I have a `UITableView`, I'm adding `tableFooterView` loaded from a xib.

```
var footer = NSBundle.mainBundle().loadNibNamed("AFooterView", owner: self, options: nil).first as! AFooterView
self.tableView.tableFooterView = footer

```

This works fine, but I need to be able to set the height for this footer. The xib only has a `UIImageView` centered vertically and horizontally so it will adapt whatever the height of the view is.

I have no clue how to do this with `AutoLayout`? What would be the right path to follow?
