I have a horizontally scrolling UIScrollView and I want to display potentially thousands of UIImage's side by side. Obviously I can't do that for memory reasons so what I am thinking is set the content size to be the 2000 or whatever but only show the current window of image squares. So the user would flick the scroll bar and when it stops (it is paged so it will stop scrolling quickly), it will display the images that should be there at that point.
I haven't done that yet but sounds simple enough. I will just have 1 row of UIImage's moving around and loading different content depending upon which scrolling 'page' comes to rest.
First question - is that a good approach? Second question - how can I have an infinitely repeating tiled background image of empty squares or something to act as placeholders for content that hasn't been loaded. These will be displayed as the user is whirling the scroll bars around. Can we have a tiled BG image on UI elements?
