Well, it's a little complicated. There are 2 sections in the table view. The first section has 4 cells always, no more, no less. They like static but since the second section of the tableview is dynamic, I cannot make the tableview with static cells. So, when I get the information to display in those 4 cells, I thought to call the reloadRowsAtIndexPath:withRowAnimation:. Note that I'm not adding or removing cells. Its just that when the tableview appears, the data hasn't been received from the server. I just wanted to minimize the reload that the table view would have to do because the second section is dynamic and when I get the data for the first section, I query the server for the data of the second section, so when I have the data for the cells in section 1, I just want to reload that section.
Is there something wrong in my reasoning? Since the connection to the server is asynchronous, it is possible that I might be changing the number of rows in section 2, but I'm only trying here to reload section 1. Maybe my reasoning is wrong, that would explain why it fails. -Laurent. -- Laurent Daudelin AIM/iChat/Skype:LaurentDaudelin http://www.nemesys-soft.com/ Logiciels Nemesys Software laur...@nemesys-soft.com On Aug 22, 2012, at 00:02, Luke Hiesterman <luket...@apple.com> wrote: > You need to read the actual exception message.
