The area of the map that is visible to a user at runtime is specified by the map's initial viewpoint (initial). The user can explore different areas of the map by panning, zooming, or rotating, using a range of gestures that are built-in to the map view.
User gestures
Below are the map view's gestures that are provided for every iOS device. Each of these gestures will change the map view's viewpoint, and their use will trigger the map view's viewpoint (see
GeoView.viewpointChangedHandler
). This handler will, in turn, trigger a block in which you can include additional code.
