get current address of user in xcode? - ios

Question

I need to get the exact current address (country,state,city) of user. So I have gone to find latitude and longitude and then find out from it by using reverse geocoding.But unable to get latitude and longitude itself.I m using xcode 4.1 and testing in iphone simulator.
This is the code I m working on:
- (void)viewDidLoad
{
[super viewDidLoad];
locationManager = [[CLLocationManager alloc] init];
locationManager.distanceFilter = kCLDistanceFilterNone;
locationManager.desiredAccuracy = kCLLocationAccuracyHundredMeters;
[locationManager startUpdatingLocation];
NSLog(#"%#", [self deviceLocation]);
}
- (void)locationManager:(CLLocationManager *)manager
didUpdateToLocation:(CLLocation *)newLocation
fromLocation:(CLLocation *)oldLocation
{
int degrees = newLocation.coordinate.latitude;
double decimal = fabs(newLocation.coordinate.latitude - degrees);
int minutes = decimal * 60;
double seconds = decimal * 3600 - minutes * 60;
NSString *lat = [NSString stringWithFormat:#"%d° %d' %1.4f\"",
degrees, minutes, seconds];
latLabel.text = lat;
degrees = newLocation.coordinate.longitude;
decimal = fabs(newLocation.coordinate.longitude - degrees);
minutes = decimal * 60;
seconds = decimal * 3600 - minutes * 60;
NSString *longt = [NSString stringWithFormat:#"%d° %d' %1.4f\"",
degrees, minutes, seconds];
longLabel.text = longt;
}
How can I find the latitude and longitude and thereby find the address of the user?
EDIT:
Updated my version to Xcode 4.5. But still couldnot see the location ....?Y is it so?

Answer 1

please download this file
In the zip file I attached, there are 4 files:
LocationGetter.h and .m
PhysicalLocation.h and .m
you need to just import
#import "PhysicalLocation.h"
PhysicalLocation *physicalLocation = [[PhysicalLocation alloc] init];
[physicalLocation getPhysicalLocation];
in getPhysicalLocation at PhysicalLocation.m class
#pragma mark MKReverseGeocoder Delegate Methods
- (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFindPlacemark:(MKPlacemark *)placemark
{
NSLog(#"%#",placemark);
objcntrAppDelegate = (yourappDeleger *)[[UIApplication sharedApplication]delegate];
objcntrAppDelegate.strCountry=placemark.country;
objcntrAppDelegate.strSuburb=placemark.subAdministrativeArea;
[[NSNotificationCenter defaultCenter] postNotificationName:#"ReceivedAddress" object:nil userInfo:nil];
[geocoder autorelease];
}
You get all of you neat lat, lng, current city, country, all that you need. Hope it helps you.
NOTE:- simulator gives incorrect result, you must test on device.

Answer 2

Change :
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
Now latitude and longitude should be obtained as float not int.
CLLocation *location = [locationManager location];
// Configure the new event with information from the location
CLLocationCoordinate2D coordinate = [location coordinate];
float longitude=coordinate.longitude;
float latitude=coordinate.latitude;
Find address of the user by latitude and longitude using CLGeocoder.
