This forces the call of the map view's display link target when the display link is created. When a map view is shown the first time this is not required. However, if the display link was torn down and then recreated due to the map view being removed / obscured in the view hierarchy the map view delegate may expect to be informed when the map view did finish loading the map when it is shown again.
This adds a call to
updateFromDisplayLink
just after a display link is created which helps trigger a full refresh of the map in the sense that all delegate methods get exercised includingmapViewDidFinishLoadingMap
