Hi, i am trying to add a swipe to delete feature to the addmusic example project (downloaded free from apple) so that i am able able to delete a specific row.

Ive added the following code just so that i can enable to delete feature but i dont know how to remove the song from the list which i believe to be the mediaItemCollection and actually deleting it from the userMediaItemCollection which is used to queue the songs to the player.

- (void)tableView:(UITableView*)tableView willBeginEditingRowAtIndexPath:(NSIndexPath *)indexPath
{
}

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
    // If row is deleted, remove it from the list.
    if (editingStyle == UITableViewCellEditingStyleDelete)
    {
        // delete your data item here
        // Animate the deletion from the table.
[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath]withRowAnimation:UITableViewRowAnimationFade];
        }
    }

The swipe to delete feature works nicely, the delete button only appears when swiped, but when i click delete, a SIGBART error occurs, the whole application freezes, (although the musix does continue to play, lol). Can someone please tell me how i can delete the row at that index and how i can delete it from the mediaitemcollection please.

When taking that single line of code out:

[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath]withRowAnimation:UITableViewRowAnimationFade];

the swipe to delete works, except that it does not delete anything obviously since i havent added any actual delete functionality/coding that needs to be done.

All ideas appreciated.
