UICollectionView Custom Cell to fill width In Swift

Question

I\'ve been trying to figure-out how can i make the cell fill the width, as you can see in the picture the width between the cells is too big. i am using custom cell with only on

Answer 1

For my case, I wanted to show two columns and 3 rows in the UICollectionView

I added UICollectionViewDelegateFlowLayout delegate to my class

then I override sizeForItemAt indexPath

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
    let cellHeight = (collectionView.bounds.size.height - 30) / 3 // 3 count of rows to show
    let cellWidth = (collectionView.bounds.size.width - 20) / 2 // 2 count of colomn to show
    return CGSize(width: CGFloat(cellWidth), height: CGFloat(cellHeight))
}

The 30 is the Line spacing, the 20 is the insent between cells
