in iOS8 when i m putting my app in back ground the CLLocationManager returns Null in location ,i have also unable Location updates in Background Modes and also do requestAlwaysAuthorization
CLLocationManager *lm = [[CLLocationManager alloc] init];
lm.delegate = self;
lm.desiredAccuracy = kCLLocationAccuracyBest;
lm.distanceFilter = kCLDistanceFilterNone;
[lm requestAlwaysAuthorization];
[lm startUpdatingLocation];
Please find below code for getting location on background mode -
Please enter text for NSLocationAlwaysUsageDescription in plist file .
Please select location updates on background mode from project settings -

Hope this will help you
do put code in viewDidLoad about CLLocationManger
CLLocationManager *lm = [[CLLocationManager alloc] init];
lm.delegate = self;
lm.desiredAccuracy = kCLLocationAccuracyBest;
lm.distanceFilter = kCLDistanceFilterNone;
[lm requestAlwaysAuthorization];
[lm startUpdatingLocation];
Problem solved..

This question already has answers here:
How to find your current location with CoreLocation
(3 answers)
Closed 6 years ago.
I am working in google map in my app. i get default location on map currently. but i need to get current location of device an show it on map. There are lots of solution are there on stackoverlfow, but somehow its not working in my case. These solution work if i add map on default view.Look at my little bit code.
.h file
#import <UIKit/UIKit.h>
#import <CoreLocation/CoreLocation.h>
#import GoogleMaps;
#interface ViewController : UIViewController<CLLocationManagerDelegate, GMSMapViewDelegate>
#property (weak, nonatomic) IBOutlet UIView *maponScreem;
#property (nonatomic, retain) CLLocationManager *locationManager;
#end
.m file
self.locationManager.delegate = self;
self.locationManager = [[CLLocationManager alloc] init];
self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.distanceFilter = kCLDistanceFilterNone;
self.locationManager.desiredAccuracy = kCLLocationAccuracyHundredMeters; // 100 m
[self.locationManager startUpdatingLocation];
latitude = [NSString stringWithFormat:#"%f",self.locationManager.location.coordinate.latitude];
longtitude = [NSString stringWithFormat:#"%f",self.locationManager.location.coordinate.longitude];
NSLog(#"%#", latitude);
NSLog(#"%#", longtitude);
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:[latitude floatValue]
longitude:[longtitude floatValue]
zoom:12];
mapView_ = [GMSMapView mapWithFrame:self.maponScreem.bounds camera:camera];
mapView_.delegate = self;
mapView_.myLocationEnabled = YES;
[self.maponScreem addSubview: self->mapView_];
// Creates a marker in the center of the map.
GMSMarker *marker = [[GMSMarker alloc] init];
marker.position = CLLocationCoordinate2DMake([latitude intValue], [longtitude intValue]);
marker.title = #"Current Location";
marker.map = mapView_;
i get 0.000000 for attitude and longitude.
EDIT:
i found solution and look at this how it works. Thanks to you all for answers and support me.
- (void)viewDidLoad {
[super viewDidLoad];
if (self.locationManager == nil)
{
self.locationManager = [[CLLocationManager alloc] init];

