cllocationmanager

My app uses CLLocationManager to get location updates from the device. I had assumed that when the device was in Airplane Mode, I would not get location updates. But I do. The reason I assumed this is because Apple says that Airplane mode turns off Wifi, Cellular, Bluetooth, and GPS. See: http://support.apple.com/kb/ht1355 So, how is it that I'm getting a location update with a coordinate that seems reasonable? I've developed an app that heavily uses the user location, so I had to check this and other situations. I've learned that when all the services are off (Bluetooth, Wi-Fi, Cell Data)

After analysing location services in iOS 10, found that some inconsistency is in the caching behaviour. Fetching locations in a periodic time (in my case every 20 secs) returns locations but their timestamps are not in chronologically ordered. This indicates that the caching locations might have issues. So if you are checking accuracy through location-timestamp better to save the previous timestamps also. So that you could decide that the location fetched can be used or not. Below image is taken from my console log. Here I used the format "Lat Long : latitude_longitude | location_timestamp |

I have an array full of longitudes and latitudes. I have two double variables with my users location. I'd like to test the distance between my user's locations against my array to see which location is the closest. How do I do this? This will get the distance between 2 location but stuggeling to understand how I'd test it against an array of locations. CLLocation *startLocation = [[CLLocation alloc] initWithLatitude:userlatitude longitude:userlongitude]; CLLocation *endLocation = [[CLLocation alloc] initWithLatitude:annotation.coordinate.latitude longitude:annotation.coordinate.longitude];

In certain cases, cached values are immediately returned when starting a location service. Any location with a time interval older than this value will be considered invalid. @property (nonatomic, assign) NSTimeInterval maximumElapsedTimeForCachedLocation Declared In UABaseLocationProvider.h Do any of you know how to use this maximumElapsedTimeForCachedLocation in Core Location for removing the cache value of the old location? 来源： https://stackoverflow.com/questions/12909910/iphone-maximumelapsedtimeforcachedlocation-used-to-remove-cache-value-of-core-l

I'm using GMSMapView . So I added custom GMSMarker and set the image(Ex. Bike image) and animating that marker when user starts moving and changing the angle of the marker in locationManager . Currently I'm just updating position attribute of GMSMarker. But it gives the GMSMarker jump effect. Instead of this I want to move and rotate the GMSMarker smoothly/properly into the GMSMapView. How can i achieve this in Swift? Thanks. (void)updateLocationoordinates(CLLocationCoordinate2D) coordinates { if (marker == nil) { marker = [GMSMarker markerWithPosition:coordinates]; marker.icon = [UIImage

I want to receive location updates. I have added a location delegate to the header: @interface AppDelegate : UIResponder <UIApplicationDelegate, CLLocationManagerDelegate> and the following functions: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { //initialize location manager CLLocationManager* locationManager = [[CLLocationManager alloc] init]; locationManager.delegate = self; // [locationManager startMonitoringSignificantLocationChanges]; [locationManager startUpdatingLocation]; self.window = [[UIWindow alloc] initWithFrame:[
