Some views also have what is known as an intrinsic content size. This is the preferred size that a view itself believes it needs to be to display its content to the user. A Button view, for example, will have an intrinsic content size in terms of height and width that is based primarily on the text or image it is required to display and internal rules on the margins that should be placed around that content. When a view has an intrinsic content size, Auto Layout will automatically assign two constraints for each dimension for which the view has indicated an intrinsic content size preference (i.e. height and/or width). One constraint is intended to prevent the size of the view becoming larger than the size of the content (otherwise known as the content hugging constraint). The other constraint is intended to prevent the view from being sized smaller than the content (referred to as the compression resistance constraint).