// NSLog(#"%#", lat);
// NSLog(#"%#", longi);
[mapView_ animateToLocation:location.coordinate];
}
You have not initialized your locationManager and also you need to ask user permission for location access and set its delegate.Use following code before starting location updates.
self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.delegate = self;
if ([self.locationManager respondsToSelector:#selector(requestWhenInUseAuthorization)]) {
[self.locationManager requestWhenInUseAuthorization]; //gives alert for location access
}
It will give you user location.
Hope it helps :)
EDIT
You should use below method to receive location updates
- (void)locationManager:(CLLocationManager *)manager
didUpdateLocations:(NSArray<CLLocation *> *)locations
The method you have used is deprecated.
#property (nonatomic, retain) IBOutlet GMSMapView *googleMapView;
#property (nonatomic, retain) CLLocationManager *locationManager;
- (void)showCurrentLocation {
_googleMapView.myLocationEnabled = YES;
[self.locationManager startUpdatingLocation];
}
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:newLocation.coordinate.latitude
longitude:newLocation.coordinate.longitude
zoom:17.0];
[_googleMapView animateToCameraPosition:camera];
//...
}
I hope this will help you..
- (IBAction)btnSetDistance:(id)sender {
locationManager.delegate = self;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
locationManager.pausesLocationUpdatesAutomatically = NO;
locationManager.distanceFilter =//as per your requirment;
if ([locationManager respondsToSelector:#selector(requestWhenInUseAuthorization)]) {
[locationManager requestWhenInUseAuthorization];
}
[locationManager startUpdatingLocation];
}
This is important
Enable Background Modes from--- Project, Capabilities Tab, and choose Location Updates...
you should check it on device instead of simulator.
I wonder how to capture the location when the app is not running and save the database. Already followed several tutorials but none worked. Please, before scoring as duplicate, I ask you to read the complete question as it can not be.
I tried the following tutorials:
Getting Location Updates for iOS 7 and 8 when the App is Killed/Terminated/Suspended
Background Modes Tutorial: Getting Started
to run app continously in the background
Not exactly what I need, but still I tried
Assuming that I have no implementation for the capture location. I need every day at noon, capture the user's location and save the database then send to a web service.
This capture location must be made regardless of whether the app is active in the background or not running (two rings on the middle button and dragging).
I tried some tutorials found on the internet and even some suggested here by the community, but still rather not worked.
I have added background modes - Location.
I allowed to get location requestAlwaysAuthorization.
The language can be in objective-c or swift, Most importantly, I learn how to capture this location when app in all states.
OK i am going to make this as simple as possible..Enable Background Modes and tick background fetch like this
Follow this methods for every step
When app is TERMINATED
AppDelegate.h
#import <UIKit/UIKit.h>
#import <CoreLocation/CoreLocation.h>
#interface AppDelegate : UIResponder <UIApplicationDelegate,CLLocationManagerDelegate>
#property (strong, nonatomic) UIWindow *window;
#property (strong,nonatomic) CLLocationManager *locationManager;

#import "AFNetworking.h"
#import <GoogleMaps/GoogleMaps.h>
#implementation AppDelegate{
BOOL fromTerminated;
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
fromTerminated = NO;
if ([launchOptions objectForKey:UIApplicationLaunchOptionsLocationKey]) {
fromTerminated = YES;
self.locationManager = [[CLLocationManager alloc]init];
self.locationManager.delegate = self;
self.locationManager.desiredAccuracy = kCLLocationAccuracyBestForNavigation;
self.locationManager.activityType = CLActivityTypeOtherNavigation;
[self.locationManager startUpdatingLocation];
}
return YES;
}
- (void)applicationDidBecomeActive:(UIApplication *)application {
if(self.locationManager){
[self.locationManager stopMonitoringSignificantLocationChanges];
self.locationManager = nil;
self.locationManager.delegate = nil;
}
self.locationManager = [[CLLocationManager alloc]init];
self.locationManager.delegate = self;
self.locationManager.desiredAccuracy = kCLLocationAccuracyBestForNavigation;
self.locationManager.activityType = CLActivityTypeOtherNavigation;
if(IS_OS_8_OR_LATER) {
[self.locationManager requestAlwaysAuthorization];
}
[self.locationManager startMonitoringSignificantLocationChanges];
}
-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations{
NSLog(#"locationManager didUpdateLocations: %#",locations);
if(fromTerminated){
CLLocation * newLocation = [locations lastObject];
CLLocationCoordinate2D theLocation = newLocation.coordinate;
CLLocationAccuracy theAccuracy = newLocation.horizontalAccuracy;
[userDef setObject:[NSString stringWithFormat:#"%f",theLocation.longitude] forKey:#"LONGITUDE"];
[userDef setObject:[NSString stringWithFormat:#"%f",theLocation.latitude] forKey:#"LATITUDE"];
self.myLocation = theLocation;
self.myLocationAccuracy = theAccuracy;
[self updateLocation];
}
}
-(void)updateLocation{
// call your webservice for updating
}
#end
This code will do the following-->
Background fetch will trigger a location change and will launch the application and didFInishLaunchingWithOptions will be called with a UIApplicationLaunchOptionsLocationKey in the option dictionary. If it finds this that means the application is TERMINATED and woke up for background fetch. Now you got 30 seconds or so to do your stuff. So you create a location manager object and start updating, which will trigger your didUpdateLocations delegate method and then you can call your method to trigger that changed location in your server or database.
In your normal VC create another Location Manager object just like you created in the didFinishiLaunchingWithOptions method and implement the delegate method didUpdateLocation this will run untill the application is in foreground or background. The app delegate method hack will trigger the application when its terminated.
Cheers :)

case kCLAuthorizationStatusAuthorizedWhenInUse:
case kCLAuthorizationStatusAuthorizedAlways: {

