iOS Question

CLLocationManager always returns the exact same location

I am trying to set up a new CLLocation and CLRegion, but the location always returns with the same coordinates, regardless of where I actually am. My main UIViewController conforms to the CLLocationManagerDelegate protocol, as does a custom class. When the custom class initializes, I have a timer set to fire .25 seconds later, with this code:

mainLocationManager = [[CLLocationManager alloc] init];
[mainLocationManager startUpdatingLocation];
location = [mainLocationManager location];
if (![location.timestamp isEqualToDate:[NSDate dateWithTimeIntervalSinceNow:0]]) { //filters cached data by updating location if cached data not recent enough
location = [mainLocationManager location];
}

//Set up region
region = [[CLRegion alloc] initCircularRegionWithCenter:location.coordinate
radius:500
identifier:[NSString stringWithFormat:@"region:%@", locationName]];
NSLog(@"%@ %@", location, region);


The code appears to work except that the coordinate is always the same value. I am not sure how to change this. Any help is appreciated, thanks!

Answer

I think because you did not update location by location manager delegate method.

Get update location by this method

-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations

{
location_updated = [locations lastObject];    
NSLog(@"updated coordinate are %@",location_updated);

}

Also test it in device.
