Refresh certain row of UITableView based on Int in Swift

Question

I am a beginning developer in Swift, and I am creating a basic app that includes a UITableView. I want to refresh a certain row of the table using:

self.tabl         


        

Answer 1

How about:

self.tableView.reloadRowsAtIndexPaths([NSIndexPath(rowNumber)], withRowAnimation: UITableViewRowAnimation.Top)

Answer 2

You can create an NSIndexPath using the row and section number then reload it like so:

let indexPath = NSIndexPath(forRow: rowNumber, inSection: 0)
tableView.reloadRowsAtIndexPaths([indexPath], withRowAnimation: UITableViewRowAnimation.Top)

In this example, I've assumed that your table only has one section (i.e. 0) but you may change that value accordingly.

Update for Swift 3.0:

let indexPath = IndexPath(item: rowNumber, section: 0)
tableView.reloadRows(at: [indexPath], with: .top)

Answer 3

In Swift 3.0

let rowNumber: Int = 2
let sectionNumber: Int = 0

let indexPath = IndexPath(item: rowNumber, section: sectionNumber)

self.tableView.reloadRows(at: [indexPath], with: .automatic)

byDefault, if you have only one section in TableView, then you can put section value 0.

Answer 4

    extension UITableView {
        /// Reloads a table view without losing track of what was selected.
        func reloadDataSavingSelections() {
            let selectedRows = indexPathsForSelectedRows

            reloadData()

            if let selectedRow = selectedRows {
                for indexPath in selectedRow {
                    selectRow(at: indexPath, animated: false, scrollPosition: .none)
                }
            }
        }
    }

tableView.reloadDataSavingSelections()

Answer 5

let indexPathRow:Int = 0
let indexPosition = IndexPath(row: indexPathRow, section: 0)
tableView.reloadRows(at: [indexPosition], with: .none)