} break;

break;
}
}
#end
[EDIT]
TO check that app is getting launched after terminated state do this change and hit the run button and change the location of the device from the storyboard
Do this change, and Run the project (Do this in debug mode of a device)
and change location by this and then stick a breakpoint in applicationDidFinishLaunchingWithOptions and you will see the breakpoint is hit, meaning the app was in terminated state but this location change has triggered the OS to launch the application.
Hope could make you understand
In iOS 8.3 with xCode 6.3.2, when I'm launching Map, it throws the following error:
Trying to start MapKit location updates without prompting for location authorization. Must call -[CLLocationManager requestWhenInUseAuthorization] or -[CLLocationManager requestAlwaysAuthorization] first.
I have done everything and follow every step to launch a map in ios8 app, here is my code for this:
//viewcontroller default function set mapview and a function to find user current location.
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
[[self otlMapView] setShowsUserLocation:YES];
self.otlMapView.delegate = self;
[self updateUserCurrentLocation];
}
//this function is used to fine the user current location.
-(void)updateUserCurrentLocation
{
// Create a location manager
self.locationManager = [[CLLocationManager alloc] init];
// Set a delegate to receive location callbacks
self.locationManager.delegate = self;
self.locationManager.desiredAccuracy = kCLLocationAccuracyBest;
if ([self.locationManager respondsToSelector:#selector(requestWhenInUseAuthorization)])
{
[self.locationManager requestWhenInUseAuthorization];
}
// Start the location manager
[self.locationManager startUpdatingLocation];
[self.locationManager requestWhenInUseAuthorization];
}
#pragma mark Location Callback Method
// Wait for location callbacks
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
NSLog(#"Current Location%#", [locations lastObject]);
}
What am I doing wrong?
You should make sure to call
[self.locationManager requestWhenInUseAuthorization];
before calling
[self.locationManager startUpdatingLocation];
Also, have you set up your Info.plist?
I assume you've correctly set up your Info.plist already. Then try something like this:
- (void)viewDidLoad {
[self updateUserCurrentLocation];
}
- (void)updateUserCurrentLocation {
if (nil == locationManager) {
locationManager = [[CLLocationManager alloc] init];
}
locationManager.delegate = self;
// This part was added due to a location authorization issue on iOS8
// See more at: http://nevan.net/2014/09/core-location-manager-changes-in-ios-8/
if ([self._locationManager respondsToSelector:#selector(requestWhenInUseAuthorization)]) {
[self._locationManager requestWhenInUseAuthorization];
}
self.mapView.showsUserLocation = YES;
[locationManager startUpdatingLocation];
CLLocation *currentLocation = locationManager.location;
if (currentLocation) {
PAWAppDelegate *appDelegate = [[UIApplication sharedApplication] delegate];
appDelegate.currentLocation = currentLocation;
}
}
Check if you have this key in your info.plist,
"Privacy - Location Usage Description",
if yes remove this and retain the "When in use" key. it should then work.
I have been trying to get the current location IOS8 and following thread Location Services not working in iOS 8 but getting the 00.00,00.00 instead current location. Any suggestion on where I am doing wrong.

