title: collectionview in tableviewcell displays wrong data when reuse happens
body: <p>I am encountering a problem during the reuse of tableViewCells.</p>
  
  <p>I have a TableView. Each tableviewcell contains a UIView that holds a collection view. The datasource and delegate are set to that view. Each cell of that collection view displays one image.</p>
  
  <p>When I am scrolling now my tableview, the cells of the tableview are reused. In the cellForRowAtIndexPath I am setting the values of the cell (i.e. also for the delegate and datasource of the collection view).</p>
  
  <p>However, the reused cells do not update the images contained in the collectionviewcell. I already tried different positions for self.setNeedsDisplay() without success.</p>
  
  <p>Anybody has any suggestions where to trigger the correct reload?</p>
  
  <p>BR
