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

I was using a mapView inside uitableviewcell. I changed the height of map view to 1/3th of the device screen size. I got the same error. I fixed the error by adding missing constraints to the content view of the uitableviewcell.

1) Clear the contentView constraints.

2) Set Reset to Suggested constants to contentView.

3) Add missing constraints - if any

4) We make sure the content view has all the required constraints.
