IALocationManager Class Reference
Inherits from | NSObject |

Declared in | IALocationManager.h |
Overview
The IALocationManager class is central point for configuring the delivery of indoor location related events to your app. You use and instance of this class to establish the parameters that determine when location events should be delivered and to start and stop the actual delivery of those events. You can also use a location manager object to retrieve the most recent location data. The shared instance, property changes and methods of this class must be called from the application main thread only

distanceFilter
The minimum distance measured in meters that the device must move horizontally before an update event is generated. Default value is 0.7 meters. Uses CoreLocation CLLocationDistance.
@property (assign, nonatomic) CLLocationDistance distanceFilter
Declared In

The minimum angular change in degrees required to generate new didUpdateHeading event. Default value is 1 degree.
@property (assign, nonatomic) CLLocationDegrees headingFilter
Declared In

The minimum angular change in degrees required to generate new didUpdateAttitude event. Default value is 1 degree.
@property (assign, nonatomic) CLLocationDegrees attitudeFilter
Declared In
IALocationManager.h
desiredAccuracy
The accuracy of the location data.
@property (assign, nonatomic) enum ia_location_accuracy desiredAccuracy
Parameters
desiredAccuracy |
See possible values at ia_location_accuracy |
---|
Discussion
The receiver does its best to achieve the requested accuracy; however, the actual accuracy is not guaranteed. You should assign a value to this property that is appropriate for your usage scenario. Determining a location with greater accuracy requires more time and more power.
Default value is kIALocationAccuracyBest.
Declared In
IALocationManager.h
allowsBackgroundLocationUpdates
Explicitly enable background location updates. (iOS 9.0+ only)
@property (assign, nonatomic) BOOL allowsBackgroundLocationUpdates
Discussion
Location updates must be active when app goes to background for this flag to have effect. If you have enabled background execution in some other way, you may still receive location updates in background even if this flag is not set.
NOTE! you must also enable the Location updates background mode and include NSLocationAlwaysAndWhenInUseUsageDescription key in your app’s Info.plist file, and the user must authorize the always on background location permission in order for this flag to have any effect.
For more info, see: https://developer.apple.com/documentation/corelocation/getting_the_user_s_location/handling_location_events_in_the_background https://developer.apple.com/documentation/corelocation/cllocationmanager/1620568-allowsbackgroundlocationupdates https://developer.apple.com/documentation/corelocation/choosing_the_authorization_level_for_location_services/requesting_always_authorization
Default value is false, i.e. background location updates are not explicitly enabled
Declared In
IALocationManager.h
monitoredGeofences
The set of (dynamic) geofences monitored by the location manager. Note that automatically monitored cloud geofences are not included.
@property (nonatomic, readonly, strong, nullable) NSArray<IAGeofence*> *monitoredGeofences
Discussion
You cannot add geofences to this property directly. Instead use the <startMonitoringGeofence:> method.
Declared In

extraInfo
The latest extra information dictionary.
@property (nonatomic, readonly, nullable) NSDictionary *extraInfo
Discussion
Used for debugging positioning.

– lockFloor:
Locks positioning to specified floor level
- (void)lockFloor:(int)floorNumber
Parameters
floorNumber |
Floor level where the positioning is restricted |
---|
Declared In
IALocationManager.h
– unlockFloor
Unlocks positioning from locked floor. If lockFloor has not been called before, this is no-op.
- (void)unlockFloor
Declared In
IALocationManager.h
– lockIndoors:
Lock or unlock positioning indoors. Disables indoor-outdoor detection as well as GPS scanning if locked.

Parameters
lockIndoor |
boolean value indicating whether to lock or unlock indoor positioning |

key |
API key used for authentication. |

Discussion
This method must be called before further requests with server requiring authentication.

IALocationManager.h
– startUpdatingLocation
Starts the generation of updates that report the user’s current location.
- (void)startUpdatingLocation
Discussion
This method returns immediately. Calling this method causes the location manager to obtain an initial location fix (which may take several seconds) and notify your delegate by calling its <indoorLocationManager:didUpdateLocations:> method. After that, the receiver generates update events whenever there is new estimate.
Calling this method several times in succession does not automatically result in new events being generated. Calling stopUpdatingLocation in-between, however, does cause a new initial event to be sent the next time you call this method.
If you start this service and your app is suspended, the system stops the delivery of events until your app starts running again (only in foreground). If your app is terminated, the delivery of new location events stops altogether.
Declared In
IALocationManager.h
– stopUpdatingLocation
Stops the generation of location updates.
- (void)stopUpdatingLocation
Discussion
Call this method whenever your code no longer needs to receive location-related events. Disabling event delivery gives the receiver the option of disabling the appropriate hardware (and thereby saving power) when no clients need location data. You can always restart the generation of location updates by calling the startUpdatingLocation method again.
Declared In
IALocationManager.h
– startMonitoringForGeofence:
Starts monitoring the specified geofence. Note that cloud geofences are monitored automatically.
- (void)startMonitoringForGeofence:(nonnull IAGeofence *)geofence
Parameters
geofence |
The geofence object that defines the boundary to monitor. |
---|
Discussion
You must call this method once for each geofence you want to monitor. If an existing geofence with the same identifier is already being monitored by the app, the old geofence is replaced by the new one. Geofence events are delivered as regions to the <indoorLocationManager:didEnterRegion:> and <indoorLocationManager:didExitRegion:> methods of your delegate.
Declared In
IALocationManager.h
– stopMonitoringForGeofence:
Stops monitoring the specified geofence.
- (void)stopMonitoringForGeofence:(nonnull IAGeofence *)geofence
Parameters
geofence |
The geofence object currently being monitored. |
---|
Discussion
If the specified geofence object is not currently being monitored, this method has no effect.
Declared In
IALocationManager.h
– startMonitoringForWayfinding:
Start monitoring for wayfinding updates. Calling this method causes the location manager to obtain a route from user’s current location to destination defined in parameter “request” (this may take several seconds). Calling this method notify your delegate by calling its <indoorLocationManager:didUpdateRoute:> method. After that, the receiver generates update events whenever the route changes.
- (void)startMonitoringForWayfinding:(nonnull IAWayfindingRequest *)request
Parameters
request |
An IAWayfindingRequest specifying the type of wayfinding updates to monitor. |
---|
Discussion
Calling this method several times in succession overwrites the previously done requests. Calling stopUpdatingLocation in-between, however, does cause a new initial event to be sent the next time you call this method.
Declared In
IALocationManager.h
– stopMonitoringForWayfinding
Stops monitoring for wayfinding updates.
- (void)stopMonitoringForWayfinding
Discussion
Call this method whenever your code no longer needs to receive wayfinding route update events.
You can always restart the generation of wayfinding route updates by calling the
