Answer 1

This is what I did to find what UITextField is the firstResponder when the user clicks Save/Cancel in a ModalViewController:

    NSArray *subviews = [self.tableView subviews];

for (id cell in 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]) {
                    [theTextField resignFirstResponder];
                }

            }
        }

    }

}
