IALocationManagerDelegate

Objective-C

@protocol IALocationManagerDelegate <NSObject>

Swift

protocol IALocationManagerDelegate : NSObjectProtocol

The IALocationManagerDelegate protocol defines the methods used to receive location updates from an IALocationManager object.

Upon receiving a successful location update, you can use the result to update your user interface or perform other actions.

The methods of your delegate object are called from the main thread.

Responding to Location Events

  • Tells the delegate that new location data is available.

    Implementation of this method is optional but recommended.

    Declaration

    Objective-C

    - (void)indoorLocationManager:(nonnull IALocationManager *)manager
           didUpdateLocations:(nonnull NSArray *)locations;

    Swift

    optional func indoorLocationManager(_ manager: IALocationManager, didUpdateLocations locations: [Any])

    Parameters

    manager

    The location manager object that generated the update event.
    locations

    An array of IALocation objects containing the location data. This array always contains at least one object representing the current location. If updates were deferred or if multiple locations arrived before they could be delivered, the array may contain additional entries. The objects in the array are organized in the order in which they occured. Threfore, the most recent location update is at the end of the array.
