reloading visible uicollectionviewcell when nested in uitableviewcell : <p>I have a UICollection that shows a padlock on cells that locked to users who aren't logged in. The user can view the collection and then login in a modal. When the modal dismisses, I am trying to reload the cells of the table and the nested collection to remove the padlocks from the cells.  </p>

<p>The visible cells are not refreshing to remove the padlock.  When the collection is scrolled, the cells offscreen are correct and show with padlock. I am calling reloaddata() on both the tableview and each nested collectionview.</p>

<p>The code I have is separated to:</p>

<h2>UIViewController</h2>

<pre><code>override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -&gt; UITableViewCell {

    let cell = tableView.dequeueReusableCellWithIdentifier("SectionWorkouts", forIndexPath: indexPath) as! SectionTableViewCell

        cell.delegate = self

        // Return the workouts count from the section
        let intIndex = indexPath.row

        let index = workoutSections.startIndex.advancedBy(intIndex)

        let currentWorkoutSectionKey = workoutSections.keys[index]

        if let currentWorkoutSection = workoutSections[currentWorkoutSectionKey] {

            cell.workoutsCollection.dataSource = sectionWorkoutsCell
            cell.workoutsCollection.delegate = sectionWorkoutsCell

            cell.updateCellWithWorkouts(currentWorkoutSectionKey, workouts: currentWorkoutSection)


        }

    }

    return cell
