Question

curious if someone can help with one thing:

I’m just trying to tell Xcode that if both “addAnnotation” and “newAnnotation” pins exist on the map at the same time, then to remove the initial “newAnnotation” pin.

My non-working code is below:

if ([self.mapView addAnnotation:addAnnotation] & [self.mapView addAnnotation:newAnnotation] return)
{
    [self.mapView removeAnnotation:newAnnotation];
}

Thanks!

thank you for the feedback but i solved it with this:

NSArray *existingpoints = mapView.annotations;

if ([existingpoints count])
    [mapView removeAnnotations:existingpoints];
