ASControlNode is the ASDK equivalent to UIControl. You don't create instantce of ASControlNode directly. Instead, you can use it as a subclassing point when creating controls of your own. In fact, <a href = "#">ASTextNode</a> and <a href = "#">ASImageNode</a> are subclasses of ASControlNode which means they can easily be used in the same way you would normally use a UIButton.

In fact, <a href = "/docs/text-node.html">ASTextNode</a>, <a href = "/docs/image-node.html">ASImageNode</a>, <href = "#">ASVideoNode</a> and <a href = "/docs/video-node.html">ASMapNode</a> are all subclasses of ASControlNode.
This fact is especially useful when it comes to image and text nodes. Having the ability to add target-action pairs means that you can use any text or image node as a button without having to rely on creating gesture recognizers, as you would with text in UIKit, or creating extraneous views as you might when using UIButton.
### Control State
Like UIControl, ASControlNode has a state which defines its appearance and ability to support user interactions. Its state can be one of any state defined by `ASControlState`.

Assigning a target and action for these events is done with the same methods as a UIControl, namely using `–addTarget:action:forControlEvents:` or `–actionsForTarget:forControlEvent:`.
