iOS8 - constraints ambiguously suggest a height of zero

Question

Has anyone got any idea how to debug this?

Warning once only: Detected a case where constraints ambiguously suggest a height of zero for a tableview c

Answer 1

The constraints can be happy for the purpose of layout, but not happy for the purpose of automatic row height. A happy layout would mean the content can be laid out without ambiguity. That would satisfy the checks in Interface Builder.

A happy layout for automatic row height would mean that, in addition to the above, you're also including constraints to the bottom of the cell.
