Consider the above's IB objects listing. Siblings further down the list should be on top of the siblings listed further up when rendered on the screen.

Under Xcode 4.5.2, everything is ok if iphone simulator 5.1 is used. But for simulator 6.0 the map just covers everything. The same if using actual devices (phones) for testing.

Hope that somebody knowledgeable could help.

Please also add comments if you do not find such a problem on simulator 6.0. Because chances are the problem is related to how my project is setup.

Update :

Have setup a test project with the iOS 6 map view. There seems to be no problem with the z-order. So the problem should relate to my code.
