I put each section elements in separated arrays. Then put them into another array( arrayWithArray). My solution here for this problem:

[quarantineMessages removeObject : message];
[_tableView beginUpdates];
if([[arrayWithArray objectAtIndex: indPath.section] count]  > 1)
{
    [_tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indPath] withRowAnimation:UITableViewRowAnimationBottom];
}
else
{
    [_tableView deleteSections:[NSIndexSet indexSetWithIndex:indPath.section]
              withRowAnimation:UITableViewRowAnimationFade];
}
[_tableView endUpdates];

I had the same error.

I was using the following lines

UINib *myCustomCellNib = [UINib nibWithNibName:@"CustomNib" bundle:nil];
[tableView registerNib:myCustomCellNib forCellReuseIdentifier:@"CustomNib"];

to register the nib in the viewDidLoad method, since I had a different nib that was also associated with the same class. Hence, the line

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"GBFBLoadingCell"];

was returning nil unless I registered the nib in the viewDidLoad.

My problem was that I forgot to set the identifier in the attributes inspector for my file "CustomNib.xib" and "CustomNib~iphone.xib". (Or more precisely, that I forgot to press enter after typing the identifier in the attribute inspector in XCode, so that the new name failed to save.)

Hope this helps.
