ios - 如何在ios中将当前位置用户头像居中

Question

我需要在 MKView 上将当前位置的用户图片居中。但目前它不在中心，如下面的屏幕截图所示。

-

 (void)locationManager:(CLLocationManager *)manager didFailWithError:   (NSError *)error
{
    NSLog(@"didFailWithError: %@", error);
}

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
    NSLog(@"didUpdateToLocation: %@", newLocation);

    CLLocation *currentLocation = newLocation;

    if (currentLocation != nil)
    {
        NSLog(@"%@",[NSString stringWithFormat:@"%.8f", currentLocation.coordinate.longitude]);

        NSLog(@"%@",[NSString stringWithFormat:@"%.8f", currentLocation.coordinate.latitude]);

       // [mkMapView setCenterCoordinate:mkMapView.userLocation.location.coordinate animated:YES];
    }
}

-(void)mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation
{
    MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(userLocation.coordinate, 150, 150);

    [mkMapView setRegion:[mkMapView regionThatFits:region] animated:YES];
}

- (void)mapView:(MKMapView *)aMapView didUpdateUserLocation:(MKUserLocation *)aLocation {

MKCoordinateRegion region;
MKCoordinateSpan span;
span.latitudeDelta = 0.005;
span.longitudeDelta = 0.005;
CLLocationCoordinate2D location;
location.latitude = aLocation .coordinate.latitude;
location.longitude = aLocation .coordinate.longitude;
region.span = span;
region.center = location;
[aMapView setRegion:region animated:YES];
