Easy way to use an UIScrollView
Does someone have an "easy way" to make a view like camera roll app? I need to display miniature photos (buttons) and push new views from them. I don't know how to display miniature images in a scroll 开发者_Python百科view. The number of miniatures is large, so they don't fit the screen, and I think UIScrollView is the only solution.
Check out TTThumbsViewController
, part of Three20; this should pretty much do what you want (and it's open source if you need to change it).
A scroll view really just controls the visible region of a single content view. If you want a grid of small images, you'll need to create a view that contains a number of image views or otherwise displays the grid of images. Make this the content view of the scroll view. Also, it'd be a good idea to construct your image grid view such that it only loads and draws the images that are visible, particularly if you're going to display a large number of such images.
