MapView, how can I change the distance?

Question

In mapview, how can I change it from A to B as in the picture?

And here is the code:

#define BE_Latitude 25.9444055
#define BE_longtitude -80.1229769

#define BEMSpan 0.100f;

Picture

EDITED

Code

#import "BEViewController.h"
#import "BENSObject.h"

@interface BEViewController ()

@end


#define BE_Latitude 25.9444055
#define BE_longtitude -80.1229769

#define BEMSpan 0.100f;

@implementation BEViewController
@synthesize BEMapView;

- (void)viewDidLoad {
    [super viewDidLoad];

    MKCoordinateRegion BERegion;

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

    //Span
    MKCoordinateSpan span;
    span.latitudeDelta = BE_Latitude;
    span.longitudeDelta = BE_longtitude;

    BERegion.center = center;
    BERegion.span = span;

    //Set our map
    [BEMapView setRegion:BERegion animated:YES];


    CLLocationCoordinate2D BELocation;
    BELocation.latitude = BE_Latitude;
    BELocation.longitude = BE_longtitude;

    BENSObject * BEAnnitation = [[BENSObject alloc] init];
    BEAnnitation.coordinate = BELocation;
    BEAnnitation.title = @“C”;
    BEAnnitation.subtitle = @“D”;


    {[self.BEMapView addAnnotation:BEAnnitation];

    }
}

    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

Are you sure thats all the code? Is this android or iOS, your tags are conflicting. Could you post the code where these variables are actually used — Flexicoder, May 16 '16 at 13:58
You want the map zoomed in? Nobody is going to be able to help you unless you post some code — Flexicoder, May 16 '16 at 14:08

To change the zoom level you want to adjust your MKCoordinateSpan. Apple Docs on MapKit Data Types will help here.

You are currently using your location coordinates for the latitudeDelta and longitudeDelta.
