MkCircle with MapKit, synchronyse with current user location - ios

Question

I am working in a project with MapKit, and I want to update the location of circle in the center of current user location. I can do that by implementing this methods. The problem is that user location when changes its coordinates animates and the method DidUpdateUserLocation doesnt get called everytime.
What I want to do is smoothly changing position with these methods faster and animating the circle like user location (blue dot) changes (dispatch wont do any of this tasks faster)
-(void)viewDidLoad
{
[super viewDidLoad];
[self UpdateCirclePosition];
}
This method get executed when user location changes.
- (void)mapView:(MKMapView *)mv didUpdateUserLocation:(MKUserLocation *)userLocation1
{
[self UpdateCirclePosition];
}
This method is to set new coordinates for the circle
-(void)UpdateCirclePosition
{
//Removing past layouts from MapView
[self.mapView removeOverlays: [self.mapView overlays]];
//Set the circle in the middle of the current user location
MKCircle *circle = [MKCircle circleWithCenterCoordinate:locationManager.location.coordinate radius:10];
[self.mapView addOverlay:circle];
}
And this is the method when overlay changes
- (MKOverlayView *)mapView:(MKMapView *)map viewForOverlay:(id <MKOverlay>)overlay
{
MKCircleView *circleView = [[MKCircleView alloc] initWithOverlay:overlay];
circleView.strokeColor = [UIColor redColor];
if (something)
{
circleView.fillColor = [[UIColor greenColor] colorWithAlphaComponent:0.2];
}
else
{
circleView.fillColor = [[UIColor redColor] colorWithAlphaComponent:0.2];
}
circleView.lineWidth = 0.5;
return circleView;
}

Answer 1

didUpdateUserLocation gets the latest position, but then you ignore it and call UpdateCirclePosition. You should pass the coordinates from userLocation1 into UpdateCirclePosition and use them to reposition your circle.
