Is there any class in iOS like Android 's gallery class can handle thumbnails in a bar?
a little like iPad's camera roll, there is a thumbnail bar in the bottom of the photo grid view
thank you!
If there is none,
I know maybe can use slide bar or scroll view in a UIview to implement what I want.
Can anybody can tell more about how to use scrollview or slider to implement this?
Further more, I haven't think clear is: how do the thumbnails and the big image view delegate to each other?
Thank you very much.
