Makeing an image grid in Xcode

I want to make a 8x10 grid of images. I need to turn each image on and off independently, and they need to keep a 1:1 ratio but grow and shrink so they fit on the screen. At first I tried inserting 80 different image views, that I would add to a struct so they could be represented by coordinate to be hidden and un-hidden. But this really didn't work out because it got so complicated. Now i am trying to use a collection view, that I set to a 8:10 aspect ratio and 80 containers. I added some UIImageViews to the containers and they never showed up on the simulation.

Is there a better way I could be going about this? is the collection view the right path? if so how do I format, add the images and access coordinates to turn them on and off?

Thanks in advance!

Hi Mark,

Sounds to me like a uicollectionview is exactly what you need. I would google around for some basic tutorials on them, and maybe check out this WWDC session video for some more advanced things you can do with them:
