core-location

Even my app is register for Location updates in background. In my code: self.locationManager.desiredAccuracy = kCLLocationAccuracyThreeKilometers; self.locationManager.distanceFilter = 2500; And I not moved anywhere. So after exactly 15 minutes in console log I got this message "Location icon should now be in state 'Inactive'" . From this point onwards my app is not running in background. It's happening in iPhone 5 only. @updated Here is my code self.locationManager = [[CLLocationManager alloc] init]; self.locationManager.delegate = self; [self.locationManager setPurpose:@"Enable Location

I know how to make this with NSTimer but I wan't to get current iPhone coordinates without timer on every few seconds. I can't use timer because I am getting coordinates while application is in background. I have tried something but this calls every second not every 10 seconds as I wan't. What am I doing wrong here? - (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations { CLLocation *loc = [locations objectAtIndex:0]; NSDate* eventDate = loc.timestamp; NSTimeInterval howRecent = [eventDate timeIntervalSinceNow]; if (howRecent < 10) { CLLocation* location =

I have MKMapView with MKUserTrackingModeFollowWithHeading. But something changes the userTrackingMode to MKUserTrackingModeFollow or None, so I implemented, - (void)mapView:(MKMapView *)mapView didChangeUserTrackingMode:(MKUserTrackingMode)mode animated:(BOOL)animated { if ([CLLocationManager locationServicesEnabled]) { if ([CLLocationManager headingAvailable]) { [self.myMapView setUserTrackingMode:MKUserTrackingModeFollowWithHeading animated:NO]; }else{ [self.myMapView setUserTrackingMode:MKUserTrackingModeFollow animated:NO]; } }else{ [self.myMapView setUserTrackingMode

I need to find out the number of routes from a source to a destination using the Google maps API, and then find, among those, which one is the shortest route. I am able to get one route by using this code -(NSArray*) calculateRoutesFrom:(CLLocationCoordinate2D) f to: (CLLocationCoordinate2D) t { NSString* saddr = [NSString stringWithFormat:@"%f,%f", f.latitude, f.longitude]; NSString* daddr = [NSString stringWithFormat:@"%f,%f", t.latitude, t.longitude]; NSString* apiUrlStr = [NSString stringWithFormat:@"http://maps.google.com/maps?output=dragdir&saddr=%@&daddr=%@", saddr, daddr]; NSURL*

I already have something that shows me my current speed and top speed (max speed in the code below) Now I want to make something that calculates my average speed with core location. How? thanks. - (void)locationUpdate:(CLLocation *)location { speedLabel.text = [NSString stringWithFormat:@"%.2f", [location speed]*2.236936284]; Here is the float for top speed float currentSpeed = [location speed]*2.236936284; if(currentSpeed - maxSpeed >= 0.01){ maxSpeed = currentSpeed; maxspeedlabel.text = [NSString stringWithFormat: @"%.2f", maxSpeed]; } Declare variable is your *.m class @implementation your
