== Configuring Attachment Behavior ==

As the name suggests, the UIAttachmentBehavior class allows dynamic items to be configured such that they behave as if attached. These attachments can take the form of two items attached to each other or an item attached to an anchor point at specific coordinates within the reference view. The attachment can take the form of an imaginary piece of cord that does not stretch, or a spring attachment with configurable damping and frequency properties that control how “bouncy” the attached item is in response to motion.
