Update tableView with AccessoryCheckmark when switching back to that TabView
<p>My app has 3 tabs, and the array that populates a tableView in third tab can be changed in the other two tabs. When I switch to the third tab, I need the tableView to be updated. I know how to do this, the only problem is that the table view is a check list.</p>

<p>When I tick some of the rows in the third tab, switch to another tab and update the 3rd tab's array, when I want to switch back to the third tab the table is updated with the new data but the checkmarks are removed from the table.</p>

<p>Is there a way to update the table without removing the checkmarks?</p>
