Question

I use UIActionSheet to confirm for deleting row in TableView. I have 3 rows but when I swap to delete first row, the first row not delete but the third row is deleted. After I continue to delete first row again but second row is deleted. I don’t know why. Please help me to resolve this small problem.

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle
forRowAtIndexPath:(NSIndexPath *)indexPath
{

if (editingStyle == UITableViewCellEditingStyleDelete)
{

    UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:@"cancel" destructiveButtonTitle:@"Delete" otherButtonTitles: nil];

    [actionSheet showInView:self.view];

}

}





-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{


switch (buttonIndex) {
    case 0:

        [listOfName removeObjectAtIndex:self.selectedIndex];
         //selectedIndex = indexPath.row;
        [self viewWillAppear:YES];

}


}

Answer 1

Here is the problem

[listOfName removeObjectAtIndex:self.selectedIndex];

The value of selectedIndex of your UIActionSheet is always 0 since that is not set to the index of table row to be deleted.

Set it’s value to the indexPath.row before presenting the UIActionSheet.

self.selectedIndex = indexPath.row;
[actionSheet showInView:self.view];

Then in clickedButtonAtIndex: method within the case 0, make sure you reload the table view.

[tableView reloadData];
