They do opposite things.
You
pushto add it to the stack of visibleUIViewControllers, andpopit to remove it.The terminology comes from the
stackdata-structure. The idea is that you “push”, or place, objects on the top of the stack, and each object can’t be removed until all the objects above it have been removed (“popped”).You can read more about stacks here.
