cllocationmanager

For an app that does lots of calculation from the GPS, I need to get the latitude/longitude and speed every 0.5 second to be very accurate and avoid delay. I am using: [locationManager setDesiredAccuracy:kCLLocationAccuracyBestForNavigation]; - locationManager:didUpdateToLocation:fromLocation: function to store the value in 3 variables: newLatitude , newLongitude and newSpeed An NSTimer object that call a function every 0.5 second. See below a graph generated by Excel representing the latitude values during 18 seconds: We can clearly see that we have location updates every second, and not

Here is my VC code: import UIKit import MapKit import CoreLocation class ViewController: UIViewController, MKMapViewDelegate, CLLocationManagerDelegate { @IBOutlet weak var mapView: MKMapView! let locationManager = CLLocationManager() override func viewDidLoad() { super.viewDidLoad() locationManager.delegate = self locationManager.requestWhenInUseAuthorization() mapView.showsUserLocation = true } func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) { mapView.showsUserLocation = (status == .AuthorizedAlways) } func locationManager(manager:

I am working on Google Map Module , using 1.9.0 Bundle, to find my location on regular basis , say 10 seconds and create a button to get my location button as one of mapview settings When it comes to the execution and location service is turned on, there are no responses after clicking the right bottom button or not, the location manager is not working. I can show any signs of using location service. I am not sure what I am missing on setting this map as i follows strictly on the SDKDemos - ios google demo project to set my module. Would you please tell me the exact way to set it ? The

I have a very simple app example that initialises and updates the users location.. On device it successfully throws another callback location every second or so however on device (iPhone running iOS7) is calls the method once and then mysteriously stops... //Setup Location Manager in ViewDidLoad locationManager = [[CLLocationManager alloc] init]; [locationManager setDistanceFilter:kCLDistanceFilterNone]; [locationManager setDesiredAccuracy:kCLLocationAccuracyBest]; [locationManager setDelegate:self]; [locationManager startUpdatingLocation]; -(void)locationManager:(CLLocationManager *)manager

Problem : It seems I can't stop Core Location from sending updates to my app / tracking. What am I doing : In my viewWillAppear I call self.locationManager and pass it to a method to show user's location on the map (an instance of MKMapView ). The getter is overridden to check for availability of the serive, to see whether its authorized. If so, it allocs/inits and startMonitoringSignificantLocationChanges and returns . In viewDidDisappear , I call [self.locationManager stopUpdatingLocation] . But still I can see the location icon in the status bar. Even when I terminate the app by double

I've updated my iOS SDK to version 6. After that I've compiled my app (works fine in iOS 4 & iOS 5 ) but now the location services doesn't work. My delegate isn't receiving any update and the upper location arrow is not appearing... I'm starting the service as the usual way: [locationManager startUpdatingLocation]; My project is non ARC. What is happening? This is driving me crazy... Thanks in advance. Make sure you have a CFBundleDisplayName in your project's .plist file. Adding that key fixed it for me. Just set the property pausesLocationUpdatesAutomatically of Location Manager to NO . This

I am working on a piece of Swift code for iOS 8. I am trying to do something which involves location, and so i have implemented the following in my swift view controller file: let locationManger:CLLocationManager = CLLocationManager() var speedReceived:Double = 0 override func viewDidLoad() { super.viewDidLoad() locationManger.delegate = self locationManger.desiredAccuracy = kCLLocationAccuracyBest let authstate = CLLocationManager.authorizationStatus() if(authstate == CLAuthorizationStatus.NotDetermined){ println("Not Authorised") locationManger.requestWhenInUseAuthorization() } // Do any
