i've been trying out zf2 couple of weeks , enjoy working it. have trouble though deciding specific tasks. function belong in model or in controller etc. @ moment understand view helper , controller plugin concepts. give few examples kind of functionality belongs in view helper? know same controller plugin, few examples make me understand why make plugin instead of programming functionality in controller? view helpers extend functionality on view layer , reusability throughout application. controller plugins extend functionality on controller layer. you use both keep controllers / views light , thin , reuse in application (keeping code dry).

here read in cells , table view performance guide : avoid relayout of content. when reusing cells custom subviews, refrain laying out subviews each time table view requests cell. lay out subviews once, when cell created. what mean ? am applying : override func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell { let cell = tableview.dequeuereusablecellwithidentifier("customcell", forindexpath: indexpath) as! customcell cell.customcelldescription.text = data[indexpath.row] return cell } what you're doing fine. putting data in label (or whatever is), not moving around. cellforrowatindexpath — apply cell data corresponds index path.
