Don’t perform data binding at this point, because there’s no cell on screen yet. For this you can use tableView:willDisplayCell:forRowAtIndexPath: method which can be implemented in the delegate of UITableView. The method called exactly before showing cell in UITableView’s bounds.

Apple doc: “A table view sends a tableView:willDisplayCell:forRowAtIndexPath: message to its delegate just before it draws a row. If the delegate chooses to implement this method, it can make last-minute changes to the cell object before it is displayed. With this method, the delegate should change only state-based properties that were set earlier by the table view, such as selection and background color, and not content.”
