Map Extensions

Map Extensions

Have a look at our map extensions to make development more concise and pleasant.

Map UI Extensions

The iOS Maps SDK provides the following built-in UI views:

  • Compass button

  • Current location button

  • Panning controls

  • Zooming controls

You can toggle the visibility of these views using the UiSettings class. Changes made on this class are immediately reflected on the map. Each UI element has a predefined style that determines its position relative to the edge of the map. This style can be overridden to provide a custom position, adjust size, or replace default colors. It is also possible to alter these parameters in runtime by modifying the view’s LayoutParams.

Getting started

TTControlView class is a part of TomTomOnlieSDKMapsUIExtensions framework. To be able to use it, add this framework to Podfile as follows:

pod 'TomTomOnlineSDKMapsUIExtensions'

The next step is to add TTControlView on top of TTMapView with the same size, either through constraints or a frame, and then to make a relation between these views.

_

controlView.mapView = mapView
controlView.mapView = self.mapView;

 

Compass

By default, the compass button is enabled and located at the top left corner of the map: "MapView". The compass only appears when the map orientation is different than zero (‘North' position). When the user clicks on the compass button, the map orientation is set to zero and the compass disappears.

  • To disable the compass button:

_

controlView.compassButton?.isHidden = true
self.controlView.compassButton.hidden = YES;

 

  • To enable the compass button:

_

controlView.initDefaultCompassButton()
[self.controlView initDefaultCompassButton];

 

  • To override the default style:

_

controlView.setCompassButton(customCompassButton, withDefaultConstraints: true)
[self.controlView setCenterButton:customCompassButton withDefaultConstraints:YES];

 

Current location

By default, the current location button is enabled and placed in the bottom-left corner of the map: "MapView". The current location button appears only when the map center position on the screen is different from the user’s current location. When the user clicks the current location button, the map location is set to the user’s location and the button disappears. The default action for the button centers the map on the user’s location if "MapView" has been set up to show the current position on 'YES'.

  • To disable the current location button:

_

controlView.centerButton?.isHidden = true
self.controlView.centerButton.hidden = YES;

 

  • To enable the current location button:

_

controlView.initDefaultCenterButton()
[self.controlView initDefaultCenterButton];

 

  • To override the default style:

_

controlView.setCenter(customCurrentLocationButton, withDefaultConstraints: true)
[self.controlView setCenterButton:customCurrentLocationButton withDefaultConstraints:YES];

 

Panning controls

By default, the panning controls view is disabled and it is placed vertically in the center and horizontally on right-side of the map: "MapView". The default action for the view is to move the map in a desired direction.

Pan up

 

  • To enable the panning controls:

_

controlView.initDefaultTTPanControlView()
[self.controlView initDefaultTTPanControlView];

 

  • To disable the panning controls:

_

controlView.controlView?.isHidden = true
self.controlView.controlView.hidden = YES;

  * To override the default style:

_

controlView.controlView?.leftControlBtn = customControlLeftButton
self.controlView.controlView.leftControlBtn = customControlLeftButton;

 

Zooming controls

By default, the zooming controls view is disabled and it is placed vertically in the center and horizontally on right-side of the map: "MapView". The default action for the view is to zoom in or zoom out the map.

Zoom out

 

  • To enable the zooming controls:

_

controlView.initDefaultTTZoom()
[self.controlView initDefaultTTZoomView];

 

  • To disable the zooming controls:

_

controlView.zoomView?.isHidden = true
self.controlView.zoomView.hidden = YES;

 

  • To override the default style:

_

controlView.zoomView?.zoomIn = customControlZoomInButton
self.controlView.zoomView.zoomIn = customControlZoomInButton;

Static Map Image

Allow your user to render a user-defined rectangular image, containing a map section.

For more details, please visit Static Map Image documentation

Sample use case 1: Your app is designed to use simple map. You do not want to show the entire map, just some part of it to show and mark something simple. You don’t have to download the whole TomTomOnlineSDKMaps library which is much heavier compared to this library.

To use this library, add the following dependency to the Podfile file:

pod 'TomTomOnlineSDKMapsStaticImage'

Example of displaying static map:

_

let query = TTStaticImageQueryBuilder.withCenter(TTCoordinate.AMSTERDAM())
    .withLayer(.basic)
    .withStyle(.main)
    .withExt(.PNG)
    .withHeight(512)
    .withWidth(512)
    .build()
TTStaticImageQuery *query = [[[[[[[TTStaticImageQueryBuilder withCenter:[TTCoordinate AMSTERDAM]] withLayer:TTLayerTypeBasic] withStyle:TTStyleTypeMain] withExt:TTExtTypePNG] withHeight:512] withWidth:512] build];

Map Styles Extensions

The TomTom Maps SDK gives you the ability to use either online or offline styles in your mobile application.

  • If you choose to use offline styles, they will be imported to your app with the Maps SDK package. Thanks to that, the styles will already be included in your app at download time. The styles are added to the Maps SDK package by default.

  • If you choose to use online styles, they will be downloaded into your application when the map is displayed for the first time. Thanks to that, your mobile app size is smaller at the app’s download time so your app downloadable is lighter. In this case you need to exclude offline styles from the SDK.

Offline styles

To use the offline style framework, no actions are required because offline styles are attached to the map by default. To use the offline style library, no actions are required because offline styles are attached to the map by default i.e. the offline style framework 'TomTomOnlineSDKMapsStyle' will be added automatically while fetching 'TomTomOnlineSDKMaps'.

pod 'TomTomOnlineSDKMaps'

If offline styles are not attached to the project, nor online style is setup for the map, a black screen will render in mapView.

Online styles

To exclude offline styles from the TomTomOnlineSDKMaps framework, use an exclude declaration when the TomTomOnlineSDKMaps framework is declared as shown in the following code example.

pod 'TomTomOnlineSDKMaps/Online'

When offline styles are excluded, the online styles should be set up.

_

let mapStyleConfiguration = TTMapStyleDefaultConfiguration()
let mapConfig = TTMapConfigurationBuilder.create().withMapStyleConfiguration(mapStyleConfiguration).build()
let mapView = TTMapView(mapConfiguration: mapConfig)
TTMapStyleDefaultConfiguration *style = [[TTMapStyleDefaultConfiguration alloc] init];
TTMapConfiguration *config = [[[[[TTMapConfigurationBuilder createBuilder] withMapKey:Key.Map] withTrafficKey:Key.Traffic] withMapStyleConfiguration:style] build];
TTMapView *mapView = [[TTMapView alloc] initWithMapConfiguration:config];
self.view = mapView;
self.mapView = mapView;

 

You can set up online styles in TTMapView:

_

let mapStyleConfiguration = TTMapStyleConfiguration(styleURL: "<style json>")
let mapConfig = TTMapConfigurationBuilder.create().withMapStyleConfiguration(mapStyleConfiguration).build()
let mapView = TTMapView(mapConfiguration: mapConfig)
TTMapStyleConfiguration *mapStyleConfiguration = [[TTMapStyleConfiguration alloc] initWithStyleURL:@"<style json>"];    TTMapConfiguration *mapConfig = [[[TTMapConfigurationBuilder createBuilder] withMapStyleConfiguration:mapStyleConfiguration] build];
TTMapView *mapView = [[TTMapView alloc] initWithMapConfiguration:mapConfig];

 

Styling from source

You can use your offline style files in a similar manner to online hosted ones. You need just to pass a file path to the JSON file in your project as styleUrl.

Important
If you want to use style.json located in the main project catalog, use: "asset://../../style.json"
