Answer 1

- (CGSize)collectionView:(UICollectionView *)collectionView
                  layout:(UICollectionViewLayout *)collectionViewLayout
  sizeForItemAtIndexPath:(NSIndexPath *)indexPath
{
    float width = collectionView.frame.size.width / 2;
    return CGSizeMake(width, width);

}

对斯威夫特来说

func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize
{
    return CGSizeMake(collectionView.frame.size.width/2, collectionView.frame.size.width/2)
}
