I have a UIScrollView that contains large images and am using paging to scroll between images. In order to save memory, I am loading only one image before and after the currently visible one and loading/releasing new images after a scroll has completed.

The problem occurs when one scrolls quickly and scrollViewDidEndDecelerating is not called.

How can I detect continuous scrolling?

I could check item location on every scrollViewDidScroll but this seems a bit heavy...
