Make sure your edits to the UITableView are inside begin/end updates. The changes don't appear until you call end. Make sure that by the time you call endUpdates that the new data is reflected in the table's data source. eg.

[tableView beginUpdates];
// ... inserts and deletes
[tableView endUpdates];
