title: UICollectionView - distance between cells?
body: <p>I'm using a UICollectionView with the cell width of 67, right now I am using a flow layout.</p>
  
  <p>I have 3 cells in a row with 30px space between cells. How can make that distance less, so that I can fit four cells in a row? Does this method have something to do with it?</p>
  
  <pre><code> - (UIEdgeInsets)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout insetForSectionAtIndex:(NSInteger)section
   {
      return UIEdgeInsetsMake(10, 10, 10, 10);
   }
  </code></pre>
