I encountered a similair problem at a current app project. I wanted to be able to show detail-content on a map, corresponding with the current selected pin/marker on the map.

My result: http://i.imgur.com/P7HTtJI.gif

I tried to implement it in a way that the content snaps back to position if the use doesn't touch the screen for 1500ms. Works pretty sweet. You can use the content area for a list, as I did (I also implemented a segment view -> the tabs)

I don't know any other apps that do this :)

iOS 9 Search/Maps has split screen map and table views. It looks pretty good and works great.

Thanks everyone for inputs. Does help :)

Find my Friends by Apple has a split view with the map on top and the list view on the bottom.

It works a bit differently when scrolling compared to the other examples. Panning the map makes it fullscreen and puts a back button in the navigation bar (taking you back to the split view). Scrolling in the list keeps you in the split view.

Do you want something like urbanspoon where there is a small map and a scrollable list below and both are fixed. Or more like google maps where as you scroll the list it starts covering up the map?

The old Foursquare had a split view, but was removed after the rebrand work.
