Creating a grid view to view contents of camera roll in a view

Question

I am trying to create a custom way for the user to select items from their camera roll, a bit like instagram does in their app. When the user presses the select from camera roll button, I would like the grid with all of the images to slide up over the camera.

I need the grid to be in a UIView so that I can present it in the camera's custom overlay. How would I make it so that the grid is in a view, not a view controller.

Here is the kind of thing I am looking to create (from instagrams camera):
