      Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints) </p>

      "&lt;NSLayoutConstraint:0x7c0ba210 H:[UIView:0x7c0bb900]-(8)-|   (Names: '|':UIView:0x7c0b6c20 )&gt;",

      "&lt;NSLayoutConstraint:0x7c635250 'UIView-Encapsulated-Layout-Width' H:[UIView:0x7c0bbfa0(2)]&gt;"
  )
  
  Will attempt to recover by breaking constraint
