Instance Property


A Boolean value that determines whether the constraint should be archived by its owning view.


@property BOOL shouldBeArchived;


When a view is archived, it archives some but not all constraints in its constraints array. The value of shouldBeArchived informs the view if a particular constraint should be archived by the view.

If a constraint is created at runtime in response to the state of the object, it isn't appropriate to archive the constraint. Instead you archive the state that gives rise to the constraint. The default value for this property is NO.
