UITableView Delete Row

Question

I am making a table view and I want to make a function where you can delete a row by swiping right and tapping the delete button. Me and my teacher have tried for about half an

Answer 1

This is because your numberOfRowsInSection data source implementation always returns 1 (fixed).

Typically, you store objects in an array, which defines the number of rows. And, commitEditingStyle should remove the object from the array and then delete the row.

– (void)tableView: (UITableView *)tableView commitEditingStyle: (UITableViewCellEditingStyle)editingStyle forRowAtIndexPath: (NSIndexPath *)indexPath {if (editingStyle == UITableViewCellEditingStyleDelete) {
       // Delete the row from the data source
       [maTheData removeObjectAtIndex:[indexPath row]];
       // Delete row using the cool literal version of [NSArray arrayWithObject:indexPath]

       [tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationFade];

    }
}

This swift function can delete a row by swiping right and tapping the delete button. Actually this function delete item from items array then delete row. In addition this row removed from tableView.

override func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
    if editingStyle == UITableViewCellEditingStyle.delete {
        // your items include cell variables
        items.remove(at: indexPath.row)
        tableView.deleteRows(at: [indexPath], with: UITableViewRowAnimation.automatic)
    }
}
