I know its a very common issue but I am not getting the exact answer for this thing.
How to make MKMapView defaults to a zoom of a 5 mile radius of current location.
Thanks in advance.
Use the following code when ever you want to zoom to 5 miles radius:
double miles = 5.0;
double scalingFactor = ABS( (cos(2 * M_PI * newLocation.coordinate.latitude / 360.0) ));
MKCoordinateSpan span;
span.latitudeDelta = miles/69.0;
span.longitudeDelta = miles/(scalingFactor * 69.0);
MKCoordinateRegion region;
region.span = span;
region.center = newLocation.coordinate;
[mapView setRegion:region animated:YES];
