ios - Animate UICollectionViewCell Reloading -

i have looked over, without luck. i'll keep short , sweet. feel should looking @ uicollectionviewlayout, not entirely sure.

i want achieve: custom animation uicollectionviewcell when data reloaded. e.g. cell contents spirals in (as example).

how can achieve this?

thanks!

you use activity indicator view. code like:

[youraiv startanimating]; [yourcollectionview reloaddata]; [youraiv stopanimating];
