• For programmatically created view default is true and for views from Interface Builder default is false

  If the property is (or set to) True, the system automatically creates a set of constraints based on the view’s frame and its autoresizing mask.

So When programmatically instantiating views, be sure to set their translatesAutoresizingMaskIntoConstraints property to NO.
