Call moveRowAt method in didSelectRowAt? - swift

Question

Is there a way that you can call
func tableView(_ tableView: UITableView, moveRowAt fromIndexPath: IndexPath, to toIndexPath: IndexPath) {
let affectedEvent = arrayMoved[fromIndexPath.row]
arrayMoved.remove(at: fromIndexPath.row)
arrayMoved.insert(affectedEvent, at: toIndexPath.row) }
in
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath){}

Answer 1

tableView(_:moveRowAt:to:) is a delegate method, meaning it is a method that you should implement and let the system call you, not the other way around — normally you should not call a delegate method yourself.
If you want to tell the system to move a row, simply call moveRow(at:to:) of the table view, e.g.
func tableView(_ tableView: UITableView, didSelectRowAt ip: IndexPath) {
tableView.moveRow(at: ip, to: IndexPath(row: 0, section: ip.section))
}
After communicating with OP, want OP actually wants to reorder the model to push the selected item to the end. The typical way to do this is something like:
func tableView(_ tableView: UITableView, didSelectRowAt ip: IndexPath) {
// update the model.
model[ip.row].value = maxOfValue + 1
sortModelAgain()
// reload the model (note: no animation if using this)
tableView.reloadData()
}
or, if you'd like to manually keep the view and model in sync:
func tableView(_ tableView: UITableView, didSelectRowAt ip: IndexPath) {
// update the model.
model[ip.row].value = maxOfValue + 1
sortModelAgain()
// change the view to keep in sync of data.
tableView.beginUpdates()
let endRow = tableView.numberOfRows(inSection: ip.section) - 1
tableView.moveRow(at: ip, to: IndexPath(row: endRow, section: ip.section))
tableView.endUpdates()
}
