Use NSLayoutConstraints in iOS6 to make a UITableView's footer, stick to the bottom of the last section and to the bottom of the UIScrollView?

Question

In Interface Builder, when working with a UITableViewController's table footer view, to which I added a blank view, it seems impossible to add constraints directly to it.

When I select the footer view of the table, and then select a constraint, all of the constraints are greyed out. Is this a bug or (more likely) am I wrongly assuming that you can't constrain a table footer view, to a UIScrollView

----- edit -----

Also, I have tried adding this in code...

[self.tableView.tableFooterView setTranslatesAutoresizingMaskIntoConstraints:NO];

//      Setup constraints
//
NSDictionary *viewsDictionary = @{@"superView" : self.view, @"tableView" : self.tableView,  @"tableFooterView" : self.tableView.tableFooterView};

//          Footer
//
[self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:[tableFooterView]|"
                                                                                       options:0
                                                                                       metrics:nil
                                                                                         views:viewsDictionary]];

But i just get this in the output:

I also got same error but in your case try to Temp Fix : Disabling the autoLayout in custom cell Xib, and then build
