hope this fix your issue Perhaps a table view with custom cell content would work better for you, since it has a lot of logic built in for only loading cells that are visible as opposed to everything at once. There are lots of tutorials for how to manage table views in various ways.

Strategy to lazy load images for buttons within UIScrollView?

wish of those help Without actually trying it out, here's my idea:
You can use the UIScrollViewDelegate method scrollViewDidScroll: to find out when your scroll view finished scrolling and then use [UIScrollView contentOffset] to determine which part of the scroll view is visible and (CGRect)convertRect:(CGRect)rect fromView:(UIView *)view to determine the button's position within the visible part of the scroll view. Have a method that checks if the button has had its image loaded yet and if not, load it and refresh the view if necessary.

I hope this helps . Checkout Apple's sample code for PageControl. It shows you how to use a UIScrollView and UIPageControl to cycle through view controllers (just like the photo app). Each page is loaded only as needed.
Basically to achieve lazy loading you start off with an array of empty view controllers. Then as you scroll you load only the current page's view controller as well as the previous and next ones so that scrolling appears smooth. Just look over the sample project, it's fairly short and simple to follow. It should at least get you started. The UIScrollView will tell the appropriate controller when to load itself. It is then the controller's responsibility to load its content (in your case an image).

Hope that helps You need to make sure that anything which takes time happens asynchronously. The techniques for this will vary based on what kind of content you're loading or what sort of drawing you're doing that causes the delays. Try to load images in the background, do custom drawing in the background, use operations or gcd to break up large tasks into smaller chunks that can happen concurrently, etc.
