Parameters

region
CLRegion

The region to be monitored.

Attributes
ExportAttribute UnavailableAttribute IntroducedAttribute

Remarks

An application may monitor up to 20 uniquely-named (defined by Identifier) regions. The speed with which region notifications are delivered is dependent on network connectivity.

Region entry/exit notifications typically arrive within 3-5 minutes. Regions of less than 400m radius work better on iPhone 4S and later devices. (Notification speed seems fastest on devices with M7 coprocessors.)

Applies to

StartMonitoring(CLRegion, Double)

Starts monitoring the region.
