Detecting iBeacons with different UUIDs

Question

I'm trying to use UUIDs as identifiers for specific beacons (using phones in this case). I understand that major and minor are used to do this, but I'd rather use the UUID, or the identifier string.

With that being said, is there anyway to scan for beacons regardless of UUIDs with the CLBeacon API?

On Android you can scan for all UUIDs. On iOS you cannot. See:

On iOS, CoreLocation limits you to monitoring for at most 20 different UUIDs. Ranging does not have a limit of 20, but you still must know the UUIDs ahead of time.
