Creating an object instance that conforms to a protocol

I've created a protocol (LEService) that I will conform to in multiple UIViewControllers. I won't know until runtime which UIViewController service has been chosen.

Is there anyway to create an instance of an object that conforms to a protocol without saying what the object is until runtime?

Sure, you can do it like this:

id <LEService> objectName = [self returnObjectConformingToLEServiceProtocol];

id is Objective C's generic type.
