With MapKit in the iPhone 3.0 SDK, you create objects that conform to the MKAnnotation protocol. Loading these onto the MKMapView is very easy. However, when a user scrolls the MKMapView, it's time to load new annotations. A likely place to request the new objects would be in mapView:regionDidChangeAnimated: which is called when the map'...
I checked the properties in documentation for MKCoordinateRegion, MKCoordinateSpan and MKMapView to see there is a way to get the TopLeft and BottomRight Lat Long from the map view and I didn't find any. I know that the span gives me the Lat long delta but is there a way to get the actual TopLeft and BottomRight lat longs from map view w...
I have a detail view that includes three UIButtons, each of which pushes a different view on to the stack. One of the buttons is connected to a MKMapView. When that button is pushed I need to send the latitude and longitude variables from the detail view to the map view. I'm trying to add the string declaration in the IBAction: - (IBAct...
Setting the region in MKMapView occasionally results in the span being doubled. This bug seems to appear early in the map initialization phase. Although it's been reported elsewhere I wasn't able to find a descent existing workaround, so I'm posting my fix here. It relies on the fact that the regionThatFits method also produces the bug. ...
Now I have the coordinate of two locations, let say locationA with latitude 40 and longitude -80, locationB with latitude 30 and longitude -70, I want to create a mapView that I can see both locations with appropriate viewing distance. I got the new coordinate by finding the midpoint (in this example, {35, -75}), but the question is, ...
I have a map that dynamically shows annotations as the user moves around. I am using the method regionDidChangeAnimated to know when the map has been moved and then I get annotations based on the new latitude and longitude. If the user zooms out then I am clustering the annotations. I want to have it so that when a user clicks on a ...
