I can't seem to find any information on how Core Location handles overlapping geofences. In my particular case I was wondering if a smaller geofence would be registered over a bigger, overlapping region. Does someone know this?

Core Location will register when you enter a geofenced area whether you are currently in another area or not. Consider this example for a clear understanding.
If I set a geofence around the entire United States and a smaller geofence around the state of Florida.
When I Enter the United States it will register that I entered the United States geofence. When I enter Florida, it will register that I entered the Florida geofence, but I don't leave the United States geofence; I am now in both geofences. If I go to Georgia, it will register that I exited the Florida geofence, but I am still in the United States Geofence. If I exit Florida through the ocean and leave Florida and the United States, it will register that I have exited both the United States and Florida geofences.
So, no. Smaller geofences are not registered over a bigger overlapping region. They are both registered as if they know nothing about the other geofences that are being monitored.

Thank you for the clarification. Is there any property for currently active regions, or do I have to handle an array with i/o from -didEnter: and -didExit myself? – Oscar Apeland Feb 12 '16 at 20:57

I've always handled with an array from didEnter and didExit – MSU_Bulldog Feb 12 '16 at 20:58
