Instance Property


The largest boundary distance that can be assigned to a region.


@property(readonly, nonatomic) CLLocationDistance maximumRegionMonitoringDistance;


This property defines the largest boundary distance allowed from a region’s center point. Attempting to monitor a region with a distance larger than this value causes the location manager to send a kCLErrorRegionMonitoringFailure error to the delegate.

If region monitoring is unavailable or not supported, the value in this property is -1.
