If I delete a game on my iphone, can I use icloud to get the data back?

I got GTA Vice City 100% Completion on my iphone and I saw gta San Andreas but I need to delete gta vice city to get it. I used cloud saving so I if I delete the game and download it again, will my cloud save of gta vice city still be there? I really want to play gta sa but If I delete gta VC, will I still have my cloud save back?

Yes. To re-download simply go to the app store and search for the game again or go to the Updates option on the bottom-left corner of the screen and go to the Purchased section usually on the top and look for it in the list.

Simple answer. Yes, because it is in the memory of your Apple product.
