I have a view where I'd like to have a "header" type block (a bunch of labels inside a `UIView`) and then a table view below. The header is to be a fixed size and the table view should expand to the bottom of the view based on what device the application is being run on. 

The whole thing is inside a tab bar controller, and I have tried (I think) just about every possible constraint in Interface Builder to try to get the header to be fixed at the top, and the table view to fit the rest of the view, on either a 3.5" or 4" device. 

What is happening is that either the header fixes properly and the table view drops below the tab bar, or the header slides under the top nav bar, and the table drops below the tab bar, as well as getting a ton of constraint errors.
