this is the method for call google map api for geocoding, if u pass the Zipcode/Postal code, you get the result

-(void)ViewDidLoad
{ 

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://maps.google.com/maps/api/geocode/json?sensor=false&address=%@",yourzipcodetext/PostalcodeText.text]]];

[request setHTTPMethod:@"POST"];

NSError *err;
NSURLResponse *response;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];
NSString *resSrt = [[NSString alloc]initWithData:responseData encoding:NSASCIIStringEncoding];

NSLog(@"got response==%@", resSrt);

NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableContainers error:nil];

NSString *lataddr=[[[[[dict objectForKey:@"results"] objectAtIndex:0]objectForKey:@"geometry"]objectForKey:@"location"]objectForKey:@"lat"];

NSString *longaddr=[[[[[dict objectForKey:@"results"] objectAtIndex:0]objectForKey:@"geometry"]objectForKey:@"location"]objectForKey:@"lng"];


NSLog(@"The resof latitude=%@", lataddr);

NSLog(@"The resof longitude=%@", longaddr);


}

CLGeocoder *geoCoder = [[CLGeocoder alloc] init];
    [geoCoder geocodeAddressString:@"ZIP CODE HERE" completionHandler:^(NSArray *placemarks, NSError *error) {
        CLPlacemark *placemark = [placemarks objectAtIndex:0];
        CLLocation *location = placemark.location;
        CLLocationCoordinate2D coordinate = location.coordinate;
        NSLog(@"Latitude %f", coordinate.latitude);
        NSLog(@"Longitude %f", coordinate.longitude);
    }];

It will be as simple as something like this:

CLGeocoder *geoCoder = [[CLGeocoder alloc] init];
    [geoCoder geocodeAddressString:@"ZIP CODE HERE" completionHandler:^(NSArray *placemarks, NSError *error) {
        CLPlacemark *placemark = [placemarks objectAtIndex:0];
        CLLocation *location = placemark.location;
        CLLocationCoordinate2D coordinate = location.coordinate;
        NSLog(@"Latitude %f", coordinate.latitude);
        NSLog(@"Longitude %f", coordinate.longitude);
    }];

thk for replay i got Latitude and longitude but it's showing different location plz help me thk in advanced — , Feb 06 '14 at 07:23
