Rows disappear while deleting if delete from down to up

I added possibility to remove rows from the list. After every removing the list is reloading. If remove rows from up to down everything is fine. But if remove rows from down to up all rows are disappear when all rows count is equal to visible rows count.

This is how my friend solved this problem:

edit PXListView.m

replace method:
-(void)enqueueCell:(PXListViewCell*)cell
{

[_reusableCells addObject:cell];
[_visibleCells removeObject:cell];
[cell setHidden:YES];
}

by this:
-(void)enqueueCell:(PXListViewCell*)cell
{
if (!cell)
return;

[_reusableCells addObject:cell];
[_visibleCells removeObject:cell];
[cell setHidden:YES];
}
