Question

I want to get the user’s current location from my iPhone app. I want to show the user’s current location like country name, latitude, longitude information in my app. And also i want to show the location in Google map also. I have tried Google search also, but can’t get the exact answer. I have get the info that was to use CLLocationManager in my app to track the location. How do i use this? I have download one sample app from Apple Documents. Here is the link: https://developer.apple.com/library/ios/#samplecode/LocateMe/Introduction/Intro.html

1) I have get the info that was to use CLLocationManager in my app to track the location. How do i use this?

in .h file

#include <CoreLocation/CLLocationManagerDelegate.h>
#include <CoreLocation/CLError.h>
#include <CoreLocation/CLLocation.h>
#include <CoreLocation/CLLocationManager.h>

CLLocationManager   * myLocationManager;

CLLocation          * myLocation;

in .m file :-

    -(void)findMyCurrentLocation
    {           

    self.myLocationManager = [[[CLLocationManager alloc] init] autorelease];
    [[self myLocationManager] setDelegate:self ];
    [myLocationManager startUpdatingLocation];

    double latitude=34.052234;
    double longitude=-118.243685;

    CLLocation *defaultLocation =[[CLLocation alloc] initWithLatitude:latitude longitude:longitude];
    [self setMyLocation:defaultLocation];
    [defaultLocation release];

    if( [CLLocationManager locationServicesEnabled] )
    {   
        NSLog(@"Location Services Enabled....");
        locationServicesEnabled=TRUE;
        UIAlertView *alert = [ [UIAlertView alloc] initWithTitle:@"Information" 
                                                         message:@"Fetching your current location." 
                                                        delegate:self 
                                               cancelButtonTitle:@"OK" 
                                               otherButtonTitles:nil ];
        [alert release];
    }
    else
    {   
        NSLog( @"Location Services Are Not Enabled...." );
        locationServicesEnabled=FALSE;
        UIAlertView *alert = [ [UIAlertView alloc] initWithTitle:@"Information" 
                                                         message:@"Location service is not enable. Please enable it from settings." 
                                                        delegate:self 
                                               cancelButtonTitle:@"OK" 
                                               otherButtonTitles:nil ];
        [alert release];
     }

        }

    - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation: (CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
    {
      [self setMyLocation:newLocation];

    NSString *tempLat = [ NSString stringWithFormat:@"%3.6f" , (newLocation.coordinate.latitude) ];
    NSString *tempLong= [ NSString stringWithFormat:@"%3.6f" , (newLocation.coordinate.longitude)];

    appDelegate.curlat = tempLat;
    appDelegate.curlong = tempLong;
   }

     - (void)locationManager: (CLLocationManager *)manager didFailWithError: (NSError *)error
     {
    printf("\nerror");
    UIAlertView *alert = [ [UIAlertView alloc] initWithTitle:@"Error" 
                                                     message:@"Error while getting your current location." 
                                                    delegate:self 
                                           cancelButtonTitle:@"OK" 
                                           otherButtonTitles:nil ];

    [alert release];
     }

2). I want to show the user’s current location like country name information in my app.

For this you can to use Google’s Reverse Geo coding OR MKReverseGeocoder
