title: How to make a UICollectionViewCell's height to fill all the size of the frame?
body: <p>I'm trying to have a CollectionViewCell to fill all the frame of the CollectionView, however I've been unable to accomplished this, instead, it looks like this:
  <a href="http://i.stack.imgur.com/ef5pg.png" rel="nofollow">How it currently looks</a></p>
  
  <p>As you can see, there's a space at the top and the bottom of the uicollectionview frame, that should not appear.</p>
  
  <p>The configuration is the following:</p>
  
  <pre><code>//////////////////////////////
      //     Collection View      //
      //////////////////////////////
      self.collectionView.delegate = self
      self.collectionView.dataSource = self
  
      self.automaticallyAdjustsScrollViewInsets = false
  
      let screenWidth = UIScreen.mainScreen().bounds.width
      let viewHeight = viewContainer.frame.height
  
      let collectionViewFlowLayout = collectionView.collectionViewLayout as! UICollectionViewFlowLayout
      collectionViewFlowLayout.itemSize = CGSizeMake(screenWidth, viewHeight)
      collectionViewFlowLayout.minimumInteritemSpacing = 0.0
      collectionViewFlowLayout.minimumLineSpacing = 0.0
      collectionViewFlowLayout.sectionInset = UIEdgeInsetsMake(0.0, 0.0, 0.0, 0.0)
  </code></pre>
  
  <p>How can I delete this unwanted spaces?</p>
