How to get the coordinate values of current location in maps in iphone?

Question

I am new to iphone development.I am creating a map application.I am getting the current location and able to print the co-ordinates with %g format.What is that format.Can i save the coordinates in a integer local variable to load the current location in map. please help me out.Is there any other alternate to load the current location in device by getting its value.

NSLog(@"%g", newLocation.coordinate.latitude);
NSLog(@"%g", newLocation.coordinate.longitude);

This prints the value .but how can i save this value in integer?Please help me out.Thanks.

EDIT

double val1=newLocation.coordinate.latitude;
double val2=newLocation.coordinate.longitude;
MKCoordinateRegion region1;
region1.center.latitude=val1;
region1.center.longitude=val2;
region1.span.latitudeDelta=0.0;
region1.span.longitudeDelta=0.0;

mapView.mapType=MKMapTypeHybrid;
mapView.region=region1;

The console window

2010-02-18 23:29:29.403 eDev[5817:207] val 2 is -122.031

Answer 1

The span lat/long delta cannot be zero. Try something like 0.01.
