number, longitudeDelta: number}
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.
showsUserLocation bool
If true the app will ask for the user's location and display it on the map. Default value is false.
NOTE: on iOS, you need to add the NSLocationWhenInUseUsageDescription key in Info.plist to enable geolocation, otherwise it will fail silently.
style View#style
Used to style and layout the MapView. See StyleSheet.js and ViewStylePropTypes.js for more info.
zoomEnabled bool
If false the user won't be able to pinch/zoom the map. Default value is true.
androidactive bool
iosannotations [{latitude: number, longitude: number, animateDrop: bool, draggable: bool, onDragStateChange: function, onFocus: function, onBlur: function, title: string, subtitle: string, leftCalloutView: element, rightCalloutView: element, detailCalloutView: element, tintColor: [object Object], image: Image.propTypes.source, view: element, id: string, hasLeftCallout: deprecatedPropType( React.PropTypes.bool, 'Use `leftCalloutView` instead.' ), hasRightCallout: deprecatedPropType( React.PropTypes.bool, 'Use `rightCalloutView` instead.' ), onLeftCalloutPress: deprecatedPropType( React.PropTypes.func, 'Use `leftCalloutView` instead.' ), onRightCalloutPress: deprecatedPropType( React.PropTypes.func, 'Use `rightCalloutView` instead.' )}]
Map annotations with title/subtitle.
iosfollowUserLocation 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.
ioslegalLabelInsets {top: number, left: number, bottom: number, right: number}
Insets for the map's legal label, originally at bottom left of the map. See EdgeInsetsPropType.js for more information.
iosmapType 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
iosmaxDelta number
Maximum size of area that can be displayed.
iosminDelta number
Minimum size of area that can be displayed.
iosoverlays [{coordinates: [object Object], lineWidth: number, strokeColor: [object Object], fillColor: [object Object], id: string}]
Map overlays
iosshowsCompass bool
If false compass won't be displayed on the map. Default value is true.
iosshowsPointsOfInterest bool
If false points of interest won't be displayed on the map. Default value is true.
