Question

I am currently working on an application involving mapkit. I would like to add a reset button on the view which resets the view to its default view when you open the program, or better still, the mapkit resets itself when you open and close the app.

The code i have used to set the initial region is as follows:

    MKCoordinateRegion region = { {0.0, 0.0 }, { 0.0, 0.0 } };
region.center.latitude = 54.049929;
region.center.longitude = -4.54834;
region.span.longitudeDelta = 4.5;
region.span.latitudeDelta = 4.5;
[mapView setRegion:region animated:YES];

Any help would be greatly appreciated.

Answer 1

Store the Location of your map
In .h file

CLLocationCoordinate2D location;

When setting initial Region

location.latitude = 54.049929;
location.longitude = -4.54834;

In your Reset Button

MKCoordinateRegion region = { {0.0, 0.0 }, { 0.0, 0.0 } };
region.center.latitude = location.latitude
region.center.longitude = location.longitude;
region.span.longitudeDelta = 4.5;
region.span.latitudeDelta = 4.5;
[mapView setRegion:region animated:YES];
