Collectionview item size and amount

I'm in tad of a dilemma with an application here. Id like a CollectionView to be filled with modules and icons, positioned in the center of the display. I'm able to center the CollectionView using the AutoLayout helpers, but i cant seem to figure out how to size the items correctly.

Currently, there are 4 items in a row, where as i would like to only have two, ( 50% width ) items in a row.

I figured the itemSize attribute, and the corresponding CGsize method, but that is only static pixels ( 120, 300 ) And therefor not representative for what i would like both on large and small devices.

Are there any way to make the items lock at: 2 per. row. 50% width + gutter

Thanks in advance!

Jonas

Look at UICollectionViewDelegateFlowLayout protocol, which has datasource methods like 

sizeForItemAtIndexPath
minimumInteritemSpacingForSectionAtIndex

return custom values to layout collectionview's cells as you want.

Use collectionView.collectionViewLayout.collectionViewContentSize to get proper content size. But it will be valid only after collection view completes its layout, so you can just use collectionView's frame instead.
