this is a great example of what you are looking for thumbnailpickerview
or you can use iCarousel library to create scrolling thumbnails as well. here is the link iCarousel
Question
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.
