Populate ChatRoom Messages and Scroll To Bottom Without Animation Not Working

[benmarten]

How to populate existing chat messages already before the chat room view appears, without the scroll animation visible to the user?
I tried the below lines in my BORChatRoom subclass - it works, but the scroll animation animation is still visible to the user:

• (void)viewWillAppear:(BOOL)animated
  {
  [super viewWillAppear:animated];
  [self.chatCollectionViewController scrollToLastMessageAnimated:NO];
  }

Maybe you can lead me in the right direction, where to make modifications in your project?
