Auto Resizing Tiles

[awaistariq]

Hello,
I have been playing with RFQuiltLayout.
Basically I need a layout like ZigZag tiles, something like this
|^|
|^|
|**^|

The first three rows gets drawn properly but later it auto resize the tiles and start messing with it.
Anyone can help?

Here is the code:
int counter = 4;

pragma mark – RFQuiltLayoutDelegate

- (CGSize) blockSizeForItemAtIndexPath:(NSIndexPath *)indexPath {

NSLog(@"%d and Row: %d",counter % 4, indexPath.row);

if(counter % 4 >= 2)
{
    counter++;

    if(indexPath.row >= self.numbers.count)
        NSLog(@"Asking for index paths of non-existant cells!! %d from %d cells", indexPath.row, self.numbers.count);

    if (indexPath.row % 2 == 0) {
        return CGSizeMake(2, 1);
    }else
    {
        return CGSizeMake(1, 1);
    }
}
else
{
    counter++;
    if(indexPath.row >= self.numbers.count)
        NSLog(@"Asking for index paths of non-existant cells!! %d from %d cells", indexPath.row, self.numbers.count);

    if (indexPath.row % 2 == 0) {
        return CGSizeMake(1, 1);
    }else
    {
        return CGSizeMake(2, 1);
    }
  }
