This is what I want to do… Need to add Different Images to pins according to the JSON value.

is there any one has a idea how to do that? Please help and that would be very helpful.

You can use the delegate method:

-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id )annotation

and according to your JSON values you can set the image:
The below is my sample code:

UIImage * flagImage = nil;

if(Your JSON Values)
flagImage = [UIImage imageNamed:@"darkgreendot.png"];
else if(....)
flagImage = [UIImage imageNamed:@"orangedot.png"];
else
flagImage = [UIImage imageNamed:@"bluedot.png"];

CGRect resizeRect;  
        resizeRect.size = flagImage.size;   
        resizeRect.origin = (CGPoint){0.0f, 0.0f};
        UIGraphicsBeginImageContext(resizeRect.size);
        [flagImage drawInRect:resizeRect];
        UIImage *resizedImage = UIGraphicsGetImageFromCurrentImageContext();
        UIGraphicsEndImageContext();    
        annotationView.image = resizedImage;
