Gulam Moledina is the developer of GMGridView, a very nice UI control for managing a grid of views. You can move grids, use pinch, rotate and pan gestures, and create both vertical and horizontal layouts.
The screenshot below shows a two column vertical grid. Item 96 is shown in a different color as this is a cell that can be moved, which was initiated by a long tap on the same.
The screenshot that follows shows a variation in which there are two grids, one that is horizontal (green) and one that is vertical (purple).
You can download GMGridView from github.
