I need to display 10 – 1000 images on a UIScrollView. Paging is enabled. So every page of the scrollview is an image, it is an uiimage. I can load 10 images to 10 uiimages which stays in the memory, but with 1000 images I have problems on the iPhone or on the iPad. I am trying to unload and then load the images when I am doing scrolling. I every time displays 3 images. The current page image, and the -1 and +1 pages. When I am scrolling I unload the image and then load the next. With this method I have two problems. The scrolling is laggy and if I scroll very fast the images don’t appear. Maybe is there any good solution for these problems? Can you suggest me one?

    Perhaps the TTPhotoViewController from the three20 project would be useful.
