I have been using GMSMap in my app. I want in my GMSMap user current location lat long. I am used lots of method but don't get current location. Please help and guid how to get my current location. I have read many tutorial and follow but don't get.
I have one question, I am using methods and any other work will be in my project? I am so tired please help.
Firstly I have write show bellow methods in my project then create IPA and install my device. But don't get current location latitude longitude.
Please help. Thankyou
First
-(void)CurrentLocationIdentifier
{
//---- For getting current gps location
locationManager = [CLLocationManager new];
locationManager.delegate = self;
locationManager.distanceFilter = kCLDistanceFilterNone;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
[locationManager startUpdatingLocation];
//------
}
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
currentLocation = [locations objectAtIndex:0];
[locationManager stopUpdatingLocation];
CLGeocoder *geocoder = [[CLGeocoder alloc] init] ;
[geocoder reverseGeocodeLocation:currentLocation completionHandler:^(NSArray *placemarks, NSError *error)
{
if (!(error))
{
CLPlacemark *placemark = [placemarks objectAtIndex:0];
NSLog(@"\nCurrent Location Detected\n");
NSLog(@"placemark %@",placemark);
NSString *locatedAt = [[placemark.addressDictionary valueForKey:@"FormattedAddressLines"] componentsJoinedByString:@", "];
NSString *Address = [[NSString alloc]initWithString:locatedAt];
_adrs_lbl.text = Address;
NSString *Area = [[NSString alloc]initWithString:placemark.locality];
NSString *Country = [[NSString alloc]initWithString:placemark.country];
_lat_lbl.text = Country;
NSString *CountryArea = [NSString stringWithFormat:@"%@, %@", Area,Country];
NSLog(@"%@",CountryArea);
_long_lbl.text = CountryArea;
}
else
{
NSLog(@"Geocode failed with error %@", error);
NSLog(@"\nCurrent Location Not Detected\n");
//return;
//CountryArea = NULL;
}
}];
}
Second
- (void)viewDidLoad
{
[super viewDidLoad];
if ([CLLocationManager locationServicesEnabled]) {
self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.delegate = self;
[self.locationManager startUpdatingLocation];
} else {
NSLog(@"Location services are not enabled");
}
}
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
CLLocation *location = [locations lastObject];
self.latitudeValue.text = [NSString stringWithFormat:@"%f", location.coordinate.latitude];
self.longtitudeValue.text = [NSString stringWithFormat:@"%f", location.coordinate.longitude];
}
UPDATED QUESTION
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray<CLLocation *> *)locations{
currentLocation = [locations lastObject];
if (currentLocation != nil){
NSLog(@"The latitude value is - %@",[NSString stringWithFormat:@"%.8f", currentLocation.coordinate.latitude]);
NSLog(@"The logitude value is - %@",[NSString stringWithFormat:@"%.8f", currentLocation.coordinate.longitude]);
}
