body: <p>I use feature of autosizing flow layout of collectionView</p>
  
  <pre><code>self.flow = [[UICollectionViewFlowLayout alloc] init];
  self.flow.scrollDirection = UICollectionViewScrollDirectionVertical;
  self.flow.sectionInset = UIEdgeInsetsZero;
  self.flow.estimatedItemSize = CGSizeMake(320, 48);
  </code></pre>
