i wondered that is there system or library likes reusable system in iOS.
for example, when we create list view containing 2000 cells and user can watch only 6 cells in display,
juce only load 6 cell in gui and enqueue rest cells in reusable queue in order to economize memory efficiency. and when users scroll the list, not-dislayed cells enqueue, and dequeue cells which have to be disaplayed.
if there is no system like this, i want to make open-source library.
