IALocationManagerDelegate Protocol Reference
Conforms to | NSObject |
---|---|
Declared in | IALocationManager.h |
Overview
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 thread in which you started the corresponding location services. That thread must itself have an active run loop, like the one found in your application’s main thread.
Responding to Location Events
– indoorLocationManager:didUpdateLocations:
Tells the delegate that new location data is available.
- (void)indoorLocationManager:(nonnull IALocationManager *)manager didUpdateLocations:(nonnull NSArray *)locations
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. |

Implementation of this method is optional but recommended.
