iOS Runtime SDK AGSLocation.lastKnown Value

Question

Why this lastKnown boolean value always return false, may i know the AGSLocation should inform to the location as true or false for the readonly property called lastKnown.

When lastKnown is true, it means the location data may have been queued up or deferred by the data source. If lastKnown is false, this means that the location data is current. See the documentation on AGSLocation.lastKnown: Indicates whether the location information is current or based on a last known update (for example, in the case of deferred location updates). Last known locations are symbolized differently using AGSLocationDisplay::acquiringSymbol.
