UITableViewCell checkmark change on select

Keep a property in your view controller called selectedRow, which represents the index of a row that represents the checked item in a table section.

In your view controller’s -tableView:cellForRowAtIndexPath: delegate method, set the accessoryType of the cell to UITableViewCellAccessoryCheckmark if the cell’s indexPath.row equals the selectedRow value. Otherwise, set it to UITableViewCellAccessoryNone.

In your view controller’s -tableView:didSelectRowAtIndexPath: delegate method, set the selectedRow value to the indexPath.row that is selected, e.g.: self.selectedRow = indexPath.row
