title: SIGABRT with Editing Tables - IOS
body: <p>I have got the following code:</p>
  
  <pre><code> - (void)tableView:(UITableView *)tableView commitEditingStyle:   (UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
  
   if (editingStyle == UITableViewCellEditingStyleDelete) {
   [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationNone];
   [[delegate contentArray] removeObjectAtIndex:indexPath.row];
   [self.tableView reloadData];
  }
  if (editingStyle == UITableViewCellEditingStyleInsert) {
  }
  }
  </code></pre>
  
  <p>Now when I run it, the edit button works and the delete interface comes up, but I get a SIGABRT error when I press the delete button.</p>
  
  <p>I am not sure how to read the log files yet, but if you need them, tell me how to get them to you:-)</p>
  
  <p>EDIT:</p>
  
  <p>I have posted the console log here:</p>
