Objective-C add MKOverlay to map view animated fade in

I've been trying to add an MKOverlay to a map with animation. I'm trying to make it fade in when it's added and fade out when it's removed. Could this be done by created a custom overlay class or overlay view class?

On iOS 7 you could achieve this even with the new MKOverlayRenderer. It has an alpha property which you could animate by setting up a timer to repeatedly change its value and call setNeedsDisplayInMapRect:zoomScale:.

This is trickier in iOS 7 and above since the overlays aren't represented with views anymore, but rather drawn with renderers (either using the stock ones or rendering yourself in a provided CGContext in the delegate).

Whatever you do here will be rendered on a tiled basis, which could lead to differences in appearance across you map view.
