    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)
