map - How to detect location is settled iphone sdk -

i have application gets users location , draws polyline on map. @ start app draws line on place (where gps trys gain accurate location). there way tell location accurate , hence start drawing.

i thought count , if statement after 5 location updates start- should user have strong location app fail.

any ideas?

check out cllocation objects passed cllocationmanagerdelegate's

locationmanager:didupdatetolocation:fromlocation

method; have, among other things, 2 properties available: horizontalaccuracy , verticalaccuracy.

they describe radius of error, measured in meters. http://developer.apple.com/library/ios/documentation/corelocation/reference/cllocation_class/cllocation/cllocation.html#//apple_ref/occ/instp/cllocation/horizontalaccuracy
