There are 2 properties on the CLLocation
-horizontalAccuracy
and -verticalAccuracy
. Most of times the accuracy is based on the hardware that you are using to get the location
Can I get the accuracy of GPS location in iOS?

Вопрос
I've seen Android developers get the accuracy of a GPS location. Is there a way that I can get the accuracy of my currenct GPS location in iOS?
I am using the code from this answer to get my location:
locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
locationManager.distanceFilter = kCLDistanceFilterNone;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
[locationManager startUpdatingLocation];
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {
NSLog(@"OldLocation %f %f", oldLocation.coordinate.latitude, oldLocation.coordinate.longitude);
NSLog(@"NewLocation %f %f", newLocation.coordinate.latitude, newLocation.coordinate.longitude);
}

horizontalAccuary
of CLLocation
gives the estimated positional error in meters related to the latitude, longitude coordinate.
verticalAccuracy
gives the estimated error related to altitude
.
Use horizontalAccuracy
and verticalAccuracy
properties in CLLocation
class. If horizontalAccuracy is a huge value you can discard the signals.
Also make sure to check the timeStamp
with current date to ensure that the GPS signal is not cached.
