Change Vertical Spacing of CollectionView Cell

Am using UICollectionView and changing the size of the item in the delegate method of collection view like this

- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.

    lastIndex = 0;
    layoutDiff = 4;
}


- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath
{
    if(indexPath.row == (lastIndex + layoutDiff) - 1){
        layoutDiff = (layoutDiff == 4)?5:4;
        lastIndex = indexPath.row + 1;
        return CGSizeMake(213.2, 213.2);
    }

    return CGSizeMake(106.6, 106.6);
}

and here is my current screen.

enter image description here

and all the below cells to be follow this behaviour, means the pattern i want is like one collection view item to big depending on my logic where i want to make it big but i don't want this space. I think if the space will not b there then all things will be right. Can anyone help with this?

FlowLayout can't help with this.

You hava to implement your subclass of UICollectionLayout.

Here are some articles that take about custom Collection View Layout.
