The solution from romeo https://stackoverflow.com/a/2799675/661022 is cool, but I noticed that the code needs one more loop. I was working with tableViewController. I edited the script and then I checked. Everything worked perfect.

I recommed to try this:

- (void)findFirstResponder
{
    NSArray *subviews = [self.tableView subviews];
    for (id subv in subviews )
    {
        for (id cell in [subv subviews] ) {
            if ([cell isKindOfClass:[UITableViewCell class]])
            {
                UITableViewCell *aCell = cell;
                NSArray *cellContentViews = [[aCell contentView] subviews];
                for (id textField in cellContentViews)
                {
                    if ([textField isKindOfClass:[UITextField class]])
                    {
                        UITextField *theTextField = textField;
                        if ([theTextField isFirstResponder]) {
                            NSLog(@"current textField: %@", theTextField);
                            NSLog(@"current textFields's superview: %@", [theTextField superview]);
                        }
                    }
                }
            }
        }
    }
}
