在搜索模式下从UITableView中删除标题标题

Question

Just noticed some undesired behavior in my UITableView, when it's in search mode. Here is a visual description of the issue, with my suspected method implementation at the bottom.

(Step 1) The Complete List - OK!

---

(Step 2) Search Results - OK!

---

(Step 3) Drill Into a Search Result - OK!

---

(Step 4) Navigate Back to Search Results - Not OK! All Header indexes are being returned...

---

Here is my method implementation that is returning all of the indices:

-(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
    NSArray *sKeysArray = [[listContent allKeys] sortedArrayUsingSelector:@selector(caseInsensitiveCompare:)];

    sorted = [sKeysArray sortedArrayUsingComparator:self.mySortBlock];

    if (tableView == self.searchDisplayController.searchResultsTableView){

        return @"";

   } else {

    return [sorted objectAtIndex:section];
  }

}

What are best practices to solve this issue?

Thanks

I observed this behavior if [self.tableView reloadData] is called within viewWillAppear: or viewDidAppear: .

It seems that reloadData causes all section headers of the underlying table view to appear even if a search is active and only the searchResultsTableView should be visible.

A solution could be to call reloadData only if [self.searchDisplayController isActive] == NO .
