title: 2 different cell sizes in UICollectionView Objective C
body: <p>I would like to use UICollectionView, it is possible to create the following layout:</p>
  
  <p><a href="https://i.stack.imgur.com/ZHPjY.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/ZHPjY.jpg" alt="something like that..."></a></p>
  
  <p>As you can see, there are two different sizes of the cell. One is 1/4 of the row, the other is 3/4. Is it possible to create this kind of layout with a UICollectionView?</p>
  
  <p>Would anyone can teach me how to do it??? Or is there any samples??? I have already study many tutorials and reference. But still dont know how to do it..</p>
  
  <p>Thanks!</p>
