copied!<p>This is pretty puzzling. Would you try removing the begin/endUpdates:</p> <pre><code>- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { [self.tableView reloadSections:[NSIndexSet indexSetWithIndex:indexPath.section] withRowAnimation:UITableViewRowAnimationTop]; } </code></pre> <p>I see that the crash is happening in <code>endUpdates</code>, so all the rest that has been executed up to that point has gone flawlessly.</p> <p>Another thing you might try is reloading the whole table by calling <code>reloadData</code> instead of only reloading the sections through <code>reloadSections</code>. This is not as optimized, but since you have few rows it should not matter actually (if it works better)...</p> <p>OLD ANSWER:</p> <p>It seems that one of the objects in your table view is being deallocated and then accessed again. This is a typical "zombie" issue.</p> <p>You can get some clues at what is happening by enabling zombie detection in Xcode.</p> <p><a href="https://stackoverflow.com/questions/5386160/how-to-enable-nszombie-in-xcode">Here you can find out how to enable zombies</a>.</p> <p>If you do, then the error message you get in the console log will offer more information as to which object was deallocated prematurely.</p> <p>I understand that you are attaching a crash log because the crash happens in the field. In this case, you have two options: either reproducing the issue at your side (and fix it with the help of zombies detection); or inspect carefully your memory management to find out any issue with objects displayed in the table view.</p>
