#import <CoreLocation/CoreLocation.h>
#import <MapKit/MapKit.h>
@interface Map_view : UIViewController<MKMapViewDelegate,CLLocationManagerDelegate>{
    CLLocationManager *locationmgr;
    CLGeocoder *geocode;
    CLPlacemark *placemark;

}
@property(nonatomic,retain)IBOutlet MKMapView *map11;

.m file:

@synthesize map11;

I don't no where to put my latitude and longitude and how to use please help me.

If you want to show your location with your lat & long with Annotation With Name.

Use this code.

- (void)viewDidLoad {
    [super viewDidLoad];

    mapVW.showsUserLocation = YES;
    CLLocation *loc = [[CLLocation alloc]initWithLatitude:12.940358 longitude:80.208647];

    [mapVW setCenterCoordinate:loc.coordinate animated:YES];

    CLGeocoder *ceo = [[CLGeocoder alloc]init];
    [ceo reverseGeocodeLocation:loc
              completionHandler:^(NSArray *placemarks, NSError *error) {
                  CLPlacemark *placemark = [placemarks objectAtIndex:0];

                  //String to hold address
                 NSString *locatedAt = [[placemark.addressDictionary valueForKey:@"FormattedAddressLines"] componentsJoinedByString:@", "];
                 NSString *cityName = placemark.locality;

                  MKPointAnnotation *annotationPoint = [[MKPointAnnotation alloc] init];
                  annotationPoint.coordinate = CLLocationCoordinate2DMake(12.940358, 80.208647);
                  annotationPoint.title = locatedAt;

                  MKCoordinateRegion region;

                  MKCoordinateSpan span1;
                  span1.latitudeDelta =  0.08;
                  span1.longitudeDelta = 0.08;
                  region.span = span1;
                  region.center = annotationPoint.coordinate;
                  [mapVW setRegion:region animated:TRUE];
                  [mapVW regionThatFits:region];

                  [mapVW addAnnotation:annotationPoint];
                  [mapVW selectAnnotation:annotationPoint animated:NO];
              }
     ];

}
