How to give a location coordinate to plot a point in a map in ios using storyboard?

Question

I am creating a map view in a view controller, using storyboard.

When I use the following code.

-(void) mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation
{
    CLLocationDistance distance = 1000;   
    MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(userLocation.coordinate,
                               distance, 
                               distance);
    MKCoordinateRegion adjusted_region = [self.mapView regionThatFits:region];
    [self.mapView setRegion:adjusted_region animated:YES];
}

A point is plotted in San Francisco, CA, United States. The userLocation coordinates are the predefined value in MapKit.h framework. Now I create a

-(void) mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation
{
    CLLocationDistance distance = 1000;
    CLLocationCoordinate2D myCoordinate;
    myCoordinate.latitude = 13.04016;
    myCoordinate.longitude = 80.243044;
    MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(myCoordinate, 
                                                                   distance, 
                                                                   distance);
    MKCoordinateRegion adjusted_region = [self.mapView regionThatFits:region];
    [self.mapView setRegion:adjusted_region animated:YES];
}

Here, the region is displayed having the coordinate in the center. But, no point is plotted at the coordinate position.

How to plot a point or annotation in that coordinate location?

Try this code inside of didUpdateUserLocation method

    MKPointAnnotation*    annotation = [[MKPointAnnotation alloc] init];
    CLLocationCoordinate2D myCoordinate;
    myCoordinate.latitude=13.04016;
    myCoordinate.longitude=80.243044;
    annotation.coordinate = myCoordinate;
    [self.mapView addAnnotation:annotation];

Ya,thank u, this works perfect, can we use any icons(own Pictures) other than annotation. – chandru Nov 20 '13 at 06:22
You can use -(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id )annotation {} this method to customize annotation. – Bhumeshwer katre Nov 20 '13 at 06:24
You can get idea through this link http://blog.asolutions.com/2010/09/building-custom-map-annotation-callouts-part-1/ – Bhumeshwer katre Nov 20 '13 at 06:35

Add this code in didUpdateUserLocation

MKAnnotation *annotation = [[MKAnnotation alloc] initWithCoordinate:CLLocationCoordinate2DMake(latitude, longitude)];
[myMap addAnnotation:annotation];

Three errors are displayed, use of undeclared identifier "Annotation". – chandru Nov 20 '13 at 06:19

Try This.. //MAP VIEW Point

MKCoordinateRegion myRegion;

//Center
CLLocationCoordinate2D center;
center.latitude=latitude;
center.longitude=longitude;

//Span
MKCoordinateSpan span;
span.latitudeDelta=THE_SPAN;
span.longitudeDelta=THE_SPAN;

myRegion.center=center;
myRegion.span=span;

//Set our mapView
[MapViewC setRegion:myRegion animated:YES];

//Annotation

//1.create coordinate for use with the annotation
CLLocationCoordinate2D wimbLocation;
wimbLocation.latitude=latitude;
wimbLocation.longitude=longitude;

Annotation * myAnnotation= [Annotation alloc];

myAnnotation.coordinate=wimbLocation;

THE_SPAN 0.01f In the place of latitude and longitude give your value... – Sukesh Nov 20 '13 at 06:21
Wat is that above comment – chandru Nov 20 '13 at 06:29
In the above coding in the place of THE_SPAN give value 0.01f,and in the place of latitude and longitude give your latitude and longitude values.. – Sukesh Nov 20 '13 at 06:32
k, wat is that MapViewC – chandru Nov 20 '13 at 06:36
you would have declared the map view in .h file. Use the same name here and try. – Sukesh Nov 20 '13 at 06:41
Ya, thank u, can we plot our own pictures instead of annotation – chandru Nov 20 '13 at 06:43
