MKMapView zoom to users location on viewDidLoad?

Question

I\'m trying to zoom a map into the user\'s current location once the view loads, but I\'m getting the error \"** * Terminating app due to uncaught exception \'NSInvalidA

The problem that occurs when you use the didUpdateUserLocation method, you will not be able to scroll nor zoom to another location. It will keep pointing to your location. The best way (that I've tried) is that you need to use the location manager.

In the viewDidLoad add the following :

self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.delegate = self;
self.locationManager.desiredAccuracy = kCLLocationAccuracyBest;
self.locationManager.distanceFilter = kCLLocationAccuracyKilometer;;
// showing user location with the blue dot
[self.mapView setShowsUserLocation:YES];

self.mapView.delegate = self;

// getting user coordinates
CLLocation *location = [_locationManager location];
CLLocationCoordinate2D  coordinate = [location coordinate];


// showing them in the mapView
_mapView.region = MKCoordinateRegionMakeWithDistance(coordinate, 250, 250);

[self.locationManager startUpdatingLocation];

this way you could display your location with the zoom that you want. I hope this will help.
