UICollectionView Auto Height

Question

i have a view with different subviews including a uiviewcollection, the thing is, i don't know how dynamically modify the uicollectionview height, the sizes of the cell is a fixed size, i'm just looking a way to figure out how make the uicollectionview height dynamic to show all the items, the number os items are not fixed.

Any help?

Thank you

You need to set height constraint of UICollectionView. Then Calculate your CollectionView height as per

(topSpacing + bottomSpacing + cellHeight) * number of cells (items)

then set heightConstraint again for your collectionview.
