Can't scroll to bottom in UISearchResultsTableView

Question

I'm facing a really strange problem, where I can not scroll to the bottom in UISearchResultsTableViewaltough the frame of the tableView and the contentSize is correct.

It only happens if I click on "Cancel" and enter a new search string. If I clear this string and enter again, everything works fine. If I click "Cancel" again and enter a new string, I can't scroll to the bottom. It seems to me like the second search works, but I'm having a problem with the first search or after clicking the "Cancel" button in UISearchBar.

- (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString
{
    [self searchForText:searchString];
    return YES;
}

- (void)searchDisplayController:(UISearchDisplayController *)controller willShowSearchResultsTableView:(UITableView *)tableView
{
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide) name:UIKeyboardWillHideNotification object:nil];
}

- (void)searchDisplayController:(UISearchDisplayController *)controller didLoadSearchResultsTableView:(UITableView *)tableView
{
    tableView.rowHeight = 70;
}

- (void)searchDisplayController:(UISearchDisplayController *)controller didHideSearchResultsTableView:(UITableView *)tableView
{
    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillHideNotification object:nil];
}

- (void)keyboardWillHide
{

    UITableView *tableView = [[self searchDisplayController] searchResultsTableView];

    [tableView setContentInset:UIEdgeInsetsZero];

    [tableView setScrollIndicatorInsets:UIEdgeInsetsZero];
}

I've also subclassed my UISearchDisplayController

- (void)setActive:(BOOL)visible animated:(BOOL)animated
{
    if(self.active == visible) return;

    [self.searchContentsController.navigationController setNavigationBarHidden:YES animated:NO];
    [super setActive:visible animated:animated];
    [self.searchContentsController.navigationController setNavigationBarHidden:NO animated:NO];

    if (visible) {
       [self.searchBar becomeFirstResponder];
    } else {
       [self.searchBar resignFirstResponder];
    }
}

Additionally I'm also using a custom cell, which is registered like this

[self.searchDisplayController.searchResultsTableView
 registerNib:[UINib nibWithNibName:@"..." bundle:nil] forCellReuseIdentifier:@"..."];

I solve the problem, I think you need to check you tableview contentInset property in tableview "cellForRowAtIndexPath" method. It's not UIEdgeInsetsZero. I solved it by set tableview content Inset to UIEdgeInsetsZero in "cellForRowAtIndexPath" method. It's a little wired, but it works.
