core-location

I'm currently developing an iPhone application which needs location services for various use including AR. I test everything on simulator and on my iPhone 3GS and everything went well. I recently tested on iPhone4 and on iPad2 and the location service (the little icon in status bar) keeps displaying even when I manually kill the app! The only way to disable this icon is to manually stop the location service for my app in the settings. Does anyone know something about this? If needed I can post my code. Thank you in advance Edit : When I kill the application, go to location services, switch off

I am trying to launch the maps app from my iPhone SDK app. Right now I can launch the maps app with directions but it goes to an overview of the directions and doesn't use Siri and the voice navigation to give turn by turn directions. currently I have a button that launches this code... NSString *address = viewedObject.addressFull; NSString *url = [NSString stringWithFormat: @"http://maps.apple.com/maps?saddr=%f,%f&daddr=%@", here.latitude, here.longitude, [address stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; [[UIApplication sharedApplication] openURL:[NSURL URLWithString

I have a problem keeping the GPS running in background. I succeded to keep the GPS running when the app is in background, but it stops sometimes. I noticed that it stops when i enter in a building and i stay there for 2-3 hours. "Stops" means that i don't receive any GPS point even though the location service icon is still on. Then when i get out i don't receive any points until I bring my application to foreground. I set the pausesLocationUpdatesAutomatically property to NO. So, everything works fine until i get into a location with weak gps signal. When i get out of that area i don't receive

The Cardcase application lets you know if you approach a shop which you have a previous relationship with (if you've set up a tab for payments there etc.). If background running applications cannot be started automatically on device boot, how does this app therefore work? Edited to make my question clearer: I am not asking how to monitor for location changes or how to monitor for location changes in the background. My question is, if the user install this app, then adds some tabs for some locations, then they reboot their iPhone, then how can this app subsequently notify them when they

An application I was testing asked for user location on first device launch. I have uninstalled the application, deleted the build folder, and cleaned all targets, but core location never requests permission again. It is just off and must be enabled in the users settings. Any idea why the users choice would remain persistent even after the application was uninstalled? Very weird behavior, worried it may get me rejected for the store. Not many people know this, but after you uninstall an application, that application's documents and preferences are still stored on the device, here: /var/mobile

Is it possible to determine programmatically that a user has denied permission to use their location? Secondly, if a user has denied permission, is it possible to re-prompt the user? You can determine your authorization status using the authorizationStatus class method on CLLocationManager . This returns a CLAuthorizationStatus which is defined as: typedef enum { kCLAuthorizationStatusNotDetermined = 0, kCLAuthorizationStatusRestricted, kCLAuthorizationStatusDenied, kCLAuthorizationStatusAuthorized } CLAuthorizationStatus; The system will prompt the user to authorize your application if the

Prior to iOS 4.0, CoreLocation was reporting altitude correctly, now it always reports as 0 ft. -(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation*)newLocation fromLocation:(CLLocation *)oldLocation { NSString *tLatitude = [NSString stringWithFormat:@"%3.5f", newLocation.coordinate.latitude]; NSString *tLongitude = [NSString stringWithFormat:@"%3.5f", newLocation.coordinate.longitude]; /* the following returns 0 */ NSString *tAltitude = [NSString stringWithFormat:@"%i", newLocation.altitude]; /* theres more code, but it's not relevant, and this worked prior to

We're told, via Apple's docs on startMonitoringSignificantLocationChanges that the following behavior can be expected by an application using the signification change API: If you start this service and your application is subsequently terminated, the system automatically relaunches the application into the background if a new event arrives. In such a case, the options dictionary passed to the locationManager:didUpdateLocations: method of your application delegate contains the key UIApplicationLaunchOptionsLocationKey to indicate that your application was launched because of a location event.

I'm trying to use some fancy iBeacons without success, kCLAuthorizationStatusNotDetermined all time. According to other questions it's a requirement to add those keys to info.plist (some questions says one, other says both). According to an article for iBeacons I need the Always option. <key>NSLocationWhenInUseUsageDescription</key> <string>Nothing to say</string> <key>NSLocationAlwaysUsageDescription</key> <string>Permiso para acceder siempre</string> At viewDidAppear: self.locManager = [[CLLocationManager alloc]init]; self.locManager.delegate = self; [self.locManager
