Answer 1

这是如何做到的：

- (void)zoomToUserLocationAnimated:(BOOL)animated
{
    CLLocationCoordinate2D locationCoordinate2D = _locationManager.location;
    CLLocationDistance distance = 30000;

    [self setRegion:MKCoordinateRegionMakeWithDistance(locationCoordinate2D, distance, distance)
           animated:animated];
}
