Description

Provides details about an AGSGeotrigger condition that has been met.

An AGSGeotriggerNotificationInfo is sent by an AGSGeotriggerMonitor whenever the condition described by its AGSGeotrigger is met. The AGSGeotrigger also defines how the AGSGeotriggerNotificationInfo should be created. For example, it describes what message should be displayed to the user.

◆ actions

- (NSArray<NSString *>*) actions

readnonatomiccopy

An array of strings describing recommended actions based on this notification.

Optionally, use these strings to determine whether your app will perform custom behavior, such as showing messages or starting/stopping tracking. Note that there is no requirement to take any action when a notification is delivered, but these provide a way to understand the intention of the author of the AGSGeotrigger. This property can be empty.

These actions are the result of evaluating the AGSGeotrigger::messageExpression property for the specific objects that triggered this notification. If the expression returns a dictionary containing a list of strings with the key "actions", they are shown in this property.

For example, if the AGSGeotrigger::messageExpression property evaluates to a dictionary of AGSGeotriggerNotificationInfo::messageProperties containing the following key value pairs:

"message" with the string "Hello world"
"actions" with a list of action strings "startTracking"

then this property would contain "startTracking". The actions are simple strings, so you can use them to control any custom action for your app.

The author of an AGSGeotrigger can supply a set of all the possible AGSGeotrigger::requestedActions when defining the AGSGeotrigger. This property is an array of strings indicating the actions that should be taken by your app, based on this AGSGeotriggerNotificationInfo.

◆ feedEntityID

- (NSString*) feedEntityID

readnonatomiccopy

A unique ID for the entity within the feed that triggered the notification info.

This property is consistent for all notifications for a given feed entity. For example, use this ID to count the number of sites a team member visits.

If a feed is an AGSLocationGeotriggerFeed, all location updates for that feed share the same ID.

With an AGSFenceGeotrigger, you can combine this property with the AGSFenceGeotriggerNotificationInfo::fenceID property to create an ID that groups all notifications for a given feed entity and a specific fence. For example, use a concatenation of the two properties to display a list of areas of interest that are currently occupied and the details of who has entered them.

To group events by the geotrigger, use the AGSGeotrigger::geotriggerID property.

◆ feedLocation

- (AGSLocation*) feedLocation

readnonatomicstrong

An AGSLocation, received from the feed, that meets the AGSGeotriggerMonitor condition.

The AGSLocation is set if an AGSLocationGeotriggerFeed was used to create the AGSGeotrigger that the AGSGeotriggerMonitor is monitoring. This allows you to access the position and meta-data from the feed, such as the horizontal accuracy, velocity, time stamp and other AGSLocation::additionalSourceProperties.

◆ geotriggerMonitor

- (AGSGeotriggerMonitor*) geotriggerMonitor

readnonatomicstrong

The AGSGeotriggerMonitor that sent this notification.

The AGSGeotriggerMonitor evaluates a specific AGSGeotrigger condition that has been met by this AGSGeotriggerNotificationInfo. A single AGSGeotrigger condition can result in multiple, repeat notifications.

Use this property to interact directly with the AGSGeotriggerMonitor. For example, if you no longer want to receive future notifications, you can call stop (AGSGeotriggerMonitor).

◆ message

- (NSString*) message

readnonatomiccopy

A message that describes the notification.

The notification message is the result of evaluating the AGSGeotrigger::messageExpression for the specific objects that triggered this notification. The message could be a hard-coded string or use attributes from an area of interest that was entered to display a custom message.

For example, with an AGSFenceGeotrigger, setting the AGSGeotrigger::messageExpression property to:

"You have entered " + $fencefeature.area_name

would return the AGSGeotriggerNotificationInfo::message "You have entered Area A", where "area_name" is an attribute field on the AGSFenceGeotriggerNotificationInfo::fenceGeoElement.

You can use this message to alert the user directly or in other business logic in your app.

Since: 100.12

◆ messageProperties

- (NSDictionary<NSString *, id>*) messageProperties

readnonatomiccopy

A dictionary of optional properties derived from the AGSGeotrigger::messageExpression.

Optionally, you can evaluate the AGSArcadeExpression to produce properties on top of the basic AGSGeotriggerNotificationInfo::message. You can access this additional information via this dictionary.
