Hello, I have a pretty simple app that displays the users current location on a map, but unfortunately i'm having some issues and was hoping someone here could help, since my search results were fruitless.
I call [myMapView setShowsUserLocation:YES]; in the application:didFinishLaunchingWithOptions: methods in myAppDelegate.m file, which successfully puts the little blue dot of my map of my location (well, Apple HQ, since I'm using the simulator.)
I have also implemented the mapView:didAddAnnotationViews: method, but unfortunately it never runs, which it should after it adds the blue dot annotation to my map. Any ideas? I will post the relevant code below. Thanks!
