iphone - Geo Fencing Identifier -


how specify entire country region in region identifier.wether accept the

identifier :@"uk"

here code reo identifier.how can specify england or uk.please me sort out

cllocationcoordinate2d location2d = mapview.region.center;  clregion *regionformonitoring = [[clregion alloc] initcircularregionwithcenter:location2d radius:1 identifier:@"regionidentifier"]; [[utils getlocationmanager] startmonitoringforregion:regionformonitoring];

clregions totally unsuitable purpose.

first of all, radius specified distance in meters region covers - in case asking system monitor region @ specific lat/long radius of 1 meter!

also, system regions have maximum number of regions can monitored (around 10 or so), , maximum radius can used of around 400 meters after region not work.

you need read "monitoring shape based regions" section of apple document:

http://developer.apple.com/library/ios/#documentation/userexperience/conceptual/locationawarenesspg/corelocation/corelocation.html

there 2 other possible approaches trying do:

1) use significant location updates, , test on each update if in area shape specify.

2) use coretelephony cell carrier device on , see if carrier number matches 1 in country of interest. of course, not work on ipads or other ios devices no cell connection.

neither of approaches exact around edges, not consume battery life using gps.
