您将如何在iPhone应用程序中实现可滚动网格？

I have about 50 images of 50 x 50 pixel size each. I want the user to pick one of them. So first I thought about an UITableView, but that's just not the right thing. It wastes a lot of screen space. Rather than putting all images one below the other, it would be better to show a grid of lets say 6 columns and n rows.I have about 50 images of 50 x 50 pixel size ea
