The axis of the view that might be reduced.
The priority with which the view should resist being compressed from its intrinsic size on the specified axis.
The constraint-based layout system uses these priorities when determining the best layout for views that are encountering constraints that would require them to be smaller than their intrinsic size.
Subclasses should not override this method. Instead, custom views should set default values for their content on creation, typically to UILayoutPriorityDefaultLow or UILayoutPriorityDefaultHigh.
