    latitude = -latitude;
    strDirection = @"S";
 } else {

 }
 // Longitude
 CGFloat longitude = Long;

try this code below:

first add framework in your project CoreLocation.Framework after adding initialize CLLocationManager object and import CLLocationManager header file.

Yourviewcontroller.h

#import <CoreLocation/CoreLocation.h>
@interface Yourviewcontroller :UIViewController <CLLocationManagerDelegate>
{
      CLLocationManager *locationManager;
}

Yourviewcontroller.m

locationManager=[[CLLocationManager alloc] init];
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
locationManager.delegate = self;
//Start the compass updates.
[locationManager startUpdatingHeading];

add function for get current direction

-(void)locationManager:(CLLocationManager *)manager didUpdateHeading:(CLHeading *)newHeading
{
    float mHeading = newHeading.magneticHeading;
    if ((mHeading >= 339) || (mHeading <= 22)) {
        //[direction setText:@"N"]; 

    }else if ((mHeading > 23) && (mHeading <= 68)) {
        //[direction setText:@"NE"];    

    }else if ((mHeading > 69) && (mHeading <= 113)) {
        //[direction setText:@"E"]; 

    }else if ((mHeading > 114) && (mHeading <= 158)) {
        //[direction setText:@"SE"];

    }else if ((mHeading > 159) && (mHeading <= 203)) {
        //[direction setText:@"S"]; 

    }else if ((mHeading > 204) && (mHeading <= 248)) {
        //[direction setText:@"SW"];    

    }else if ((mHeading > 249) && (mHeading <= 293)) {
       // [direction setText:@"W"];

    }else if ((mHeading > 294) && (mHeading <= 338)) {
       // [direction setText:@"NW"];

     }
}

Note :compass is work only real iphone device,not work in iphone simulator..!

You could try LocateMe. It will give you the long and lat of the user's current position.
Or your could try looking at this tutorial

Hope this helps!
