Question

I have a getLocation method that initializes my CLLocationManager and calls startUpdatingLocation. After I get the user’s location, I call stopUpdatingLocation.

Later, when the user presses refresh, I call a method reloadData which calls getLocation so I can get the user’s latest location. However, this never calls the locationManager:didUpdateToLocation:fromLocation
method.. so I never get the user’s latest location. What could be the issue?

-(void) getLocation {
self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.desiredAccuracy = kCLLocationAccuracyBest;
self.locationManager.delegate = self;
[self.locationManager startUpdatingLocation];
}

- (void) locationManager: (CLLocationManager *)manager 
 didUpdateToLocation: (CLLocation *)newLocation
        fromLocation:(CLLocation *)oldLocation
{
    if (oldLocation!= nil) { // make sure to wait until second latlong value
        [self setLatitude:newLocation.coordinate.latitude];
        [self setLongitude: newLocation.coordinate.longitude];
        [self.locationManager stopUpdatingLocation];
        self.locationManager.delegate = nil;
        self.locationManager = nil;
        [self makeUseOfLocationWithLat:[self getLatitude] andLon:[self getLongitude]];
    }
}

-(void) reloadData {
    [self getLocation];
}

Is it really necessary to allocate a new CLLocationManager? Try just allocate it once (in your init for example) and just call startUpdatingLocation and stopUpdatingLocation on demand.
For me, this solution works great.
