I noticed this when running my app (which uses YangMingShan) on a friend's phone. She has a lot of photos in her camera roll (~20000), and when I press the the button to open the photo picker, the app freezes for a good 2 seconds. I reproduced it by make 20000 copies of a uiimage on my own phone.
Is there anyway to limit the number of photos that are loaded initially and then paginate if the user ever scrolls that far?
