Location Issue in iPhone Device - ios

Question

I want to detecting user's current location in my app.I am using objective c.It's working fine in simulator but while testing on device below error comes.
didFailWithError: Error Domain=kCLErrorDomain Code=0 "The operation couldn’t be completed. (kCLErrorDomain error 0.)"
Please Help me to solve this issue.I am using Lat long value for find out place mark in my application.
if(version<8.0)
{
locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
[locationManager startUpdatingLocation];
}
else
{
locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
// Check for iOS 8. Without this guard the code will crash with "unknown selector" on iOS 7.
if ([locationManager respondsToSelector:#selector(requestWhenInUseAuthorization)]) {
[locationManager requestWhenInUseAuthorization];
}
[locationManager startUpdatingLocation];
}
Here are delegate method
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error{
NSLog(#"didFailWithError: %#", error);
UIAlertView *errorAlert = [[UIAlertView alloc]
initWithTitle:#"Error" message:#"Failed to Get Your Location" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[errorAlert show];}
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation{
NSLog(#"didUpdateToLocation: %#", newLocation);
CLLocation *currentLocation = newLocation;
if (currentLocation != nil) {
NSString *longitude = [NSString stringWithFormat:#"%.8f", currentLocation.coordinate.longitude];
NSString *latitude = [NSString stringWithFormat:#"%.8f", currentLocation.coordinate.latitude];
CLGeocoder * geoCoder = [[CLGeocoder alloc] init];
[geoCoder reverseGeocodeLocation: locationManager.location completionHandler:
^(NSArray *placemarks, NSError *error) {
CLPlacemark *placemark = [placemarks objectAtIndex:0];
NSString *placemark_str = [placemark locality];
subAdminArea.text=placemark.subAdministrativeArea;
NSString *are_str = [placemark subLocality];
subAdminArea.text=placemark.subAdministrativeArea;
NSString *location_str=[NSString stringWithFormat:#"%#,%#",are_str,placemark_str];
[[NSUserDefaults standardUserDefaults]setValue:location_str forKey:#"Location"];
NSLog(#"place mark str: %#",placemark_str);
}];
}}
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations{
NSLog(#"%#", [locations lastObject]);
CLGeocoder * geoCoder = [[CLGeocoder alloc] init];
[geoCoder reverseGeocodeLocation: [locations lastObject] completionHandler:
^(NSArray *placemarks, NSError *error) {
CLPlacemark *placemark = [placemarks objectAtIndex:0];
NSString *placemark_str = [placemark locality];
NSString *are_str = [placemark subLocality];
NSString *location_str=[NSString stringWithFormat:#"%#,%#",are_str,placemark_str];
[[NSUserDefaults standardUserDefaults]setValue:location_str forKey:#"Location"];
}];}
- (void)requestAlwaysAuthorization{
CLAuthorizationStatus status = [CLLocationManager authorizationStatus];
// If the status is denied or only granted for when in use, display an alert
if (status == kCLAuthorizationStatusAuthorizedWhenInUse || status == kCLAuthorizationStatusDenied) {
NSString *title;
title = (status == kCLAuthorizationStatusDenied) ? #"Location services are off" : #"Background location is not enabled";
NSString *message = #"To use background location you must turn on 'Always' in the Location Services Settings";
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:title
message:message
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"Settings", nil];
[alertView show];
}
// The user has not enabled any location services. Request background authorization.
else if (status == kCLAuthorizationStatusNotDetermined) {
[locationManager requestAlwaysAuthorization];
}}
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
if (buttonIndex == 1) {
// Send the user to the Settings for this app
NSURL *settingsURL = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
[[UIApplication sharedApplication] openURL:settingsURL];
}}
I have also update my plist file with NSLocationAlwaysUsageDescription->String & NSLocationWhenInUseUsageDescription -> String.
Thank You.

1) check that you actually have a valid WiFi and 3G connection
if you do then
2) go to settings and reset your location services
3) then reset your network settings
