  1. POTelling the difference between UserLocation Pin and user added pins
    text
    copied!<p>I am trying to solve a problem that I'm not sure how to solve. In my app, when the mapkit launches, I drop a pin at the user's current location. The mapkit delegates to viewForAnnotation which sets the pin's color which works fine. </p> <p>The issue I'm running into is I cannot tell the annotations apart so I can apply a different color to "user added locations" vs. my "current location" pin. I would like to add a button so they can delete any pins they add but not be able to delete their "current location" pin. I can't seem to figure out how to extract any identifiable pieces of information like title or subtitle of the pin. </p> <p>Thanks in advance for your help.</p> <p>Here's my code...</p> <pre><code> - (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id &lt;MKAnnotation&gt;)annotation { NSLog(@"OAAssignmentGPSViewController.m : mapView viewForAnnotation"); if([annotation isKindOfClass: [MKUserLocation class]]) return nil; NSLog(@" mapView.userLocation.title = %@", self.mapView.userLocation.title); static NSString* annotationIdentifier = @"currentlocation"; MKPinAnnotationView *myPinView = (MKPinAnnotationView *)[self.mapView dequeueReusableAnnotationViewWithIdentifier:annotationIdentifier]; if (!myPinView) { myPinView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:nil] ; myPinView.pinColor = MKPinAnnotationColorRed; myPinView.canShowCallout = YES; myPinView.animatesDrop = YES; NSLog(@"mapView.description %@", self.mapView.userLocation.title); if( annotation != self.mapView.userLocation)&lt;&lt;&lt;&lt;&lt;----how do I check for UserLocation { myPinView.pinColor = MKPinAnnotationColorGreen; myPinView.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure]; } } return myPinView; } </code></pre>
