Using the Maps SDK for iOS, you can customize the way in which users interact with your map, by determining which of the built in UI components appear on the map and which gestures are allowed.
Map controls
The Maps SDK for iOS provides some built-in UI controls that are
similar to those found in the Google Maps for iOS application. You can
toggle the visibility of these controls using the GMSUISettings
class.
Changes made on this class are immediately reflected on the map.
Compass
The Maps SDK for iOS provides a compass graphic which appears in the top right corner of the map under certain circumstances. The compass will only appear when the camera is oriented such that it has a non-zero bearing. When the user clicks on the compass, the camera animates back to a position with bearing of zero (the default orientation) and the compass fades away shortly afterwards.
The compass is disabled by default. You can enable the compass by setting the
compassButton
property of GMSUISettings
to YES
. However, you cannot
force the compass to always be shown.
Swift
let camera = GMSCameraPosition(latitude: 37.757815, longitude: -122.50764, zoom: 12) let mapView = GMSMapView(frame: .zero, camera: camera) mapView.settings.compassButton = true
Objective-C
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:37.757815 longitude:-122.50764 zoom:12]; GMSMapView *mapView = [GMSMapView mapWithFrame:CGRectZero camera:camera]; mapView.settings.compassButton = YES;
My Location button
The My Location button appears in the bottom right corner of the screen only
when the My Location button is enabled. When a user clicks the button, the
camera animates to focus on the user's current location if the user's location
is currently known. You can enable the button by setting the
myLocationButton
property of GMSUISettings
to YES
.
Swift
mapView.settings.myLocationButton = true
Objective-C
mapView.settings.myLocationButton = YES;
Floor picker
The floor picker control appears near the bottom right of the screen whenever an indoor map is featured prominently. When two or more indoor maps are visible the floor picker relates to the building nearest to the center of the screen. Each building has a default floor which is selected when the picker is first displayed. You can choose a different floor by selecting it from the picker.
You can disable the floor picker control by setting the indoorPicker
property
of GMSUISettings
to NO
.
Swift
mapView.settings.indoorPicker = false
Objective-C
mapView.settings.indoorPicker = NO;
Map gestures
You can disable the default gestures on the map by setting properties of the
GMSUISettings
class, which is available as a property of the GMSMapView
.
The following gestures can be enabled and disabled programmatically. Note that
disabling the gesture will not limit programmatic access to the camera
settings.
scrollGestures
— controls whether scroll gestures are enabled or disabled. If enabled, users may swipe to pan the camera.zoomGestures
— controls whether zoom gestures are enabled or disabled. If enabled, users may double tap, two-finger tap, or pinch to zoom the camera. Note that double tapping or pinching whenscrollGestures
are enabled may pan the camera to the specified point.tiltGestures
— controls whether tilt gestures are enabled or disabled. If enabled, users may use a two-finger vertical down or up swipe to tilt the camera.rotateGestures
— controls whether rotate gestures are enabled or disabled. If enabled, users may use a two-finger rotate gesture to rotate the camera.
In the example below, both pan and zoom gestures have been disabled.
Swift
override func loadView() { let camera = GMSCameraPosition.camera( withLatitude: 1.285, longitude: 103.848, zoom: 12 ) let mapView = GMSMapView.map(withFrame: .zero, camera: camera) mapView.settings.scrollGestures = false mapView.settings.zoomGestures = false self.view = mapView }
Objective-C
- (void)loadView { GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:1.285 longitude:103.848 zoom:12]; GMSMapView *mapView = [GMSMapView mapWithFrame:CGRectZero camera:camera]; mapView.settings.scrollGestures = NO; mapView.settings.zoomGestures = NO; self.view = mapView; }
