title: How to make UICollection Scrolling Smoothy
body: <p>I created a collectionView. The cell is simple with only a UILabel on it. But the number of them is very much, for example, 33*50 +, in this case, view scrolls very laggy witch FPS 20 bellow.</p>
  
  <p>I tried</p>
  
  <ol>
  <li>change UILabel into CATextLayer</li>
  </ol>
  
  <p>2.use CoreGraphics . Use drawRect to draw NSString</p>
  
  <p>3.user YYText to draw async.</p>
