How to drag and move something and scroll at the same time in UIScrollView

Viewed 6473

I'm writing a app which has a bookshelf view like iBooks.

The problem now is: I can drag and drop a book from on place to another.But how do I make these happen at the same time when I drag book to the bottom of the scrollview:

  1. make the scrollview scroll down
  2. keep the book follow my finger
  3. place the other books at the right place with animation like moving apps in springboard

I know there's an AQGridView in Github, but it seems that the springboard demo doesn't support scroll and move at the same time.(I already set scrollEnable to YES)
