core-location

I am creating an app that tells the user whether they are near the destination. I am calculating the distance between the currentLocation and the destination. I'm doing the calculation inside the didUpdateLocations . It is working but I've seen that there are methods that can deal with that without the need of doing any math. I am registering the region in the CLLocationManager ; however it seems that the methods didExitRegion and didEnterRegion are not been called. Here are the part of the code where I register the region: - (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar { [self

My purpose is to get the longitude/latitude of the user when the view is loaded and to store the values in two variables for later calculations. I don't need to track the user location and to update it, I simply need to get his/her coordinates once . My code looks like this: - (void)viewDidLoad { [super viewDidLoad]; // locationManager update as location locationManager = [[CLLocationManager alloc] init]; locationManager.delegate = self; locationManager.desiredAccuracy = kCLLocationAccuracyBest; locationManager.distanceFilter = kCLDistanceFilterNone; [locationManager startUpdatingLocation];

I have background mode on for location services and aiming to send out location (latitude and longitude) to the server every 30 minutes. For now I am printing the same in the console. It seems to work for a while but I am wondering how do I work with NSTimer in this case. And from where should I be calling it? import UIKit import CoreLocation @UIApplicationMain class AppDelegate: UIResponder, UIApplicationDelegate, CLLocationManagerDelegate { var window: UIWindow? var locationManager = CLLocationManager() func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions:

I have an app that uses a combination of startMonitoringForRegion: and startMonitoringSignificantLocationChanges to keep aware of where the user is when the app is in the background. Does this mean that I need to include the location value for the UIBackgroundModes key in the Info.plist ? This is a quote from the docs: The significant-change location service is highly recommended for apps that do not need high-precision location data. With this service, location updates are generated only when the user’s location changes significantly; thus, it is ideal for social apps or apps that provide the

I would like to get the blue bar when tracking in the background, but not when not. My app uses location services all the time when active, so in iOS8 I use the requestWhenInUseAuthorization on CLLocationManager . Normally, the app stops tracking your location when you close it, but the user can choose the option to let the app track his location in the background as well. Therefore, I have the location option for UIBackgroundModes in the Info.plist file. That works perfectly: when switching to the background, the app keeps getting location updates, and a blue bar appears as a reminder that