I have also added the following key in my info.plist
<key>NSLocationAlwaysUsageDescription</key>
<string>Your location is needed for this app.</string>
Add this string in InfoPlist.strings files
1) NSLocationWhenInUseUsageDescription
2) NSLocationAlwaysUsageDescription
Try this code
locationManagerApp=[[CLLocationManager alloc] init];
locationManagerApp.delegate = self;
locationManagerApp.distanceFilter = kCLDistanceFilterNone;
locationManagerApp.desiredAccuracy = kCLLocationAccuracyHundredMeters;
if([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
{
[locationManagerApp requestAlwaysAuthorization];
}
[locationManagerApp startUpdatingLocation];
CLLocation *location1 = [locationManagerApp location];
CLLocationCoordinate2D coordinate = [location1 coordinate];
self.latValue= [NSString stringWithFormat:#"%f", coordinate.latitude];
self.longValue = [NSString stringWithFormat:#"%f", coordinate.longitude];
NSLog(#"Latitude = %#", self.latValue);
NSLog(#"Longitude = %#", self.longValue);
And run your project in device. If you run project in simulator then not get lat/ long.
get the current location on simulator (select any one location).
There was a mistake in code, The function which actually checking the authorization never called. I moved my all the code to viewDidLoad as below and it worked. Thank you for looking into this.
- (void)viewDidLoad {
self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.delegate = self;
self.locationManager.distanceFilter = kCLDistanceFilterNone;
self.locationManager.desiredAccuracy = kCLLocationAccuracyBest;
#ifdef __IPHONE_8_0
if(IS_OS_8_OR_LATER)
{
[self.locationManager requestAlwaysAuthorization];
}
#endif
[self.locationManager startUpdatingLocation];
[self.locationManager startUpdatingLocation];
NSLog(#"%#", [self deviceLocation]);
[super viewDidLoad];
}
I want to get the coordinates of the user, once user starts the app it should initialise GPS coordinates. I have followed this tutorial:
http://www.iosdevnotes.com/2011/10/ios-corelocation-tutorial/
I have created a class named CurrentLocationWithGPS
This is the header:
#import <Foundation/Foundation.h>
#import <CoreLocation/CoreLocation.h>
#interface CurrentLocationWithGPS : NSObject<CLLocationManagerDelegate>
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation;
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error;
- (void) getLocations;
- (Float32) latitude;
#property (strong, nonatomic) CLLocationManager *locationManager;
#property (strong, nonatomic) CLLocation *currentLocation;
#end
This is the implementation:
#import "CurrentLocationWithGPS.h"
#implementation CurrentLocationWithGPS
#synthesize locationManager, currentLocation;
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {
self.currentLocation = newLocation;
if(newLocation.horizontalAccuracy <= 100.0f) { [locationManager stopUpdatingLocation]; }
}
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error {
if(error.code == kCLErrorDenied) {
[locationManager stopUpdatingLocation];
} else if(error.code == kCLErrorLocationUnknown) {
// retry
} else {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Error retrieving location"
message:[error description]
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
}
}
- (void) getLocations {
NSLog(#"GPS Location is initialising...");
locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
[locationManager startUpdatingLocation];
NSLog(#"GPS Location is initialised...");
}
- (Float32) latitude {
return currentLocation.coordinate.latitude;
}
- (Float32) longitude {
return currentLocation.coordinate.longitude;
}
#end
I call the getLocations function in a separate thread so that it wouldn't block anything else. Here is how I call it from another class:
- (void)viewDidLoad
{
[super viewDidLoad];
NSThread *myThread =[[NSThread alloc]initWithTarget:self selector:#selector(locationSet) object:nil];
[myThread start];
}
- (void) locationSet {
CurrentLocationWithGPS *locationFind = [[CurrentLocationWithGPS alloc] init];
locationFind.getLocations;
NSLog(#"latitude is %f", locationFind.latitude);
}
Now the problem is both latitude and longitdute functions are returning 0.000, what am I missing here? I am developing for iOS6.1.
First conforms CLLocationManagerDelegate in .h file like this
#interface CurrentLocationWithGPS : NSObject<CLLocationManagerDelegate>
You need to set CLLocation's Delegate in this method.
- (void) getLocations
{
NSLog(#"GPS Location is initialising...");
locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
locationManager.distanceFilter = kCLDistanceFilterNone;
[locationManager startUpdatingLocation];
NSLog(#"GPS Location is initialised...");
}
Do you getting the Current Location on the output . Or R you just trying to retrieve the Co-ordinates ?..
It's still confusing , anyhow
Put this part of code on Your getLocations method
I Hope that You are not at all checking with Location Services . You
Should enable the LocationServices for your app else You always get
null values Check with the Condition:
if ([CLLocationManager locationServicesEnabled])
{
}
For Example :
CLLocationManager *locationManager = [[CLLocationManager alloc] init];
if ([CLLocationManager locationServicesEnabled])
{
locationManager.delegate = self;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
locationManager.distanceFilter = kCLDistanceFilterNone;
[locationManager startUpdatingLocation];
}
location = [locationManager location];
CLLocationCoordinate2D coordinate = [location coordinate];;
NSString *str=[[NSString alloc] initWithFormat:#" latitude:%f longitude:%f",coordinate.latitude,coordinate.longitude];
And Let me know , .????
