title: UICollectionView and UIFocusGuide[s]
body: <p>I have a collection view with a varying number of cells. Under the collectionview is a button. When the focus in on a cell in line vertically with the button, I can move focus from the cell to the button. When the focus is on a cell that's not in a vertical line, I cannot give the button focus.</p>
  
  <p>Sounds like a job for UIFocusGuide! The Apple example shows two buttons and using the focus guide as the invisible "view" for focus. My actual question is: how do you do that with a collection view? Add focus guide[s] as cells? </p>
  
  <p>Has anyone used a Collectionview with focus guides and can offer advice?</p>
