how to set cell size of a UICollectioView programmatically in ios

I have collectionView and tableView. When I select the first cell in the tableview, 6 cells are shown in the collectionView. And when I select the second cell collectionView should show 4 cells. Now I need to increase the size of the collectionView cell when I click on the second cell of the tableview.

 - (CGSize)collectionView:(UICollectionView *)collectionView
                      layout:(UICollectionViewLayout *)collectionViewLayout
      sizeForItemAtIndexPath:(NSIndexPath *)indexPath {
        CGSize size;
        CGRect bounds = [[UIScreen mainScreen] bounds];
        double bWidth = (bounds.size.width/320)* 200 ; // 200 is your cell width which given in xib
        double bheight = (bWidth/320)* 250 // 250 is your cell height which given in xib;
        size = CGSizeMake(bWidth, bheight);

        return size;
    }
